ADC47121 Blue Print ABS Sensor

The ABS Sensor (ADC47121 by Blue Print) plays a critical role in maintaining vehicle stability during braking maneuvers. Primarily used in brake controls of passenger cars and light trucks, this sensor accurately monitors wheel speed and prevents wheel lockup. Its compact dimensions of 178.0 x 51.0 x 142.0 mm make it suitable for various applications. Dimensions are provided by the supplier and may include packaging dimensions. 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.
