Sensor (WES) | Warner Electric

The WES is a contactless monitoring solution, providing reliable detection of the smallest strokes, especially on spring applied brakes with noise damping systems. With no sensitive mechanical parts, it outmatches the electromechanical solutions by far regarding functional safety and lifecycle expectance.

The WES features a temperature compensated sensor able to operate from -40°C up to 105°C. It offers 3 types of outputs. An NPN type (Version 1) with an integrated pull-up resistor that simplifies the integration in almost all PLC based installations, a highly isolated SSR relay type NC and NO outputs (Version 2) that provides backward compatibility with almost all dry contact switches of the market, and an optional analog ratiometric output (Version 3) which offers a real time wear detection that measures the brake air gap.
