The SICK WTR2-P511S20A01 ZoneControl photoelectric sensor is a compact infrared device designed for zone-based object detection on conveyors, packaging lines, and other industrial equipment. It operates on 18–30 V DC and offers selectable switching outputs (PNP or NPN) with the PNP output on pin 4 and the NPN output on pin 2 for straightforward PLC interfacing. The sensing range spans 300 to 900 mm, with a light spot of about 40 mm at 900 mm, and adjustment is via potentiometer. It provides up to 100,000 hours of service life at 25 C, reflecting its suitability for continuous operation in typical factory environments.
