WTB250-2P2441 Photoelectric Proximity Sensor 500mm PNP IP67 | SICK

The Original New SICK WTB250-2P2441 (6044682) is a compact photoelectric proximity sensor from the W250-2 series, designed for reliable object detection using background suppression. Its visible red BrightLight LED and 2-turn potentiometer with an easy-to-read positioning indicator simplify alignment and commissioning, while the rectangular ABS housing ensures durability in industrial environments. The sensor reliably distinguishes target objects from the background at a sensing range of 150 mm to 500 mm, making it suitable for automation lines, packaging machinery, robotic positioning, and material handling systems.
