Febi ABS Ring (171389)

The gear-like shaped ABS ring (also rotor or sensor ring) acts as a counterpiece to the ABS speed sensor for recording the speed or the speed change of the wheel on which it is installed. The constant alternation of tooth and tooth space during wheel rotation causes a change to the magnetic field in the ABS sensor, resulting in the induction of sinusoidal AC voltages. Their frequency depends on the wheel speed and is evaluated by the ABS control unit.

The ABS ring is made of high-quality steel and is coated with a surface protector. Febi bilstein offers a large number of braking spare parts, including ABS rings, which are tested intensively for various requirements and loads by their certified quality management.
