the ABS sensor is used in the automobile anti-lock braking system. When working, it senses the change of voltage or current, and transmits this change (signal) to the ABS computer central processing unit to determine whether the car wheels are in a sliding or rolling state, and determine the ABS system. The action parts take corresponding actions to prevent the car from slipping.

Prevents the vehicle from being clamped by the brake to cause the tire to not move relative to the brake, thereby preventing the vehicle from slipping on the road and avoiding accidents. (Abbreviation: Anti-lock Braking)
the ABS sensor is used in the ABS (Anti-lock Braking System) of the motor vehicle. In the ABS system, most of the inductive sensors are used to monitor the vehicle speed. A sinusoidal alternating current signal whose frequency and amplitude are related to wheel
Speed. the output signal is sent to the ABS electronic control unit (ECU) to realize real-time monitoring of wheel speed.
