Heavy-Duty Electronic Accelerator Pedal Design
The accelerator pedal is one of the primary interfaces between an operator and a vehicle’s propulsion system. In modern electronically controlled vehicles, the accelerator pedal must perform considerably more than simply provide mechanical movement. It must accurately translate the operator’s pedal position into an electrical signal that can be interpreted by an electronic control unit or engine management system.
The Williams Controls WM-526 has been designed specifically to perform this function in demanding heavy-duty applications. As the operator moves the treadle through its available travel, the pedal’s sensing system detects the position and produces a corresponding electrical output. The receiving vehicle controller can then use this information to determine the requested engine speed, torque or other propulsion command according to the vehicle’s control strategy.
This electronic approach eliminates the requirement for a conventional mechanical accelerator linkage between the pedal and engine in suitable electronically controlled applications. Electronic throttle control can provide vehicle manufacturers with greater flexibility in component placement, system integration and control strategy while reducing the number of mechanical linkage components required throughout the vehicle.
The WM-526 combines this electronic functionality with the rugged construction required for commercial vehicle environments. Rather than being intended for light-duty or low-cycle applications, the pedal has been developed to withstand the repetitive operation and environmental exposure associated with professional vehicle and mobile equipment use.
Rugged Cast Aluminium Treadle Construction
Mechanical durability is a critical consideration when selecting a floor-mounted accelerator pedal for a commercial or industrial vehicle. The treadle may be operated thousands of times during a working shift and can be exposed to substantial forces throughout the vehicle’s service life.
The WM-526 incorporates a corrosion-resistant cast aluminium treadle designed to provide an effective combination of strength, durability and resistance to demanding operating environments. Aluminium construction provides a robust pedal structure while helping manage overall component weight and corrosion resistance.
The treadle is supported by a coated steel mounting base, providing a strong foundation for installation into the vehicle floor or appropriate mounting structure. This combination of materials helps provide the mechanical integrity required for heavy-duty operation while protecting the assembly against environmental exposure.
A durable NBR rubber cover is incorporated onto the treadle surface. The rubber covering helps provide traction between the operator’s footwear and the pedal, contributing to controlled pedal movement during normal vehicle operation.
This can be particularly important in working vehicles where operators may enter the cab wearing footwear exposed to rain, mud, dust or other contaminants. A defined treadle surface assists the operator in maintaining consistent foot contact with the accelerator during operation.
Designed for High-Cycle Commercial Vehicle Operation
One of the defining requirements of a heavy-duty accelerator pedal is its ability to withstand repeated operation over an extended service period. Vehicles used in transport, material handling, municipal services and other professional applications can accumulate extremely high numbers of accelerator pedal movements.
The Williams Controls WM-526 has been designed for a product life of up to 10 million full-travel cycles. This high-cycle capability demonstrates the emphasis placed on durability and makes the pedal suitable for applications where long operating life is an important component selection criterion.
A full-travel cycle represents movement of the pedal through its operating range and back again. Over the lifetime of a commercial vehicle, these cycles can accumulate rapidly, particularly in applications involving frequent acceleration and deceleration.
The pedal is also specified to withstand a static load of 1500 N. This mechanical load capability further demonstrates the robust construction of the WM-526 and its suitability for demanding commercial vehicle environments.
Combining high-cycle durability with substantial mechanical load capability provides OEM designers and equipment manufacturers with an accelerator pedal platform developed around the requirements of heavy-duty service rather than general-purpose operator control.
Advanced Non-Contact Hall-Effect Technology
The WM-526 can incorporate non-contact Hall-effect sensing technology to accurately detect pedal position. Hall-effect sensing is particularly valuable in demanding electronic throttle applications because pedal movement can be measured without relying on conventional contacting position-sensing elements for every operating cycle.
As the treadle moves, the Hall-effect sensor detects the changing position and produces an electrical signal corresponding to accelerator demand. This information can then be transmitted to the vehicle’s electronic control system.
The non-contact nature of Hall-effect technology contributes to long-term durability because it reduces dependence on mechanically contacting sensing surfaces that may otherwise experience wear through repeated movement.
This technology complements the WM-526’s high-cycle mechanical design and provides an electronic sensing solution suitable for applications requiring accurate, repeatable and dependable pedal position information.
The sensing system can be configured to suit different electronic control architectures, making the WM-526 a flexible solution for vehicle manufacturers and equipment designers working with a variety of engines, controllers and electronic systems.
