P116 Internally Mounted Cylinder Sensor

Position feedback for industrial and scientific applications


This sensor at a glance

Maximum measurement 600mm

Longer operating life than a potentiometer

Fast delivery options available

Body Diameter: 27mm

Sealed to IP67

Independent Linearity:
< ±0.25%

Resolution: Infinite

Temperature range: -40° to +125°C (depending on electronics version)

The P116 linear sensor is designed to be fitted inside hydraulic or pneumatic cyliners allowing the external cylinder design to be unaffected. it is an extremely durable, high accuracy device providing position feedback for applications where service life, environmental resistance and cost are important. 

The P116 is particularly suitable for OEMs where very competitive volume pricing and unmatched overall performance make it a very attractive option. The sensor has fully integrated electronics with a variety of voltage and current outputs so no need for any external signal conditioning.

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 0-5mm to 0-600mm in increments of 1mm. For example, if your application requires 10" (254 mm) measurement, then Positek will manufacture the sensor specifically for this length. The mechanical length and calibration will be set up for 254 mm.
