The QT110A-ISG capacitive touch sensor offers an attractive, cost-effective solution for a wide range of applications. This low power sensor is based on a patented capacitive touch sensing technology that can detect the presence of an object near the sensor surface. It offers an extremely low-power solution for selecting or controlling an output from the sensor.

The principle of operation of the QT110A-ISG is based on the change in the electric field around a conductor when a mass, such as a finger or hand, is placed in close proximity to it. When this occurs, the electric field around the conductor changes, allowing a measurement of the change in capacitance. The sensor uses this measurement to accurately detect the presence of an object without the use of mechanical parts.

The QT110A-ISG is almost universal in its application fields and is suitable for use in the following areas:

• Electronic switch applications, such as push buttons, power on/off buttons, channel selectors, and dimmers
• Pointing device applications, such as mouse or trackpad
• Gesture recognition applications, allowing users to activate or control a device with a simple hand gesture
• Industrial and medical applications where small size, durability and reliability are paramount
• Automotive and marine applications, as its low power operation is ideal for applications in these environments

The QT110A-ISG is designed to operate in a wide range of temperatures, from -40°C to +85°C, making it suitable for a variety of environmental conditions. It is also designed for low power operation, enabling it to be used in energy-sensitive applications.

The QT110A-ISG is a versatile, cost-effective solution for many applications that require accurate sensing of objects in close proximity. Its low power operation makes it ideal for use in a variety of environments, from automotive and marine applications to industrial and medical applications. It is suitable for use in electronic switch applications, gesture recognition applications, and pointing device applications. Its wide temperature range and low power consumption make it an ideal choice for energy-sensitive applications.
