Available. The Sick WL280-2P2431 is a compact photoelectric retro-reflective sensor designed for precise object detection in industrial automation applications. Operating within a sensing range of 0.01 to 15 meters, it utilizes a visible red LED light source to detect objects by measuring reflected light. The sensor features a rectangular housing measuring 23.5 mm in width, 74.5 mm in height, and 63 mm in depth, with a light spot size of approximately 260 mm at an 8-meter distance. It offers a PNP switching output and supports both light-on and dark-on switching modes, with a maximum output current of 100 mA. The sensor operates within a supply voltage range of 10 to 30 V DC and has an IP66/IP67 protection rating, ensuring durability in harsh industrial environments. A potentiometer allows for easy adjustment of the sensing range. The package includes a mounting bracket (BEF-W280) and a reflector (P250) for straightforward installation.
