The SICK WL9-P135 is a photoelectric reflex switch with a PNP output, switching mode selectable between light-on and dark-on, and a cable connection. It operates on a 30 V DC supply and provides a maximum sensing distance of 3 m (3000 mm). The housing measures 22 × 14 × 63 mm.
The 3 m sensing range suits applications like presence detection on conveyors or through small gaps in packaging lines. The PNP output and cable connection simplify wiring into standard 24 V DC control systems.
