WTB11-2P2461 Photoelectric Proximity Sensor PNP 1100mm IP69K | SICK

The Original New SICK WTB11-2P2461 (1044442) is a rectangular photoelectric proximity sensor from the W11-2 series, designed for reliable object detection using background suppression technology. It detects objects within a maximum sensing range of 30 mm to 1,100 mm, delivering consistent performance independent of background interference. The visible red PinPoint LED produces a precise Ø 6 mm light spot at 200 mm, simplifying alignment. Housed in a rugged ABS enclosure rated IP66/IP67/IP69K, the sensor is built for demanding industrial environments including washdown applications. It provides a PNP complementary output with selectable light/dark switching and is adjusted via a 5-turn potentiometer.
