The SICK WLG4S-3P3132 is a compact retro-reflective photoelectric sensor with autocollimation optics, enabling detection even without a separate reflector. It uses a visible red PinPoint LED, offers a slim rectangular design, incorporates a single teach-in button for easy configuration, and supports AutoAdapt for stable detection of transparent objects. The sensor delivers fast PNP light-switching performance with built-in protection, all in a durable IP67-rated housing suitable for industrial environments.
