P118 Linear Position Sensor

The P118 with its compact 19 mm diameter stainless steel body is an affordable, durable, accurate position sensor designed for a wide range of industrial applications. It is particularly suitable for OEMs seeking good sensor performance in situations where a small diameter, short-bodied sensor is needed and cost is important. The unit is compact and space-efficient, being responsive along almost its entire length, and like all Positek® sensors provides a linear output proportional to displacement.

Each unit is supplied with the output calibrated to the travel required by the customer, from 0-2mm to 0-50mm and with full EMC protection built in.

Overall performance, repeatability and stability are outstanding over a wide temperature range. The sensor is easy to install and set up. Mounting options include body clamps or a stainless steel mounting flange with two 3.2 mm by 30 degree wide slots on a 25 mm pitch. The stainless steel plunger can be supplied free or captive, with female M4 thread, or spring-loaded with a ball end. The P118 also offers a range of mechanical options, environmental sealing is to IP67.

All of Positek’s position sensors are manufactured to the highest quality and use our very own patented non-contact technology. This helps to ensure the highest levels of accuracy and reliability, even in the harshest of environments. Every position sensor that Positek manufactures uses their inductive sensor technology to ensure high-precision results, and is fully customisable to meet the unique requirements of your business.

With over 25 years’ experience as a sensor manufacturer and using our onsite production facility, Positek has the flexibility to manufacture and customise any industrial position sensor, including tilt sensors and inclinometers, to any size or specification.

Positek offers a range of options for its standard sensors. Each sensor is manufactured to suit each customer's preferences. If your requirement is outside the options given below, Positek can modify/ redesign a sensor to suit your specific requirement. Standard options are available as below:

 

Measurement Range

Factory set to any length from 0-2mm to 0-50mm in increments of 1mm. For example, if your application requires 1" (25 mm) measurement, then Positek will manufacture the sensor specifically for this length. The mechanical length and calibration will be set up for 25 mm.
