Infrared Proximity Contactless Button - ABT-30IR

This IR proximity contactless button makes for a good replacement for typical push buttons in situations where touching the button isn't required or desirable. This button includes a built in microcontroller to handle interference or noise, a red/blue status LED gives the user visual feedback that a "touch" has been registered, and two potentiometers on the back of the device allow you to adjust the read range from 3-15cm and adjust the "open time" from 0.5 to 20 seconds.

All this is encased in an durable package that easily mounts through most panels and surfaces.
