It directly supports the reliable operation of anti-lock braking systems (ABS) and electronic stability control (ESC), reducing braking distance deviations by up to 15% in tests. As a professional high-precision wheel speed sensor, it avoids data lag caused by low-quality components.
Dual Global Automotive Certifications for Quality Assurance
The product is fully certified by ISO 9001 and IATF 16949—the two most authoritative standards in the automotive industry. Every unit undergoes 100% pre-delivery testing, including electrical performance, waterproofing (IP6K9K rating), and vibration resistance. Our factory’s annual product qualification rate stays above 99.7%, far exceeding industry averages, which builds long-term trust for overseas distributors.
Extreme Environment Durability with Premium Materials
Adopting reinforced ABS housing and tinned copper wires, the sensor maintains stable performance in extreme temperatures ranging from -40℃ to 150℃—adapting to both frigid northern regions and high-temperature desert areas. Its corrosion-resistant coating passed 500-hour salt spray testing, ensuring an average service life of 80,000+ km. This durability makes it a cost-effective choice for end-users.
OE-Grade Replacement for Easy Installation & Wide Adaptability
As an OE replacement wheel speed sensor, it matches the original part’s dimensions and electrical parameters perfectly, requiring no modifications during installation. Most mechanics can complete the replacement in 30 minutes or less, saving labor costs. It is compatible with 95%+ relevant vehicle platforms, reducing the need for inventory of multiple SKUs for independent station operators.
12-Month Warranty & Professional After-Sales Support
We provide a 12-month global warranty for the 3550120-K00 Wheel Speed Sensor—longer than the 12 month warranty of most competitors. Our after-sales team offers 24-hour technical support in English, including installation guides and troubleshooting videos. Over 98% of customer issues are resolved within 48 hours, enhancing customer satisfaction and repeat purchase rates.

Product Uses
Here are specific application scenarios of Wheel Speed Sensor:
Extreme Climate Driving Environments
It performs stably in temperatures from -40℃ to 150℃, adapting to frigid northern winters and high-temperature desert areas. With an IP6K9K waterproof rating, it resists rain, snow, and high-pressure car washes. Tests show 99.9% signal stability even after 72 hours of continuous exposure to harsh weather, ensuring reliable ABS/ESC operation.
Daily Urban & Highway Commuting
For frequent stop-and-go urban driving and high-speed highway travel, its ≤0.01s response time and 99.9% data accuracy enable the ECU to adjust braking force in real time. This reduces braking distance deviations by up to 15% (vs. low-quality sensors), lowering collision risks during sudden stops or lane changes.
High-Frequency Commercial Vehicle Operations
Ideal for commercial vehicles with high annual mileage (e.g., logistics vans, passenger buses), it has an 80,000+ km average service life. The 500-hour salt spray resistance (ASTM B117 standard) prevents wire/casing corrosion from road salts, cutting replacement frequency by 40% for fleet operators.
Professional Automotive Repair & Aftermarket Replacement
As an OE-grade replacement sensor, it matches original dimensions perfectly—no modifications needed. Mechanics complete installations in 30 minutes or less, saving 50% of labor time vs. non-OE parts. Backed by a 24-month warranty, it’s a trusted choice for repair shops and independent station resellers.
Automotive Performance Tuning & Modification
Its stable digital Hall effect signal (0–1000 Hz frequency range) is compatible with modified ECUs. It maintains precision even under high vibration (compliant with IEC 60068-2-6), making it suitable for performance-focused users who upgrade braking or suspension systems while needing reliable speed data.
Product Operate Guide
Follow this professional guide (aligned with IATF 16949 standards) for smooth operation: First, power off the vehicle to avoid electrical risks. Use a standard socket wrench to remove the old sensor, then align the 3550120-K00 with the original mounting hole and fasten it (torque: 8-10 N·m). Finally, power on and test—ensure no ABS warning light appears (signal stability ≥99.9% indicates success). Total installation takes ~30 mins for skilled mechanics.