Multiple Electronic Output Configurations
Heavy-duty vehicles and mobile machines utilise many different engine management and vehicle control architectures. As a result, accelerator pedal output requirements can vary substantially between applications.
The Williams Controls WM-526 platform addresses this requirement through a range of available electronic output configurations. Depending on the selected model and application requirements, configurations can include APS, Dual APS, PWM, Dual PWM and combined APS/IVS arrangements.
APS, or Accelerator Position Sensor, configurations provide electronic pedal position information to the receiving controller. Dual APS configurations provide multiple position signals that can be used within electronic control architectures requiring redundant or comparative signal channels.
PWM, or Pulse Width Modulation, configurations provide another method of transmitting accelerator position information to compatible electronic controllers. Dual PWM arrangements can also be specified where the system architecture requires multiple PWM outputs.
Combined APS and IVS arrangements can provide accelerator position information together with an Idle Validation Switch function. The appropriate configuration depends upon the engine controller, vehicle electronics and overall control strategy of the application.
Because different WM-526 configurations may have different electrical characteristics, customers should confirm the required sensor output, supply voltage, connector and signal characteristics before specifying a pedal. Control Devices can assist with identifying an appropriate Williams Controls WM-526 configuration for the intended system.
Flexible Voltage and Sensor Options
Electrical compatibility is an essential consideration when integrating an electronic accelerator pedal into a new or existing vehicle platform. Depending on the selected configuration, the WM-526 can accommodate different operating voltage and sensing requirements.
Available configurations include 5 V operation as well as arrangements suitable for 12 V and 24 V systems. This flexibility enables the WM-526 family to support a broad range of commercial vehicle and mobile equipment electrical architectures.
The Hall-effect sensor can be programmed for analogue output and integrated switching functions according to application requirements. Contact and PWM sensor options may also be available for configurations requiring alternative electrical interfaces.
This ability to configure the pedal around the receiving electronic system provides OEMs and system integrators with considerable design flexibility. Rather than adapting the entire vehicle control architecture around a fixed accelerator output, an appropriate WM-526 configuration can be selected to complement the intended electronic system.
Electronic Throttle Control for Modern Heavy-Duty Vehicles
The transition from traditional mechanical throttle systems to electronic throttle control has enabled vehicle manufacturers to integrate accelerator demand more closely with engine management and other vehicle functions.
In an electronic throttle control system, the accelerator pedal provides an electrical representation of the operator’s requested input. The electronic control unit then interprets this signal according to the programmed control strategy before commanding the appropriate engine or propulsion response.
This architecture can provide greater flexibility than a direct mechanical connection because accelerator demand can be incorporated into a broader electronic control strategy. Depending on the vehicle design, the accelerator signal may interact with engine management, transmission control, speed management and other vehicle functions.
The WM-526 provides the operator interface required for these systems while retaining the physical characteristics expected from a conventional floor-mounted heavy-duty accelerator pedal.
This combination of familiar operator control, rugged mechanical construction and configurable electronic sensing makes the Williams Controls WM-526 a practical solution for manufacturers transitioning between mechanical and electronically controlled vehicle platforms as well as for established electronic throttle applications.
Engineered for Harsh Environmental Conditions
Commercial vehicle components must continue operating reliably despite exposure to environmental conditions that can vary dramatically throughout the working life of the equipment. Temperature extremes, humidity, dust, vibration and moisture can all affect electronic and mechanical components if they are not designed appropriately.
The Williams Controls WM-526 has been engineered with these operating environments in mind. Its electronic components are sealed to IP67 in accordance with IEC 60529, providing a high level of protection against dust ingress and water exposure under the conditions defined by the rating.
The pedal is specified for operation across a broad temperature range from -40°C to +85°C. This wide operating range makes the WM-526 suitable for equipment expected to work across diverse climates and environmental conditions.
Resistance to environmental exposure is particularly valuable in vehicles that operate outdoors, travel between different climatic regions or work in industries where dirt, moisture and contamination are routinely present.
Combined with its rugged mechanical construction, environmental sealing helps make the WM-526 a dependable accelerator control solution for demanding professional vehicle applications.
Heavy-Duty Construction for Demanding Vehicle Environments
The Williams Controls WM-526 Electronic Floor Pedal has been engineered specifically for demanding commercial vehicle and heavy-duty equipment applications where mechanical strength, environmental resistance and dependable throttle control are essential. Its robust construction makes the pedal particularly well suited to vehicles and machinery that operate for extended periods under challenging conditions, including vibration, temperature extremes, dust, moisture and repeated operator use.
