WL4-3P3130

The SICK WL4-3P3130 is an ultra-compact retro-reflective photoelectric sensor that uses a visible red PinPoint LED and dual-lens optics with polarization filters for accurate detection. It offers a sensing range from 0.02 m to 3.5 m (up to 4.5 m max with a PL80A reflector), quick PNP light-switching output, and fast response in a sleek slim housing ideal for tight installations.
