Upgrade your interface with the Infrared Proximity Contactless Button. Ideally suited for public spaces, medical environments, or any setting where hygiene is a priority, this sensor replaces standard mechanical push buttons with a clean, touch-free solution. Just wave your hand near the sensor to trigger the switch. No physical contact required! Smart & Responsive Unlike basic sensors that can flicker due to ambient light interference, this button features a built-in microcontroller that filters out noise, ensuring reliable operation every time. It also provides clear visual feedback via a Red/Blue LED ring that illuminates to indicate the device is powered and changes color instantly when a "touch" is registered. Fully Adjustable Every installation is different, so we've made this sensor adaptable via two potentiometers located on the back of the device: * Read Range (3-15cm): Adjust how close a hand needs to be to trigger the switch. This is critical for preventing accidental triggers from passersby while ensuring intentional waves are caught. * Open Time (0.5s - 20s): Control how long the relay remains active after triggering—ideal for magnetic door locks that need to stay open for a few seconds or for timed signal pulses. Industrial Build The electronics are encased in a durable, Fire and IR-resistant housing designed to mount easily through standard panels and surfaces. We have also updated the power input to a wide 12-24VDC operating range, making it compatible with most standard security and industrial power systems. https://elecena.pl/product/19525578/infrared-proximity-contactless-button 2021-09-24 https://elecena.pl/product/19525578/infrared-proximity-contactless-button 2022-02-22