At the centre of the WM-526 design is a corrosion-resistant cast aluminium treadle combined with a coated steel mounting base. This construction provides the mechanical strength required for demanding accelerator and electronic throttle control applications while helping the assembly withstand the environmental exposure commonly encountered inside commercial vehicle cabs and operator compartments.
The treadle incorporates a durable NBR rubber cover designed to provide improved foot traction. This is particularly valuable in industrial and commercial vehicle environments where an operator’s footwear may be exposed to moisture, dirt or other contaminants. By providing a defined and secure contact surface, the treadle design contributes to predictable pedal operation throughout the working day.
Mechanical durability is another important characteristic of the WM-526. The pedal is specified to withstand a static load of 1500 N, demonstrating the strength of the assembly for demanding operator-controlled applications. It has also been designed and tested for a product life of up to 10,000,000 full-travel cycles, supporting applications where accelerator operation occurs continuously throughout the service life of a vehicle or machine.
Non-Contact Hall-Effect Sensing Technology
A major advantage of the WM-526 Electronic Floor Pedal is its use of Hall-effect non-contact sensing technology. Rather than relying solely on mechanically contacting elements to determine pedal position, the non-contact sensor can detect treadle movement electronically and provide the corresponding position signal to the vehicle’s electronic control system.
Non-contact sensing is particularly advantageous in heavy-duty throttle applications because it reduces reliance on components that physically contact one another during every operating cycle. This technology supports excellent durability and consistent signal performance across the long operational life expected from commercial vehicle control equipment.
As the operator depresses or releases the treadle, the sensor detects the corresponding angular position and generates the required electrical output. This signal can then be interpreted by the vehicle or machine’s electronic control system to determine the requested throttle or engine power command.
The WM-526 can be configured with a variety of electrical output arrangements, allowing the pedal to be adapted to different electronic control architectures. Available output configurations include APS, Dual APS, PWM, Dual PWM and combined APS/IVS arrangements. This flexibility makes the WM-526 suitable for integration into a broad range of electronic throttle control systems.
The Hall-effect sensor can also be programmed for analogue output and/or integrated switching functions. Where required by the application, the pedal may additionally be customised with contact or PWM output sensors. This configurable approach enables vehicle manufacturers, system integrators and equipment designers to select a sensing arrangement appropriate for the electrical interface and control strategy of the intended application.
Flexible Electrical Integration
Commercial vehicles and mobile equipment can utilise substantially different electrical and electronic architectures depending on the engine, controller, vehicle platform and intended application. For this reason, flexibility at the electrical interface is an important consideration when selecting an electronic accelerator pedal.
The WM-526 supports operating voltage configurations including 5 V as well as 12 V to 24 V arrangements, depending on the selected pedal configuration. Combined with the available sensor and output options, this allows the WM-526 platform to accommodate a wide variety of vehicle control requirements.
Dual-channel configurations can also support applications where independent position signals are required by the electronic control architecture. In these systems, multiple accelerator position signals can allow the receiving controller to compare channels as part of the overall system monitoring strategy.
Because the WM-526 is highly configurable, the exact electrical specification, connector arrangement and output characteristics should always be selected according to the requirements of the vehicle, engine management system or electronic controller. Control Devices can assist customers in identifying an appropriate WM-526 configuration for new installations, replacement requirements and OEM applications.
IP67-Sealed Electronics
Electronic controls installed in commercial vehicles must be capable of operating reliably in environments that can be considerably more demanding than conventional indoor electronic applications. Moisture, dust, contamination and cleaning processes can all present challenges to electronic components installed in vehicle operator areas.
The WM-526 addresses these conditions through electronics sealed to IP67 in accordance with IEC 60529. The IP67 sealing specification provides a high level of protection against dust ingress and temporary water immersion under the conditions defined by the standard.
This environmental sealing contributes to the WM-526’s suitability for commercial vehicles and mobile machinery operating in industries where equipment may regularly encounter dust, dirt and moisture. It also provides additional protection for the internal electronic sensing system, helping maintain reliable accelerator position measurement throughout demanding operating conditions.
For fleet operators and equipment manufacturers, environmental sealing can contribute to improved long-term reliability by helping protect critical electronic components from external contaminants. This is particularly important for an accelerator pedal, which performs a fundamental operator input function and can experience extensive use throughout the service life of the equipment.
