The W34 photoelectric sensor family features a durable plastic housing in ABS. All configuration components for the sensor are protected by a durable cover, allowing these sensors to be used in outdoor areas. The housing in die-cast zinc (W24-2) is recommended especially for tough and extreme ambient conditions.
A variety of other features are also available including, adjustable time delay, alarm output, test input, and DC voltage and universal AC/DC voltage. These provide additional flexibility and reduce the number of part numbers needed.
The W34 family includes background suppression proximity, retro-reflective and through-beam sensors. The background suppression proximity sensors are characterized by a long sensing range and immunity to ambient light.

Applications

High operating reserve at a long sensing range of retro-reflective and through-beam sensors ensures reliable operation
Variants with DC voltage and universal AC/DC voltage provide installation flexibility
