Wenglor HO08PA3 Reflex Sensor with Background Suppression

These sensors detect distance by measuring angles. They are particularly good at recognizing objects in front of any background. The color, shape and surface characteristics of the object have practically no influence on sensor switching performance. Also these sensors don’t influence each other if their light spots are pointed onto the same spot or against each other.
