Overview
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.
