SICK WL12-2P430 Photoelectric Sensor

The SICK WL12-2P430 Photoelectric Retro-Reflective Sensor is a compact, metal-bodied device that detects reflective targets up to 7 m away using visible red light. Its rectangular housing measures 15 mm × 49 mm × 41.5 mm and is built from zinc‑diecast metal with a PMMA optics window, rated IP67 for rugged industrial use. It provides a PNP switching output via a 4‑pin M12 connector and operates on 10–30 V DC with a typical current draw of 30 mA (supply ripple under 5 Vpp). Adjustment is performed with an integral potentiometer, and it is designed for use with the PL80A reflector for retro‑reflective sensing. The WL12-2P430 supports light/dark switching and offers a fast response time, typically ≤ 330 µs, suitable for high‑speed packaging and material‑handling applications. Operating temperature spans −40 °C to +60 °C, with storage tolerance to −40 °C to +75 °C, and its sturdy housing provides reliable performance in challenging environments.
