Due to their high performance reserve, these devices are used for reliable detection even with heavy soiling in category 3G and 3D applications. The product spectrum encompasses familiar operating principles such as throughbeam photoelectric sensor, retro-reflective photoelectric sensor or scanner with background suppression. The temperature class for explosive gas areas is T4; for explosive dust areas it is 90 degrees Celsius.

Scanner with adjustable background suppression through multiturn potentiometer
Reliable detection of light and dark, as well as inclined or sloped surfaces
Fast connection through Ultra-Lock fast locking
Complementary switching outputs for optimal adaptation to the application
Warning output for increased availability
