LPPS-SL series Spring Loaded Linear Potentiometer Travel Sensors are used to monitor and track the linear motion or position of a target.. These compact sensors are ideal for use in gauging applications including laboratory, automotive, industrial, motion control, medical, and aerospace.

Resistive potentiometric element is made from conductive plastic. Output is ratiometric; from 0% to 100% of excitation voltage.

The LPPS-SL series sensor is made from industrial duty materials for resistance to dust, temperature, shock, and vibration.
