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 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 a Fire/IR resistant package that easily mounts through most panels and surfaces.
Features:
- 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)

Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
