Hella 230040061 ABS Wheel Speed Sensor

The Hella 230040061 is an ABS wheel speed sensor (WSS) engineered to OEM standards for commercial vehicle anti-lock braking systems. As an inductive, passive sensor, it continuously monitors wheel rotational speed and delivers precise alternating-current signals to the vehicle's ABS control unit — enabling the system to prevent wheel lock-up during braking and support traction control functions.

Key Features:

• OEM-Grade Construction: Built to original equipment specifications for direct, 1-to-1 replacement without modification
• Inductive Passive Design: Operates without external power supply; generates its own signal via electromagnetic induction from the rotating tone ring
• Durable Cable Assembly: Includes a dedicated wiring harness and connector socket engineered for secure, weather-resistant fitment
• High-Temperature Tolerance: Designed to perform reliably in the harsh thermal and vibration environment near the wheel hub and brake assembly
• Precise Signal Output: Delivers accurate speed data to the ABS/ASR (Anti-Slip Regulation) module for optimal braking intervention
• Easy Installation: Mounts directly above the pulse/tone wheel on the hub or drive shaft as a plug-and-play replacement
