ADBP710131 Blue Print ABS Sensor

An ABS Wheel Speed Sensor is a vital part of an anti-lock braking system, responsible for detecting the rotational speed of each wheel. This information is crucial in preventing wheel lockup during hard braking, which can lead to loss of vehicle control. The sensor's accurate readings enable advanced safety features like electronic stability control and traction control systems. 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.
