Infineon Technologies XENSIV™ 3D Magnetic Sensors

Infineon XENSIV 3D Magnetic sensors offer accurate three-dimensional sensing with extremely low power consumption in a small 6-pin package. With its magnetic field detection in x, y, and z-direction, the sensor reliably measures three-dimensional, linear and rotation movements. Applications span from joysticks, control elements, and multifunction knops for smart home applications to white goods. Another field of application is electric meters (anti-tampering). The XENSIV 3D Magnetic Sensors are utilized in all types of robots, industrial and service ones as well as in drones. Automotive environment applications such as indicators and gear shifters rely on Infineon’s 3D sensors. Other applications that require accurate angular measurements or low-power consumption are ideal for using magnetic sensors. The XENSIV 3D Magnetic Sensors are designed for all kinds of sensing applications including out-of-shaft angle measurement and position detection.
