The SICK WL27-3P2431 is a compact retro-reflective photoelectric sensor equipped with a dual-lens system for detecting objects at very short distances—even without a reflector. It emits a visible red LED beam and delivers precise, high-speed detection in a robust ABS housing rated IP69K. The sensor supports PNP light/dark switching output, features a multi-turn potentiometer for fine sensitivity adjustment, and includes comprehensive electrical protection, making it well suited for demanding industrial environments.
