SICK WL9G-3N2432 PHOTOELECTRIC SENSOR
Product Overview
The SICK WL9G-3N2432 is a compact industrial photoelectric sensor from SICK’s W9 series, designed for reliable object detection in automated production systems. It uses a retroreflective sensing principle with autocollimation optics and a visible red PinPoint LED to detect objects, including transparent materials, when installed with a compatible reflector.
With a maximum sensing range of 5 metres, a 10–30 V DC supply and an NPN switching output, the sensor is suitable for conveyor systems, packaging equipment, product counting and industrial inspection. Its compact housing and IP66, IP67 and IP69K enclosure ratings make it suitable for demanding industrial environments.