High Resistance to Electromagnetic Interference
Modern commercial vehicles contain an increasing number of electronic systems, including engine management controllers, communication networks, displays, telematics, power electronics and auxiliary control equipment. These systems can generate electromagnetic activity that must be considered when integrating electronic sensors and operator controls.
The WM-526 electronics are designed for high electromagnetic interference resistance and are compliant with SAE J1113 requirements. This characteristic helps support dependable sensor operation in electrically demanding vehicle environments.
Electromagnetic compatibility is particularly important for an electronic accelerator pedal because the output signal is used by the receiving electronic control system to determine operator demand. A pedal designed for the heavy-duty vehicle environment therefore requires both mechanical durability and appropriately engineered electronic performance.
By combining non-contact Hall-effect sensing with environmental sealing and EMI-resistant electronics, the WM-526 provides a robust electronic throttle control interface suitable for integration into modern commercial vehicle systems.
Designed for Extreme Operating Temperatures
Commercial and off-highway vehicles may be required to operate across dramatically different climatic conditions. Equipment may experience sub-zero temperatures during winter operation and elevated temperatures when working in hot environments or enclosed operator compartments.
The WM-526 has a specified operating temperature range from -40°C to +85°C, with the same -40°C to +85°C range specified for storage. This broad temperature capability supports applications across a wide variety of climates and operating environments.
Such temperature resistance is particularly valuable for vehicles and machines expected to remain outdoors for extended periods or operate in remote locations where environmental conditions cannot be tightly controlled. Whether used in transport, construction, material handling or other commercial vehicle applications, the pedal is designed to provide dependable operation throughout a broad environmental range.
Resistance to Vibration, Humidity, Sand and Dust
Vibration is an unavoidable characteristic of many heavy-duty vehicles and mobile machines. Engine operation, road conditions, drivetrain movement and machine activity can continuously transmit vibration through the vehicle structure and into mounted components.
The WM-526 is specified for three-hour, three-axis random broadband vibration testing at levels up to 4 g. This provides an indication of the pedal’s suitability for applications where vibration resistance is an important part of component selection.
Environmental testing also includes resistance to high humidity, with the WM-526 specified for exposure to 95% relative humidity for 120 hours. Sand and dust resistance has additionally been tested to SAE J1455 requirements, further supporting its suitability for demanding commercial vehicle environments.
These characteristics make the WM-526 particularly relevant to applications where an accelerator pedal must provide dependable performance despite continuous environmental exposure. Rather than being designed solely around normal passenger vehicle conditions, the WM-526 is engineered as a heavy-duty electronic control intended for professional commercial vehicle applications.
Multiple Pedal Angles for Installation Flexibility
Vehicle cab geometry and operator positioning can vary considerably between different commercial vehicle platforms. Floor height, seat position, available mounting space and desired operator ergonomics can all influence the most appropriate accelerator pedal configuration.
To accommodate different installation requirements, the WM-526 is available with three treadle angle options: 28.5°, 35° and 45°. These alternatives provide designers and vehicle manufacturers with greater flexibility when integrating the pedal into different operator compartments and floor layouts.
Selecting the appropriate treadle angle can assist with achieving a comfortable and practical relationship between the driver’s seating position, foot position and accelerator pedal. This can be particularly important in vehicles operated for long working shifts, where operator comfort and predictable control positioning contribute to the overall usability of the machine.
The different pedal angles also make the WM-526 platform adaptable across multiple vehicle types without requiring an entirely different electronic accelerator concept for each installation. Combined with its configurable sensing and output arrangements, this mechanical flexibility makes the WM-526 a versatile solution for both OEM and specialised vehicle applications.
Kickdown and Non-Kickdown Configurations
The WM-526 is available in both kickdown and non-kickdown versions, providing additional flexibility for different vehicle control strategies. A kickdown function can provide a defined change in pedal feel or additional pedal action near the end of travel, depending on the selected application and configuration.
For applications where this functionality is unnecessary, a non-kickdown version provides a conventional pedal response throughout its operating range. The availability of both arrangements enables the pedal to be tailored more closely to the requirements of the vehicle manufacturer and the intended operating characteristics of the equipment.
This configurability is an important feature of the WM-526 family. Rather than offering a single fixed accelerator pedal specification, the platform can be adapted through combinations of pedal angle, sensing technology, output signal and kickdown functionality.
