SICK WTB12-3P2460S04 Through-Beam Photoelectric Sensor

Compact SICK WTB12-3P2460S04 Photoelectric Sensor (W12-3 family), part number 1057942, packs a background-suppression detector into a rectangular 15.6 x 48.5 x 42 mm housing with a 4‑pin M12 A‑coded connector and a 2 m cable. It operates on 10–30 V DC with a typical current draw of 55 mA and less than 5 Vpp ripple, and it provides a PNP switching output with light/dark functionality for loads up to 100 mA. The emitter uses a PinPoint LED, delivering visible red light at 850 nm with a light spot about 7 mm at 300 mm. The sensing range spans 15 mm to 340 mm (preset to 300 mm for targets with ~90% reflectivity), enabling reliable detection on small parts and in cluttered environments. With a fast response time ≤ 330 µs and a switching frequency up to 1,500 Hz, it suits high-speed packaging and conveyor applications. Built for tough industrial settings, the housing is rated IP66/IP67/IP69K, and the unit weighs roughly 200 g. This sensor is well-suited for compact machine integration, part presence detection on conveyors, and small-assembly sensing where pinpoint accuracy and rapid, repeatable switching are essential.
