SICK WL100-P1422 Photoelectric Sensor

The SICK WL100-P1422 is a compact photoelectric sensor from the W100 family that operates as a retro-reflective type, using a visible red LED light source to detect objects in a short-range sensing field when paired with a reflector. It provides a 3‑wire output with a PNP switching configuration and ships with a 2 m cable, enabling straightforward integration into compact automation layouts. The sensor’s detection geometry includes a light spot size of approximately Ø200 mm at a 2 m distance, helping users gauge the effective sensing area and align reflectors accordingly. A built-in adjustment potentiometer allows threshold tuning to accommodate varying surface contrast and ambient conditions, supporting reliable switching in production environments. Power is supplied within the WL100 standard range for such devices, and the unit is designed for retrofit-friendly installation on small-form-factor applications, including presence detection and positioning checks on conveyors or in packaging lines, where a miniature retro-reflective sensor is advantageous. As part of the SICK W100 family, WL100-P1422 emphasizes a compact form factor, consistent 3‑wire PNP outputs, and straightforward wiring, making it a suitable choice when a robust, easy-to-commission reflective sensor is required in tight spaces.
