SICK WE140-2P430 Through Beam Photoelectric Sensor

The SICK WS/WE140-2P430 Through-Beam Photoelectric Sensor is a compact long‑range detection solution for industrial lines, using a paired emitter and receiver to sense beam interruptions up to 16 meters away. Its rectangular housing measures 11 mm wide by 31 mm high and 20 mm deep, and it uses a 4‑pin M8 connector for a 10–30 V DC supply with a PNP output configuration. The 6024791 variant is designed for rugged manufacturing environments, delivering reliable presence sensing across conveyors, pallet detection, and packaging applications where objects pass between aligned units. With straightforward installation on machine frames or fixed supports, this through‑beam sensor provides consistent signaling when a beam is broken, supporting precise machine control, line automation, and workflow verification without sensitivity to target color or surface Finish.