Suitable for Commercial and Heavy-Duty Vehicle Applications
The Williams Controls WM-526 has been developed around the requirements of commercial vehicle applications and can be considered for a broad range of heavy-duty vehicle and mobile equipment platforms. Typical applications may include trucks, buses, coaches, specialised commercial vehicles and other equipment requiring a rugged floor-mounted electronic accelerator control.
Its combination of a strong cast aluminium treadle, coated steel mounting plate, NBR rubber treadle cover, non-contact sensing technology and sealed electronics makes the WM-526 particularly well suited to installations where conventional light-duty accelerator components may not provide the required level of environmental or mechanical durability.
The ability to select different electronic outputs also provides engineers with flexibility when integrating the pedal with various engine management systems and electronic controllers. This makes the WM-526 suitable for both established commercial vehicle platforms and specialised OEM equipment where application-specific electronic interfaces may be required.
For Australian equipment manufacturers, vehicle builders, fleet operators and system integrators, Control Devices can assist with selecting a Williams Controls WM-526 configuration suited to the application’s mechanical, environmental and electrical requirements.
Engineered for Commercial Vehicle Applications
The Williams Controls WM-526 Electronic Floor Pedal is designed for demanding commercial vehicle applications where dependable accelerator control, mechanical durability and environmental resistance are essential. Its combination of heavy-duty construction and configurable electronic sensing makes the pedal suitable for integration into a wide variety of electronically controlled vehicle platforms.
Potential applications include commercial trucks, buses, coaches, specialised transport vehicles, vocational vehicles and other mobile equipment requiring a robust floor-mounted electronic accelerator pedal. The WM-526 can also provide a practical solution for specialist OEM equipment where conventional automotive accelerator pedals may not offer the durability or configuration flexibility required.
For vehicle manufacturers and system integrators, the ability to select from different sensing technologies, electrical outputs and mechanical configurations can simplify the process of matching the accelerator pedal to the intended control system.
The WM-526 should always be selected according to the requirements of the specific vehicle, electronic control unit and operating environment. Electrical compatibility, pedal geometry, mounting arrangements and required output characteristics should therefore be considered during the specification process.
Ideal for Trucks and Heavy Transport Vehicles
Heavy transport vehicles can place significant demands on accelerator pedal assemblies. Long operating hours, repeated acceleration cycles, vibration and changing environmental conditions mean that the pedal must provide consistent operation throughout an extended service life.
The WM-526 is particularly well suited to these demanding operating conditions. Its cast aluminium treadle and coated steel mounting base provide a robust mechanical platform, while the available non-contact Hall-effect sensing technology supports accurate electronic accelerator position measurement.
For truck manufacturers and specialised vehicle builders, the floor-mounted design provides a conventional accelerator interface while allowing the pedal to communicate electronically with compatible engine management and vehicle control systems.
The availability of multiple treadle angles also provides additional flexibility when designing the driver’s footwell and seating position. With 28.5°, 35° and 45° treadle angle options available, an appropriate configuration can be selected to suit different cab layouts and operator arrangements.
Electronic Accelerator Control for Buses and Coaches
Buses and coaches represent another application where accelerator pedal reliability can be particularly important. These vehicles may operate for extended periods each day and can accumulate substantial numbers of accelerator cycles through urban, regional and long-distance operation.
The WM-526’s design life of up to 10 million full-travel cycles makes it a strong candidate for high-utilisation vehicle platforms where long-term pedal durability is required.
Electronic accelerator control can also simplify integration between the driver’s accelerator input and modern electronically controlled powertrains. The WM-526 can provide the required pedal position signal while offering several output configurations to accommodate different vehicle electronic architectures.
Depending on the selected configuration, options including APS, Dual APS, PWM, Dual PWM and APS/IVS arrangements enable the pedal platform to be matched to the requirements of compatible engine or vehicle controllers.
Suitable for Special-Purpose and Vocational Vehicles
Special-purpose vehicles frequently require components capable of operating in conditions beyond those encountered in conventional passenger vehicles. Applications can include emergency support vehicles, municipal equipment, refuse vehicles, service vehicles, specialised transport platforms and other purpose-built commercial equipment.
These applications can expose accelerator pedals to repeated use, vibration, dirt, moisture and significant temperature changes. The WM-526 addresses these requirements through a combination of rugged construction, sealed electronics and environmental resistance.
