Diffuse reflective sensor O-21
OT21-NS-0.3T3
Article Number: 212984
Energetic diffuse reflective sensors are economical sensors for detecting objects in which transmitters and receivers are located in one housing. They evaluate the energy of the reflected sensor light from objects. The working distance and the brightness of object and background influence object detection. Bright objects against a dark background can be detected well with energetic diffuse reflective sensors.
