Product Uses
Here are specific application scenarios of Wheel Speed Sensor:
1. Daily Urban Commuting
Ideal for stop-and-go urban traffic, this sensor maintains stable ±0.1% speed detection accuracy even during frequent acceleration/deceleration. Its ≤10ms response time ensures the ABS system acts quickly to prevent wheel lock-up at intersections or in congested areas. Compliant with ISO/TS16949, it resists signal interference from city electromagnetic environments (e.g., traffic lights), keeping safety systems functional.
2. Long-Distance Highway Cruising
For high-speed highway travel (0–250 km/h), the sensor’s 0–5 kHz output frequency range matches real-time speed changes precisely. It withstands continuous 125℃ under-hood temperatures (per IEC 60068-2-2) during long drives, avoiding performance drops. Its low signal lag (20% less than generic sensors) supports ESC systems, enhancing stability during lane changes or sudden speed adjustments.
3. Severe Weather & Complex Road Conditions
In rain, snow, or muddy terrain, its IP6K9K protection grade blocks water/dust intrusion—critical for preventing sensor short circuits. It passes 5,000-hour salt spray tests (ASTM B117), resisting corrosion from road salt in winter. On slippery roads, its consistent signal ensures the ABS modulates brake pressure accurately, reducing skid risks by 30% (vs. faulty sensors).
4. Commercial & High-Frequency Usage
For vehicles with heavy daily use (e.g., delivery vans, taxis), the sensor’s 50,000+ hour durability rating (double the industry average) minimizes replacement frequency. Its vibration resistance (10–2000 Hz, ISO 16750-3) handles constant road shocks, while the 24-month warranty provides long-term reliability for fleet operators.
Product Operate Guide
Prep Safely: First, disconnect the vehicle’s battery (per automotive safety standards) to avoid electrical shorts. Confirm the old sensor’s connector type matches the M11-3550111 (AMP 1-967609-1) for a proper fit.
Install Gently: Remove the old sensor, then align the new one with the mounting hole—apply light force (avoid over-tightening) to prevent housing damage. Plug in the connector until you hear a “click” (ensures low contact resistance <50 mΩ).
Test & Verify: Reconnect the battery, start the vehicle, and check that the ABS light turns off. For confirmation, use a diagnostic tool to verify the sensor’s output frequency (0–5 kHz is normal). Contact our tech team if issues arise.
