MSI-LWG series linear position sensor with resistive output

Rod-style sensor with two rod ends and extending rod 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 displacement speed 5 m/s.

Operating principle

The sensor consists of a cylinder with a spring-return (or free) plunger. Articulated rod ends are installed on each side of the sensor, allowing the sensor and the plunger to be rigidly connected to the controlled part of the machine. 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.
