E18-D80NK IR Obstacle Avoidance Proximity Sensor E18-D80NK adjustable IR Infrared Proximity Sensor Switch features an IR sensor.

The E18-D80NK adjustable IR Infrared Proximity Sensor Switch features an IR sensor that can measure distance between 3 to 80 cm. It features an easy to mount chassis, making prototyping much simpler.

The infared proximity switch module is a reflection-type photoelectric sensor which integrates transmitting and receiving infared beams function. Infrared proximity switches work by sending out beams of invisible infrared light.

A photodetector on the proximity switch detects any reflections of this light.

These reflections allow infrared proximity switches to determine whether there is an object nearby.
