SICK WT18-3P430 Photoelectric Sensor With Mount

SICK WT18-3P430 is a compact diffuse-reflective photoelectric sensor with background suppression, optimized for reliable presence/absence detection on conveyors and packaging lines across a 50–600 mm range. Powered from 10–30 V DC and drawing about 40 mA, it provides a PNP switched output and uses a 675 nm visible red LED in a 17.6 × 75.5 × 33.5 mm rectangular head with an M12 4-pin connection. Range is adjustable via a four-turn potentiometer within the 50–600 mm switching distance, and the unit ships with mounting hardware for quick installation in standard automation setups. Its 1:1 light/dark switching and background suppression support detecting parts with varying reflectivity in compact spaces, making it suitable for small-part detection on assembly lines and in conveyor-packaging applications.
