When the pulse wheel rotates, the sensor generates an alternating current signal that the ABS control module uses to modulate braking force, preventing wheel lock-up during hard braking and supporting Anti-Slip Regulation (ASR) systems. The sensor mounts directly above the pulse/tone wheel at the wheel hub or drive shaft. Hella's commercial ABS sensor program is backed by over 120 years of OEM manufacturing expertise, making it a trusted choice for fleet maintenance and repair.
