SICK WL27-3P3402S13 Through-Beam Photoelectric Sensor

The SICK WL27-3P3402S13 (1046538) is a compact retro-reflective photoelectric sensor from the WL27 RAY26 Reflex Array family, housed in a rectangular enclosure measuring roughly 24.6 mm wide by 80 mm high by 54.2 mm deep. It emits a visible red beam via a PinPoint LED and supports quick setup through a single teach‑in button with AutoAdapt, offering a sensing range to a reflector of 0.5–4.5 meters with PL80A (0.5–4.5 m) or 0.5–2 meters with PL40A (0.5–2 m), for a maximum overall range of 4.5 meters. Designed to handle challenging targets, it detects transparent, perforated, uneven, and shiny objects and features a minimum detectable object size of 12 mm, along with a light-band feature that broadens sensing coverage across the target plane.
