Measuring principle

Light Barriers and Active Infrared Detectors are optoelectronic sensors which detect persons an objects using light without any physical contact being established. The way in which they function is simple but effective.
Light Barriers respond to each interruption of bthe beam between the light transmitter and receiver. Active Infrared Detectors, on the other hand, detect an object as soon as the light reflected by the surface of the object is received. Once an object has been detected, the sensor generates a definded electrical output signal. Evaluation electronics and relay or transistor outputs are thus just as much a part of the sensor as the light transmitter and receiver. The applications of the two basic detection principles are very diverse. In order to do justice to this diversity, various different functional sensor types were developed from these two basic principles.

Application guidelines

Typical Applications
Detection of Hot Metal or Hot Product in a Rod Mill, Bar Mall, Rolling Mill, Plate Mill, Roughing Mill, Reversing Mill, Hot Strip Mill or other Steel Mill and Industrial Applications.
