Balluff BOS50K-PSV-RH12-S4 Diffuse Photoelectric Sensor

Balluff BOS50K-PSV-RH12-S4 is a compact diffuse-reflective photoelectric sensor with background suppression (order code BOS0156). It measures 28.5 x 80.5 x 62 mm and uses a red LED to detect objects by diffuse reflection, with a sensing range of 200–2000 mm and a 60 x 60 mm light spot at the rated range. The device provides a PNP normally open output via a 4-pin M12x1 connector, powered from 10–30 V DC, and features a glass sensing surface in a PC housing. Balluff lists CE, UKCA, and cULus approvals and WEEE compliance for this model. Typical applications include presence/position detection on conveyors, packaging lines, and assembly equipment, where background suppression helps discriminate foreground parts from the background.
