Magnetic speed sensors

Infineon’s Hall- and GMR-based magnetic speed sensors are designed to measure speed in safety and powertrain appli-

cations such as speedometers, ABS, camshafts/crankshafts, and automatic transmissions. They are also used in similar

applications in the industrial sector. The sensors use a ferromagnetic gear tooth or encoder structure to measure linear or

rotational speed and position. Hall sensor measuring rotational speed with a gear tooth and a magnetic encoder wheel.

The majority of sensors also feature additional benefits such as integrated capacitorsfor high EMC robustness and the

highest levels of ESD protection.
