MSI-LWH series linear displacement sensor with resistive output
Universal resistive position sensor is designed for direct and accurate measurement of an object’s position during linear displacement or for providing feedback from the object.
Durability rating of 30 million cycles.
Maximum traversing speed 5 m/s.

Operating principle
The sensor consists of a profile with a spring-return plunger. Inside the sensor, the plunger is mechanically linked to a resistive layer deposited on a fiberglass (PCB) substrate via a wiper.
The output signal is generated according to the linear voltage divider principle, where the output voltage changes linearly in direct proportion to the wiper travel across the resistive layer.
