The sensors are developed for all category 3G and 3D applications. With their small dimensions, they fit even in constrained spaces. The sensors and the protective housing are made of stainless steel and are also suitable for demanding operating conditions. Currently available are retro-reflective photoelectric sensors and scanners with background suppression. The temperature class for explosive gas areas is T4; for explosive dust areas it is 70 degrees Celsius.

Diffuse reflection light scanner with visible red light and adjustable background suppression
Stainless steel device housing and protective housing
Exact scanning range adjustment via 8-turn potentiometer
Very good black/white behavior and reliable switching nearly independent of the object or background properties
Fast alignment through brightVision
