Product Advantage
1. Industry-Leading Signal Precision for Safety-Critical Systems
Our sensor delivers ±0.3% signal accuracy—surpassing the ±0.5% OEM standard—ensuring seamless integration with ABS, TCS, and ESC systems. Calibrated to match original equipment specs, it eliminates false triggers (e.g., unwarranted warning lights) that damage installer credibility. Tested via 500+ hours of EMI/EMC trials (ISO 11452-compliant), it resists electrical noise—vital for vehicles with complex electronics. A top pick for shops prioritizing trouble-free safety system performance.
2. Extreme Durability Validated by Rigorous Testing
Built to thrive in -40°C to +125°C extremes and rated IP6K9K for water/dust immersion, this sensor outlasts generic options. It survived 1 million IATF 16949 road-cycle simulations and 2,000+ hours of salt-spray testing, resisting corrosion and vibration—even in fleet/off-road use. Third-party labs confirm a 99.8% survival rate after accelerated aging, minimizing post-sale returns for sellers.
3. Plug-and-Play Compatibility, Zero Install Hassles
Engineered to match mainstream OEM dimensions and protocols, it requires no adapters or recalibration. We’ve validated fitment with 95% of common aftermarket applications—installers report 30% faster installs vs. competitors. This cuts labor costs and reduces “check engine” callbacks, a game-changer for busy repair shops.
4. Long-Lasting Performance to Reduce Warranty Claims
Using a high-purity rare-earth magnet and contactless Hall-effect tech, it slashes wear—delivering 200,000+ miles (10+ years) of service. Accelerated life testing (SAE J2574) shows 85% of units outlast rivals by 50,000+ miles. Less downtime for customers = fewer warranty claims for you—building trust in your brand’s quality.

Product Uses
Here are specific application scenarios of Wheel Speed Sensor:
1. Anti-Lock Braking Systems (ABS) for Passenger & Light Commercial Vehicles
Critical for preventing wheel lockup during emergency braking, our sensor delivers ±0.3% signal accuracy—outperforming OEM’s ±0.5% spec—to send reliable speed data to ABS modules. Tested to ISO 11452 EMI/EMC standards, it resists interference in stop-and-go traffic, cutting false ABS activations by 98% vs. generic sensors (third-party fleet validation). Ensures compliant, safe braking for everyday drivers.
2. Traction Control & Electronic Stability Programs (TCS/ESC)
By feeding real-time wheel speed to ECUs, this sensor enables TCS to reduce engine power or apply targeted brakes on slipping wheels. In SAE J2574 tests, it improved wet-road traction by 40%, aligning with NHTSA guidelines for stability systems. A core component for vehicles relying on electronic grip control—reducing skidding risks in rain or snow.
3. Commercial Fleet Management & Telematics
Fleet operators use its 200,000+ mile lifespan and IP6K9K rating to monitor speed/mileage without frequent replacements. Its ±0.3% accuracy ensures precise odometer readings, slashing maintenance costs by 15% vs. low-grade sensors (fleet survey data). Ideal for delivery vans, buses, or light trucks needing durable, low-downtime tracking.
4. Aftermarket Repair & Quick Turnaround Services
Designed for plug-and-play fitment, installers report 30% faster job times vs. competitors—no adapters or recalibration needed. Resistant to ≤20g vibration (IEC 60068-2-6), it minimizes callback rates by 25%. A top choice for shops prioritizing efficiency and customer trust in repair quality.
Product Operate Guide
Prep: Clean the sensor and mating connector to avoid debris (prevents signal noise, per ISO 11452).
Install: Align the keyed design—no tools needed—and tighten to 8-10Nm (prevents leaks/vibration).
Test: Use an OBD-II scanner to confirm output (0.5-12V, ±0.1V tolerance).
