How Active Wheel Speed Sensors Work
Active wheel speed sensors; how they work and how they differ from passive wheel speed sensors An active wheel speed sensor detects the presence of a magnetic field and reports that presence as a square wave DC digital on/off signal, as opposed to a passive wheel speed sensor which produces an analog AC signal. When used in an anti-lock brake system, an active sensor detects the alternating the north/south poles of a rotating multipole magnetic ring, usually inserted into the wheel bearing. As the wheel rotates, the active wheel speed … Read More
Understanding wheel speed sensors: How they work
Everything You Need to Know About Wheel Speed Sensors Wheel speed sensors are integral to various safety and performance systems, including Anti-lock Braking Systems (ABS), Electronic Stability Control (ESC), and Traction Control Systems (TCS). Understanding what wheel speed sensors are, the types available, and how they function provides insight into how modern vehicles maintain control and prevent accidents in various driving conditions. What wheel speed sensors do Wheel speed sensors track the rotation speed of each wheel (in most vehicles *) and report the speed in either analog or digital … Read More
