AT42QT2100-MUR

The AT42QT2100-MUR is a compact, low power, single-channel analog output Touch Sensor with a robust and reliable OTP signature configuration. It is designed specifically for use in industrial and consumer electronics applications, offering a robust and accurate solution for sensing applications. The AT42QT2100-MUR offers a unique combination of features such as excellent signal stability, low power consumption, and the ability to be used in hostile, electrical and temperature conditions.

The primary application area of the AT42QT2100-MUR is in industrial applications where reliable and accurate touch sensing is required. It is designed to be used in the presence of high voltage and temperature environments, making it suitable for use in machining, stamping, and assembly operations. The AT42QT2100-MUR can also be used in consumer and medical products such as blood pressure monitors, PLCs and HMI displays.

The AT42QT2100-MUR functions by sending a high frequency AC signal through the medium in which it is mounted. When an object touches the device, a capacitance is created and an interrupter is sensed by the AT42QT2100-MUR. The current is then amplified and sent to an analog output pin and to the microcontroller. The microcontroller then interprets the signal and activates the appropriate response. This response can be LED lighting, vibrating motors, or other alarms and responses.

The AT42QT2100-MUR is designed to operate under a wide range of conditions, including both hostile and benign environments. It is immune to false triggers caused by dirt, grease, or liquids, and can operate in temperatures between -40°C and +85°C. The sensitivity of the device can be easily adjusted using the OTP signature. Additionally, the power consumption is extremely low, allowing it to be used in battery powered applications without serious compromise of battery life.

In summary, the AT42QT2100-MUR is a robust and reliable touch sensor which offers a unique combination of features. Its low power consumption, robust design, and wide temperature range make it ideal for use in industrial and consumer electronics applications. Its analog output pin ensures reliable and accurate response in all conditions, allowing for the detection of even the smallest touches.
