The SICK WL12-2P430 is a photoelectric retro-reflective sensor with a 5 m sensing range, built for object detection on conveyors, packaging lines, and material-handling stations where a reflector can be mounted opposite the emitter. The 5 m range covers most single-lane conveyor spans and pallet-detection zones without needing a separate receiver. It operates on 10…30 V DC with a PNP light/dark switching output rated up to 100 mA, so it interfaces directly with standard PLC digital inputs — no level-shifter or relay interface needed. The IP67 enclosure means the optics and electronics survive washdown cycles and dusty environments common in food-and-bev and logistics centers. Connection is via an M12 4-pin male connector — a standard industrial quick-disconnect that mates with pre-wired cordsets or panel-mounted receptacles, keeping field-replacement time under a minute.
The rectangular housing (15 x 49 x 41.5 mm) fits tight spaces on conveyor frames or machine guarding brackets. Operating temperature from -40 to 60 °C covers cold warehouses and heated production floors without derating.
