The SICK WLG4-3P2132 is a compact retro-reflective photoelectric sensor that uses a visible red PinPoint LED light source at 650 nm to deliver reliable object detection from as close as 0.02 m up to approximately 3.5 m with standard reflectors. The light spot size at a 1.5 m distance is around 75 mm in diameter when used with a PL80A reflector. The housing is a small rectangular design with three-pin M8 connector options, and commissioning is streamlined with a single teach-in button and AutoAdapt functionality.
