The SICK WLG4S-3P2232VS03 is a compact, stainless-steel retro-reflective photoelectric sensor with a visible red PinPoint LED (650 nm). It supports object detection up to 5 meters without a reflector using autocollimation optics. The sensor features a lockable teach-in button, a rugged IP66–IP69K washdown-ready housing, fast response (< 0.5 ms), and a PNP output with light/dark switching, making it ideal for demanding hygienic and transparent-object detection applications.
