SICK WL27-3P3402S17 Through-Beam Photoelectric Sensor

SICK WL27-3P3402S17 is a retro-reflective photoelectric sensor from the RAY26 Reflex Array family that detects targets by reflected light, with PL40A listed as the reflector for this model. The compact rectangular housing measures 24.6 mm wide by 80 mm high by 54.2 mm deep and emits a visible red beam from a PinPoint LED, supporting detection of objects as small as 5 mm within a sensing range of 0 to 1.5 m (0.5 to 1.5 m to the reflector). It features single teach-in adjustment, AutoAdapt, and a light-band capability, and is specified to handle challenging targets such as transparent, perforated, uneven, and shiny objects, or items with positional tolerances, making it suitable for small-part sensing, packaging, and material-transport workflows where a compact retro-reflective sensor is advantageous.
