Balluff BOS0004 is a compact diffuse photoelectric sensor in a cylindrical 8 mm housing (BOS 08M-PO-RD11-S49), measuring Ø8 x 57.5 mm with a PNP normally closed (NC) output. It operates on 10–30 V DC, uses a PMMA sensing surface, and emits a red LED for status indication with a divergent beam for short-range detection from 0 to 55 mm. The device features a robust brass, nickel-plated housing and an M8x1 3‑pin connector for easy wiring, making it suitable for tight spaces on conveyors, pick-and-place cells, and other compact automation applications. This Balluff sensor is documented as cULus approved for the US, with regional variants offering additional certifications on other Balluff portals.
