It is available in several variants and is compatible with Quantum’s in-line capacitive sensors, making it an ideal solution for large touch screens, such as those found in retail kiosks, ATMs and POS systems.

Working Principle

At the heart of the QT60161-AS is Quantum’s patented Quantum-3 surface capacitive sensing technology. This technology allows the device to detect even the slightest touch, enabling sensitive and reliable operation. The device is designed to operate with a single or multiple in-line capacitive sensors. The touch controller integrates an advanced signal processing algorithm to distinguish between genuine touches and false touches. It sends out a variable electric field, which is used to detect changes in the electric field in order to determine where a touch has occurred. To further improve reliability, the controller can be configured to perform edge filtering, which helps to reduce false touches.

Conclusion

The Quantum QT60161-AS touch screen controller is a highly versatile, cost-effective solution for a wide range of touch screen applications. It is based on Quantum-3 surface capacitive sensing technology which provides reliable and accurate touch sensing and is capable of distinguishing genuine touch from false touches. It provides a powerful solution for large touch screens, such as those found in retail kiosks, ATMs and POS systems.
