1 year warranty
The SICK WL12G-3O2431 is a compact retroreflective photoelectric sensor from the W12G series, designed for reliable detection of objects including transparent materials in industrial automation applications. This sensor utilizes autocollimation principle with polarization filters to detect objects at distances up to 4 meters when used with the PL80A reflector. It features visible red LED light source operating at 640 nm wavelength and provides selectable light/dark switching modes via control wire. The sensor is equipped with an 11-turn potentiometer for precise sensitivity adjustment and offers fast response time of 330 microseconds with switching frequency up to 1500 Hz. Its robust metal housing is rated IP66/IP67/IP69K for harsh industrial environments, and it operates across a wide temperature range from -40°C to +60°C, making it suitable for conveyor systems, material handling, assembly lines, robotics, and automated machinery applications.
