The SICK WL23-2P2430 is a compact retro-reflective photoelectric sensor featuring a dual-lens system and visible red LED illumination. It offers reliable detection across ranges from 0.1 m to 10 m (typically 0.3 m to 7 m with a PL80A reflector) and delivers complementary PNP light/dark switching output. Housed in a robust ABS enclosure with IP67 protection, it includes built-in circuit protections and connects via a 4-pin M12 male connector, making it ideal for industrial automation tasks requiring flexible, dependable object sensing.
