Wheel Speed Sensor ICs

Wheel Speed Sensor ICs

wheel sensor, abs wheel speed sensor

Allegro offers a selection of wheel speed sensors optimized for today¡¯s demanding ABS applications.  Solutions are available for either ferrous targets or magnetic encoder rings, and for speed or speed-and-direction sensing capability. Allegro¡¯s wheel speed sensors provide optimized performance in the presence of harsh automotive conditions.  Advanced peak-detection algorithms provide robustness against vehicle dynamics, such as hard cornering, and micro-oscillations in static modes. 

Allegro¡¯s solutions offer over a decade of ABS specific IC designs based on the industry¡¯s top professionals and vehicle manufacturers' expertise. These sensor ICs also incorporate over a decade of lessons learned through the harsh, automotive scrutiny of in-vehicle testing and production. Allegro¡¯s wheel speed sensors are offered in two current range options each using a two-wire, current output protocol. Direction information is offered in a two-wire, pulse width output protocol.
