TE Connectivity Anisotropic Magneto-Resistive (AMR) Sensors
TE Connectivity Anisotropic Magneto-Resistive (AMR) Sensors are engineered to deliver precise, reliable magnetic field detection across a wide range of industrial and automotive applications. Utilizing advanced AMR technology, these sensors provide high sensitivity, excellent linearity, and superior performance even in harsh environments. The sensors are designed for contactless position and speed sensing, reducing mechanical wear and enhancing system longevity. With low power consumption and a robust design, TE Connectivity AMR sensors operate efficiently across extreme temperatures and challenging conditions, making them ideal for applications that demand durability and accuracy.
These sensors are commonly used for rotary and linear position sensing, speed and direction detection, gear tooth sensing, motor control feedback, and in automotive systems, such as transmissions and steering. The product lineup includes the G-MRCO prefix devices, which offer compact designs for precise magnetic field detection in demanding environments. Additionally, the KMXP series delivers high-performance sensing with enhanced sensitivity and extended operating ranges, making it ideal for advanced position and speed sensing applications.
