Principle Of PCAP Design
The typical design principle of PCAP uses mutual capacitance measurement. AMT adopts self-capacitance measurement instead and can successfully reduce the noise interference caused by liquid. However, while self-capacitance measurement could avoid false signals, conductive substances in many liquid forms could still affect the touch function. So when operating touch under the influence of liquid, a signal response might still be triggered within the liquid range.
To tackle this problem, our R & D team performed meticulous adjustment on the structure, hardware, as well as firmware of PCAP touch buttons. We are happy to share that conductive substances in liquid no longer cause problems for our touch button products! When there is liquid on the surface of the PCAP touch buttons, the touch operation can still be performed like normal!
Water Resistant PCAP Touch Button
AMT water-resistant PCAP touch buttons are great for bathroom control panels. One-finger operation is possible when water, detergent, or soapy water is sprayed on the PCAP touch product. Furthermore, AMT PCAP touch buttons can work with 2.8mm cover glass, support up to 22 keys, and we can add LED indicator lights based on customer needs.
