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. 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 below) Resources * Datasheet https://elecena.pl/product/22724986/infrared-proximity-contactless-button 2023-03-07 https://elecena.pl/product/22724986/infrared-proximity-contactless-button 2023-12-27 https://elecena.pl/product/22724986/infrared-proximity-contactless-button 2024-09-19 https://elecena.pl/product/22724986/infrared-proximity-contactless-button 2024-11-29 https://elecena.pl/product/22724986/infrared-proximity-contactless-button 2024-11-30 https://elecena.pl/product/22724986/infrared-proximity-contactless-button 2025-04-10 https://elecena.pl/product/22724986/infrared-proximity-contactless-button 2025-11-28 https://elecena.pl/product/22724986/infrared-proximity-contactless-button 2025-11-29
