WL4-3F3130

The WL4S-3F3130 is a miniature retro-reflective photoelectric sensor with autocollimation optics, enabling detection without a reflector at very close ranges. It uses a visible red PinPoint LED and features PNP dark-switching output. Its slim, rectangular housing and IP67 rating make it ideal for compact industrial applications.
