Diffuse reflective sensors O-20
LLT 21 K 70 P3
Article Number: 207166
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.
- Long ranges with a small design
- High resolution
- Visible red light with small light spot
- Sensitivity is adjustable
- LED switching status display
