SICK WTE15-P1111 Photoelectric Proximity Sensor

The SICK WTE15-P1111 is a compact cylindrical photoelectric proximity sensor from the W15 family, designed for reliable presence sensing in tight spaces; it features an M18 x 1 threaded body and measures roughly 16.2 mm in diameter, 48.5 mm long, and 31.9 mm deep, powered from 10 to 30 V DC with a Class 2 energy profile and a typical current draw around 100 mA. It emits infrared light at 950 nm with a focused beam of about 4.5 degrees and a light spot roughly 50 mm in diameter at the far sensing distance, with the sensing range adjustable via a five-turn potentiometer and up to 350 mm for a standard white target with 90% reflectivity (DIN 5033). This combination makes the WTE15-P1111 well suited for applications such as presence/absence detection on conveyors, packaging lines, and machine assemblies, where a compact, DC-powered sensor is required; its rugged M18 mounting and compatibility with standard industrial wiring support straightforward integration into existing control schemes.
