The BOS 12M-PS-PR10-S4 is a retroreflective photoelectric sensor with a PNP normally open output, operating at a rated distance of 3000mm and detecting via a reflector target. Its housing is brass with a nickel-plated finish and a PMMA sensing surface, rated IP67 for use in demanding industrial environments, and it connects via an M12x1 4-pin male connector. With an operating voltage range of 10–30 VDC and switching frequency of 1000 Hz, it is suited to automation panels and machine builds requiring reliable object detection with M12 nut mounting.
