More info

Detail about E18-D80NK

This is an infrared distance switch. It has an adjustable detection range, 3cm - 80cm. It is small, easy to use/assemble, inexpensive. Useful for robot, interactive media, industrial assembly line, etc.This is an Infrared Transmitter and receiver which together make up a photoelectric sensor. The sensor has a long detection distance, and has less interference by visible light because it uses modulated Infrared light. This sensor has a screwdriver adjustment to set the detected distance, then gives a digital output when it senses something within that range. This sensor does not return a distance VALUE. See the photo on right: Connections are:

The technology behind this effective distance sensor is Modulation of Infrared Light. The receiver is sensitive only to infrared light and only when it receives the correct signal. Therefore it is not very sensitive to ambient light compared to plain Infrared detectors.
