74502 Auger Speed Sensor

This Speed Sensor from Auger (MPN: 74502) is a vital part of the ABS system, responsible for detecting vehicle speed. Its primary usage context is in brake controls, where precise speed data is critical. The technical benefits include enhanced stopping performance and reduced risk of wheel lockup. 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.
