SICK WL12-2B560 Photoelectric Sensor

SICK WL12-2B560 is a compact photoelectric retro-reflective sensor (part no. 1016080) designed for dependable object detection on automation lines. It operates from 10 to 30 V DC, draws about 30 mA, and uses a visible red LED light source with a rectangular housing measuring 15 mm x 49 mm x 41.5 mm. The device features a M12, 5-pin connection, adjustable via a potentiometer, and is intended to be used with reflector PL80A for reflective sensing. Its sensing range spans 0 to 3.5 m for reliable switching, with a maximum achievable distance of 4 m under favorable conditions. The sensor offers light/dark switching selection (0 V or open-circuit yields light switching; UV input yields dark switching) and has a fast response time of ≤ 330 µs, suitable for high-speed pick-and-place or conveyor applications. Built for challenging environments, it carries an IP67 enclosure rating, a zinc die-cast metal housing, and PMMA lens, ensuring rugged operation from -40 °C to +60 °C (with storage from -40 °C to +75 °C) and low supply ripple (<5 Vpp). Typical industrial uses include presence or position sensing where a reflector is installed, making the WL12-2B560 a precise, reliable choice for compact retro-reflective sensing on production lines and material handling systems.
