SICK Retroreflective Photoelectric Sensor, Rectangular Sensor, 0.01 → 5 m Detection Range

The WLG4S-3 INOX photoelectric retro-reflective sensor in Wash-down design combines rugged watertight IP 69K stainless steel housing with "best-in-class" optical functionality. Designed to detect transparent objects, the sensors also boast advanced features such as continuous adjustment of switching thresholds. They can be relied upon for long-term service in critical applications in the food and beverage, pharmaceutical, solar, and electronics industries.

These space-saving miniature sensors are able to withstand the most aggressive cleaning agents and disinfectants thanks to a teach-in membrane that is 100% watertight and pin-cast M12 connections.
