ASB technology

ASB instrumented wheel bearings are equipped with a seal that integrates a multipolar magnetic ring which, when it rotates, can actuate a miniature active magnetoresistance or Hall effect sensor placed nearby.
The sensor, which is not integrated in the bearing but can be attached by clipping, for example, delivers a digital signal as soon as the wheel starts to rotate. This type of signal, which is not standardized, is compatible with the modern user systems (ABS, ESP, etc).
