Our light sensors with background suppression detect objects within a set switching distance without being affected by the reflective background. And this is almost independent of the color and surface of the object. Object and background can be reliably distinguished, especially since these light sensors are characterized by their low gray value shift and hysteresis. Since the transmitter and receiver are housed in a space-saving housing, our light sensors are easy to install and quickly align. The clearly visible light beam of the red light and laser versions also supports you. With teach-in or via potentiometer, you can easily adjust many sensor versions. Versions with a fixed switching distance are also available.
