Does anyone know where i can get photoelectric switches that can be used in ATEX Zone 21 with the sensing rang >= 400mm for diffuse type? Many thanks

I had hard time trying to get these types of photosensors until I started using KEYANCE photosensors; they are reliable and easy to get, just go to KEYANCE web page.

SICK, Inc. has a number of ATEX rated sensors.
