Anti-lock Braking System (ABS) and Vehicle Stability Control (VSC)

Our high accuracy GMR technology provides extremely precise wheel speed and position measurement to the ABS controller—critical to your anti-lock braking systems. Our patented, best-in-class Allegro GMR technology also provides low jitter and high air gap over the widest installation tolerance, and advanced dynamic algorithms that compensate for anomalies in driving behavior, guaranteeing steady state output behavior in the presence of system variation. 

Don't forget—Allegro also provides a culture of safety and quality control. We offer a full line of Hall-based devices designed to ISO 26262 specifications for safety critical appliations like anti-lock braking.
