Sick Retroreflective Photoelectric Sensor, Rectangular Sensor, 0.1 → 1.8 m Detection Range

The W27 family is designed for harsh industrial environments where it copes easily with heavy vibrations, shocks and extreme temperature fluctuations. The photoelectric proximity sensor is a leader in its class, especially through its reliable detection at long ranges. The retro-reflective and through-beam versions reduce downtime due to high operating reserves. A diverse range of features further enhance application-specific functionality including, Teach or potentiometer adjustment, time delays, front lens heating, IO-Link, ASi, and universal voltage DC or AC/DC.

A sensor with Pinpoint LED or a laser photoelectric proximity sensor is available for detection of small targets.

Intense visible red emitter LED with consistent light spot for Pinpoint versions
Long sensing ranges with IR LED achieve up to 2500 mm
