SICK WT27-2S030S14 High Performance Photoelectric Sensor

The SICK WT27-2S030S14 is a compact, high-performance diffuse-reflective photoelectric proximity sensor from the WT27 family. Its rectangular housing measures 24.6 mm wide by 80 mm high by 53.5 mm deep, delivering a rugged, compact footprint for tight spaces. The sensing range spans from 100 mm to 1,000 mm, allowing detection of mid- to long-range targets in conveyors, packaging lines, and automation cells. It emits visible red light from a LED light source, and at a distance of 500 mm the light spot diameter is 15 mm, enabling predictable targeting on reflectivity-rated surfaces. The device is cataloged as WT27-2S030S14, with part number 1015709. Its sensing principle is diffuse reflection—detecting an object by the light reflected off its surface, with standard reference cases defined for surfaces around 90% reflectivity per DIN 5033. The WT27-2S030S14 variant is noted to have an average service life of about 100,000 hours at an ambient temperature of +25°C. With its compact form factor and 100–1,000 mm range, this sensor provides a reliable, space-efficient solution for object presence detection in demanding industrial environments where simple, robust optics are required.
