Wheel Speed Sensors

Our patented, best-in-class GMR technology provides low jitter and high air gap over the widest installation tolerance—it also offers high accuracy for extremely precise wheel speed and position measurement, ideal for advanced braking and autonomous vehicle applications. Allegro's advanced, dynamic algorithms compensate for anomalies in driving behavior, guaranteeing steady state output behavior in the presence of system variation. 

Plus, safety is one of our top priorities. Allegro offers a full line of Hall-based wheel speed devices designed to ISO 26262 specifications (pending assessment) for applications with both ferrous and ring magnet targets.
