The high-performance light barriers were specially developed for areas of application in which traditional photo-electric sensors reach their limits. Extreme dirt resistance and a long range make them particularly suitable for most difficult applications. The system's high power guarantees excellent penetration, even in the case of extreme contamination. Chips, dust, flour, oil or muddy water are no longer an obstacle. They are perfectly suitable for use in the timber and paper industry, in car wash systems, for control bulk material, in elevators, for outdoor gate control, in the food processing industry and in many other applications.
