E18-D80NK Adjustable Infrared Sensor Switch 5V DC 10-80cm NPN NO

The E18-D80NK Adjustable Infrared Sensor Switch 10-80cm is a set of transmitter and receiver in one of the photoelectric switch sensor.  The sensor has a detection range of 10-80cm. The detection distance can be adjusted according to the demand.

The Adjustable Infrared Sensor Switch is small, easy to use, inexpensive, easy to assemble, and can be widely used in a robot to avoid obstacles, interactive media, industrial assembly lines, and many other occasions.

The switching signal output differs in accordance with the obstacles. It remains high when no obstacles and remains low when there are obstacles. 

Features :

• Diffuse reflective type.
• Digital output.
• Adjustable detection distance.
• Low consumption.
• Compact size.
• Range: 10 - 80cm adjustable
• Power supply: 5V
• Current: 100mA
• Red: +5V; Yellow: Signal; Green: GND

Package Includes :

1 x E18-D80NK Adjustable Infrared Sensor Switch 5V DC 10-80cm NPN NO
