79271 Auger Speed Sensor

A Speed Sensor from Auger (MPN: 79271), made in China, plays a vital role in modern vehicles by accurately monitoring speed. Installed within the ABS system, it ensures safe and controlled braking performance. Key advantages of this component include enhanced precision in speed detection and quicker reaction times during critical braking events. 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.
