Infineon Technologies XENSIV™ Hall-, GMR- and TMR-based magnetic speed sensors are designed specifically for measuring speed in safety and powertrain applications, such as speedometers, ABS, camshafts/crankshafts, and automatic transmissions. These sensors are also applied in similar industrial applications. The speed sensors utilize a ferromagnetic gear tooth or encoder structure to measure linear or rotational speed and position. A Hall-based sensor, for instance, measures rotational speed using a gear tooth and a magnetic encoder wheel. Additionally, the majority of these sensors offer several enhanced features, such as integrated capacitors for superior EMC robustness and top-tier ESD protection.
