There are many kinds of touch sensors on the market, but every one of them has some unique features that make it stand out from the crowd. TouchKey 3 click is equipped with seven advanced capacitive sensors, based on the proprietary QTouch® technology. Besides quite a large number of QTouch® capacitive sensor channels, TouchKey 3 click also offers some additional features, such as the Adjacent Key Suppression (AKS®), a technology that ensures correct button press, even when the touch sensing pads are placed close to each other.
With its many sensing channels and their advanced sensing technologies, TouchKey 3 really stands out from the crowd. It can be used as a multi-button control pad for various embedded applications, replacing mechanical buttons, which are typically prone to malfunctions, with elegant and durable touch sensing pads. Since it can detect touch through 5mm thick layer of plastic, TouchKey 3 is covered with a protective plastic coating, which makes the click board™ even more robust and wear-proof.
