E18-D80NK Photoelectric Sensor Module (Infrared Obstacle Avoidance Proximity Switch)




The E18-D80NK Photoelectric Sensor Module is a reflection type sensor which integrates transmitting and receiving infrared beams function. It is a photo-detector on the proximity switch that detects any reflections of the light. This is an extremely easy to use sensor that consists of an IR transmitter and receiver pair in one module.  The IR transmitter emits IR light and the IR receiver detects the IR light that is reflected off objects.
