An ABS Sensor is a vital part of a vehicle's brake system, detecting wheel speed and transmitting data to the control unit to prevent wheel lockup during hard braking. It is commonly used in passenger cars and light trucks. This sensor offers improved stability and control, reducing wear on brake components and enhancing overall safety.
ABS sensors are electromagnetic devices that monitor wheel rotational speed and report this data to the vehicle’s ABS control module. Typically mounted near each wheel hub and brake rotor, they utilize a toothed reluctor ring or magnetic encoder to generate an AC voltage signal proportional to wheel speed. Sensor output is critical for ABS, traction control, and electronic stability control system functionality, enabling precise determination of wheel slip and imminent lockup. These sensors are commonly inductive, Hall-effect, or magnetoresistive, each offering varying sensitivity and temperature range characteristics. Signal integrity is maintained through shielded wiring and robust mounting to minimize interference and ensure accurate readings.
