SICK WTB8-P1131S09 Fiber Optic Photoelectric Sensor

SICK WTB8-P1131S09 is a compact W8 miniature photoelectric sensor with background suppression, designed for reliable part detection in tight spaces. It senses objects from 40 to 300 mm and uses a red-emitting light, with a PNP normally‑open output to simplify wiring into common automation circuits. The unit ships with a Würth cable assembly and employs the standard W8 housing with M3 threaded mounting holes for flexible installation. It carries an IP67 rating for dust and water protection and offers a fast 0.5 ms response time, suitable for high‑speed inline sensing on conveyors and in packaging applications. This variant is ideal for detecting small parts against complex backgrounds, where background suppression helps ignore surrounding material while delivering consistent triggers in industrial environments.
