Description
Restore real-time wheel speed tracking and ensure optimal anti-lock braking performance on your commercial fleet with the genuine WABCO Commercial Vehicle ABS Wheel Speed Sensor. Engineered specifically for heavy-duty commercial trucks, multi-axle freight haulers, and transit coaches, this OE-grade inductive sensor monitors accurate wheel rotation and transmits high-frequency signals directly to the ABS/EBS control unit. Corroded sensor tips, cracked wiring harnesses, excessive air gap spacing, or internal coil breaks cause permanent ABS warning lights, disabled traction control, and unpredictable wheel lockups during emergency stops. This original WABCO sensor solves those signal failures directly. It features a rugged magnetic core, a sealed waterproof housing, and a vibration-resistant connector to deliver precise frequency generation, flawless ECU communication, and uncompromised stopping safety in demanding transport operations.
Technical Parameters
| Category | Specifications & Technical Details |
| High-Precision Inductive Signal Generation | We use a high-purity copper induction coil and permanent magnet core. As the wheel tone ring spins at speed, it cuts magnetic field lines and generates a high-precision sine wave pulse signal. As a result, the ABS computer calculates vehicle speed and slip ratio accurately. |
| IP67/IP69K Waterproof & Dustproof Shielding | We laser-weld the sensor probe and harness connector and encapsulate them with high-density epoxy resin. Consequently, it achieves the IP67 / IP69K extreme waterproof and dustproof rating. Moreover, it fully resists high-pressure water jet washing, mud immersion, and road de-icing salt corrosion. |
| High-Temperature Armored Wiring Harness | We insulate the conductors with oil-resistant, wear-resistant fluororubber and specialty silicone jackets. Additionally, we wrap the outer layer with a corrugated tube or metal armored mesh. Therefore, it withstands extreme temperature differentials from -40°C to 150°C and high-frequency suspension torsion tugging. |
| Optimized Air-Gap Tolerance Geometry | We design the probe end face with a standard geometric chamfer. It maintains a precise micron-level installation air gap with the tone ring. As a result, this prevents signal loss or probe wear caused by slight axle bounce. |
| OEM-Grade Electromagnetic Compatibility Shielding | We build in anti-interference twisted pair wires and a shielding copper mesh. They effectively isolate electromagnetic noise from heavy truck high-power alternators, high-voltage ignition, and radio transmissions. Notably, this guarantees zero packet loss and noise-free signal transmission. |
Applicable Car Brands & Models
Common warning symptoms include:
Permanent ABS Warning Light on Dashboard: The instrument cluster displays an active ABS or traction control fault code linked to a specific wheel position.
Premature ABS Activation: The anti-lock braking system triggers inappropriately at low speeds on dry pavement because the sensor sends erratic or weak signals.
Diagnostic Code for Open Circuit: Diagnostic scanners read open circuit, short to ground, or erratic frequency errors from the sensor node.
Physical Damage on Sensor Tip: Visible scraping, cracking, or thermal damage on the sensor probe caused by excessive wheel bearing play or debris buildup.
Premature sensor failure is typically caused by worn wheel hub bearings that allow excessive axial play, causing the tone ring to strike the sensor tip. Other causes include wiring harness fatigue from continuous suspension articulation, or moisture penetration through cracked insulation.
No software programming is required to replace an inductive ABS wheel speed sensor. Once the new sensor is installed with the correct air gap and the wiring harness is securely connected, simply clear the historical fault codes using a diagnostic tool and test-drive the vehicle to extinguish the dashboard warning light.
Our 1-year warranty covers all internal coil burnouts, electrical resistance defects, signal output failures, waterproof sealing flaws, and non-artificial component failures under normal operating conditions. If a sensor fails within 12 months, we provide prompt replacement or warranty processing upon inspection.
