Pepperl+Fuchs MWC25M Radar Sensor Review: Specs and Uses of the 25 m CANopen Radar Sensor

The Pepperl+Fuchs MWC25M is a radar sensor that measures distance and speed for vehicles and machines. This review covers its specifications, features and uses.

Quick Verdict

Radar keeps working where optical sensors struggle, in dust, rain, fog and dirt. The MWC25M uses 122 GHz FMCW radar to measure distance from 0.5 to 25 m with 1 mm resolution and repeat accuracy, and speed from 0.1 to 80 m/s, at up to 200 Hz. A narrow beam under 12 degrees and a rotatable head make alignment easy. It speaks CANopen, is sealed to IP68 and IP69, works from -40 to 70 °C and supports safety functions up to PL c. At 180 g and 0.4 W it suits mobile machines. Pepperl+Fuchs lists it at $820.
