Touch Sensors

Touch sensors are highly reliable and convenient devices that do not have any moving parts. They are designed to detect touch and provide a responsive output signal. There are two main types of touch sensors: infrared and resistive. Infrared touch sensors use IR beams to detect when there is a touch. When an object touches the surface of the sensor, it blocks the IR beam, causing a change in the output signal. These sensors are commonly used in various electronic devices such as smartphones, tablets, and digital kiosks. Resistive touch sensors, on the other hand, exhibit a decrease in resistance when force is applied to the surface of the sensor. The change in resistance is detected by the sensor's controller, which translates it into a touch input. Resistive touch sensors are ideal for applications that require a high level of accuracy and precision, such as industrial automation and medical equipment. Furthermore, touch sensors offer various output types to suit different application requirements. These include analog, I2C, and USB. The termination style of touch sensors can also vary and includes card edge/solder pad, connector, flex cable, solder tab, and tab. With their reliability and convenience, touch sensors are becoming increasingly popular in various industries. They provide a seamless user experience and simplify device operation. Overall, touch sensors are versatile and customizable devices that offer responsive touch detection and a range of output options to meet diverse application needs.
