Description
Restore precise wheel speed signal monitoring and prevent wheel lockup under heavy braking with the genuine WABCO Commercial Vehicle ABS Wheel Speed Sensor. Engineered specifically for heavy-duty commercial trucks, luxury passenger buses, and multi-axle freight trailers, this OE-grade inductive speed sensor feeds real-time rotational frequency directly to the ABS/EBS electronic control unit. Damaged, corroded, or short-circuiting sensors trigger immediate ABS warning faults, disable anti-lock braking intervention, and extend stopping distances on wet or slippery road surfaces. This original WABCO sensor solves those critical safety failures directly. It features high-sensitivity electromagnetic pickup coils, IP69K sealed waterproof connectors, and rugged high-temperature shielding cables to deliver clear pulse signals and maintain active vehicle stability in demanding transport operations.
Technical Parameters
| Category | Specifications & Technical Details |
| High-Sensitivity Inductive Signal Pickup | We wind a specialty electromagnetic coil from high-purity enameled wire. As a result, it captures the tone ring rotational square-wave signal with millisecond-level precision. Moreover, it maintains clear and stable electrical pulse output even at extremely low vehicle speeds. |
| IP69K Sealed Waterproof & Corrosion Protection | We injection-mold the sensor body in one piece from high-temperature engineering plastic. Consequently, it achieves the IP69K extreme dust and waterproof rating, completely sealing out chassis-splashed mud, de-icing salt chemical attack, and brake high-temperature baking. |
| High-Temperature & Abrasion-Shielded Harness Cable | We wrap the cable outer layer with oil-resistant, anti-aging specialty fluororubber and polyurethane (PUR) jacketing. As a result, it withstands brake disc radiant heat up to +150°C and mechanical interference wear. |
| OEM-Grade EMC Electromagnetic Interference Shielding | We build in a multi-layer metal shielding mesh. Consequently, it effectively blocks strong electromagnetic interference generated by heavy truck high-voltage ignition, electric motors, and on-board radio equipment. Notably, this guarantees distortion-free, noise-free signal transmission to the ABS ECU. |
| Precision Friction Sleeve & Clip Mounting Geometry | We design the sensor to comply with ISO 611 international braking standards. Additionally, we pair it with an elastic clamping sleeve for push-in quick locking and positioning. Therefore, it maintains the optimal air gap tolerance between the sensor head and the tone ring. |
Applicable Car Brands & Models
Common warning symptoms include:
ABS / Yellow Brake Warning Light Illuminated: The dashboard displays an active ABS fault code indicating sensor open-circuit, short-circuit, or signal loss.
Premature ABS Activation or Erratic Braking: The ABS system pulses unexpectedly under light braking due to inconsistent wheel speed readings.
EBS and Traction Control Disabled: Advanced stability programs (EBS/ESC) automatically shut down when the ECU loses speed input from a single wheel.
Visible Cable Damage or Debris Accumulation: Broken wiring, melted cable jackets, or heavy metallic dust build-up on the sensor tip.
We source all WABCO safety components directly through official authorized OEM distribution channels. Each sensor features original WABCO factory packaging, engraved OEM part numbers, and batch tracking codes, ensuring authentic quality and reliable availability for global B2B buyers.
Our 1-year warranty covers all internal coil short-circuits, factory manufacturing defects, and non-artificial signal dropouts under normal vehicle operating conditions. If a sensor fails within 12 months, we provide prompt replacement or warranty processing upon inspection.
Yes. Replacing the copper clamping sleeve (friction spring clip) alongside the new sensor is highly recommended. A fresh clamping sleeve ensures proper holding force, retains the correct air-gap distance to the tone ring, and prevents the sensor from sliding loose due to wheel vibration.