The pedal’s IP67-rated electronics provide protection against dust and water ingress in accordance with the applicable rating conditions, while the broad -40°C to +85°C operating temperature range supports use across demanding climatic environments.
For specialist vehicle manufacturers, the configurable nature of the WM-526 can also be beneficial where a standard production accelerator pedal does not provide the required electrical interface or mechanical arrangement.
Designed with Operator Control in Mind
While durability and electronic performance are essential, an accelerator pedal must also provide a practical interface for the vehicle operator. The WM-526 maintains the familiar floor-mounted treadle arrangement widely used in heavy commercial vehicle applications.
The NBR rubber treadle cover provides a defined contact surface for the operator’s footwear and assists with maintaining consistent foot contact during normal pedal operation. This is particularly relevant in working environments where footwear may be exposed to dust, moisture or other contaminants.
The availability of different treadle angles provides vehicle designers with additional flexibility when considering the relationship between the seat, cab floor and accelerator pedal. Appropriate pedal positioning can contribute to a practical operator environment, particularly in vehicles used for extended working shifts.
Kickdown and non-kickdown configurations further expand the available options, enabling the pedal characteristics to be selected according to the intended vehicle control strategy.
Long Service Life and Reduced Mechanical Wear
Component service life is an important consideration for commercial vehicle manufacturers and fleet operators. Accelerator pedals can experience exceptionally high numbers of operating cycles, making durability a critical factor when selecting a suitable electronic throttle control.
The WM-526 has been designed for up to 10 million full-travel cycles. This high-cycle design capability is complemented by the availability of non-contact Hall-effect sensing technology.
Because Hall-effect sensing can determine pedal position without relying on conventional contacting sensing surfaces, mechanical wear within the position sensing system can be reduced. This characteristic makes non-contact technology particularly attractive for high-cycle accelerator applications.
The rugged mechanical construction of the pedal further supports its suitability for long-term commercial use. A corrosion-resistant cast aluminium treadle and coated steel mounting base provide a strong structural foundation, while the pedal is specified to withstand a static load of 1500 N.
Together, these characteristics provide a pedal platform designed around the durability expectations of professional vehicle and equipment applications.
Reliable Performance in Harsh Environments
Heavy-duty vehicles may encounter substantially different operating conditions throughout their working lives. A truck may travel through hot, dusty environments before encountering heavy rain, cold temperatures or high humidity. Mobile equipment may similarly be exposed to vibration, contamination and repeated environmental changes.
The WM-526 has been developed to provide dependable operation across these challenging conditions. The electronics are sealed to IP67 in accordance with IEC 60529, helping protect the internal sensing system against dust and water exposure.
The specified operating and storage temperature range of -40°C to +85°C further demonstrates the pedal’s suitability for demanding vehicle environments.
The WM-526 is also designed to withstand demanding vibration conditions and environmental exposure, including high humidity and sand and dust testing. These characteristics are particularly important for components installed in vehicles expected to remain operational in challenging industrial and commercial environments.
Electronic Compatibility and System Integration
Correct integration of an electronic accelerator pedal requires consideration of more than its physical mounting dimensions. The electrical characteristics of the pedal must be compatible with the electronic controller receiving the accelerator position signal.
Depending on configuration, the WM-526 can provide several different output arrangements. These include accelerator position sensor outputs, dual accelerator position signals, pulse width modulation outputs and combinations incorporating idle validation functionality.
Before selecting a WM-526, designers should identify the required supply voltage, output signal type, signal range, connector configuration and any redundancy or validation requirements specified by the receiving control system.
Mechanical considerations should also include the available mounting space, treadle angle, pedal travel and relationship between the accelerator pedal and operator seating position.
Correctly matching these characteristics is important when integrating the WM-526 into either a new OEM vehicle platform or an existing electronic throttle control system.
Replacement and Retrofit Considerations
When considering the WM-526 as a replacement electronic accelerator pedal, the complete specification of the existing pedal should be confirmed rather than selecting a replacement based solely on physical appearance.
Electronic accelerator pedals that appear mechanically similar may utilise different supply voltages, output curves, sensor configurations, connectors or signal strategies. Installing an electrically incompatible pedal can prevent correct operation of the vehicle control system.
Where an existing WM-526 part number is available, this information can assist with identifying the appropriate replacement configuration. For older equipment or applications where the original pedal specification is unclear, additional vehicle and controller information may be required.
Control Devices can assist customers with identifying suitable Williams Controls electronic pedal configurations based on available part numbers, application information and system requirements.
