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 (especially in this day and age!).

This button includes a built-in microcontroller to handle interference or noise, a red/blue status LED that gives the user visual feedback that a "touch" has been registered, and two potentiometers on the back of the device that 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 a Fire/IR resistant package that easily mounts through most panels and surfaces.


  • Built-in micro controller for decoding infrared signal to avoid interference from the noise.
  • Bi-color status LED (Power on: Red/ Proximity: Blue).
  • Adjustable proximity range: 3~15cm (Default: 15 cm)
  • Support adjustable opening time 0.5~20 Sec. (Default: 0.5 Sec.) or latched ON or OFF output.
  • Polycarbonate fire & UV proof material enclosure.
  • 39.7mm Diameter (full dimensions in datasheet below)
