The FR 18-2 RM-PS-L4 is a retro-reflective photoelectric sensor with a brass, nickel-plated housing and a PMMA front screen, rated IP67 for use in demanding industrial environments. It detects objects at operating distances of up to 3000mm and provides a PNP switching output with a switching frequency of up to 1000Hz, operating from a 10-30 VDC supply. Connection is made via an M12, 4-pin metal plug, and the sensor includes a red LED interface for status indication. Its compact housing suits mounting in automation panels and machinery where reliable object detection is required.
