Infrared Proximity Contactless Button
Tutti i prezzi sono IVA inclusa
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.
*NOTE* As of 3/1/2022, the new version of this product has an operating voltage range of 12-24VDC (Used to just be 12V).
