Details
Ready to use in zone 2 and 22 Ex areas thanks to device category 3G / 3D
W27 photoelectric sensors are suitable for use in a harsh industrial environment. The powerful sensors are designed to withstand strong vibrations, shocks or strong temperature fluctuations. The devices offer a high operational reliability even with reflections. There are also ready-to-install sensor variants with additional protective metal housings that meet the requirements of device categories 3D and 3G according to ATEX. This enables these variants to achieve a mechanical stability that is unmatched by standard sensors.
