SICK WL8-P1131S04 Photoelectric Sensor (6048889)

The SICK WL8-P1131S04 is a compact, high-speed photoelectric retro-reflective sensor designed for reliable detection of fast-moving objects over distances up to 4 meters. Featuring autocollimation (coaxial optics) for precise alignment and a visible red LED light source, this sensor is ideal for applications requiring fast, accurate detection with minimal setup.

Supplied with a P250 reflector and mounting bracket, the WL8 series combines ease of installation with robust IP67 protection for industrial automation environments.
