SICK WL27-3P3402S13 Photoelectric Sensor

The SICK WL27-3P3402S13 is a RAY26 reflex array retro-reflective photoelectric sensor from SICK that detects objects by receiving light reflected from a reflector. Optimized for use with PL80A reflectors, it achieves sensing distances up to 4.5 m under typical conditions. The device provides a PNP output and runs on 10–30 V DC, with a 4‑pin M12 cable connection for straightforward installation. Key features include a single teach-in button, AutoAdapt for automatic adjustment to varying target reflectivity, and a visible red PinPoint LED for status indication, along with a light-band design for reliable edge detection. Typical applications encompass detecting transparent, perforated, shiny, or edge-tolerant targets on packaging, assembly, and material-handling lines. Part number 1046538 identifies this WL27-3P3402S13 model within the SICK catalog.
