IR Obstacle Avoidance Proximity Sensor E18-D80NK Description: 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. Specification: Diffuse reflective type Light source: Infrared Sensing range: 3cm to 80cm (depends on obstacle surface) Input voltage: 5VDC Current consumption: 100mA Dimension: 1.7cm (D) x 4.3cm (L) Type :DC 3 Wire NPN-NO (Normal Open) Sensory distance regulator and output LED indicator Control signal level: High2.3V≤Vin≤5V Low-0.3V≤Vin≤1.5V
