Sick WT27L-2S830A01 Through-Beam Photoelectric Sensor

Sick WT27L-2S830A01 is a compact laser-based photoelectric sensor from SICK (part no. 1016360) designed for reliable object detection in tight spaces. The rectangular housing measures 24.6 mm wide by 80 mm high by 53.5 mm deep, and it detects targets from 100 mm to 800 mm away using a visible red 650 nm laser (laser class 2) with a light spot roughly Ø2 mm at 400 mm. The sensor employs background suppression to improve detection against backgrounds and offers sensitivity adjustment via a potentiometer for fine-tuning. It accepts 24 V to 240 V on both DC and AC supplies, with a power consumption under 2 VA, making it compatible with standard industrial power rails. These characteristics support applications such as part counting on conveyors, packaging verification, and automation line monitoring where compact form factor and reliable sensing are required.
