WL4S-3F3130

The WL4S-3F3130 is a compact retro-reflective photoelectric sensor with autocollimation optics, allowing detection without a reflector at very close range. It uses a visible red PinPoint LED and features PNP dark-switching output. Its slim, rectangular housing (12.2 mm × 41.8 mm × 17.3 mm) and IP67 rating make it ideal for space-constrained industrial applications.
