Installation Guidelines

Proper installation is critical for optimal sensor performance. Follow these steps to ensure accurate wheel speed measurement:

1. Locate the Wheel Hub: Identify the mounting flange or threaded hole on the vehicle’s front or rear hub.
2. Align the Sensor: Position the sensor so that its magnetic field aligns with the rotating wheel rim. The Hall‑effect element must be centered over the wheel’s rotation axis.
3. Screw Securely: Tighten the mounting screws to the manufacturer’s torque specifications (typically 10–15 Nm). Avoid overtightening, which can damage the sensor housing.
4. Wire Connections: Connect the sensor leads to the vehicle’s ABS or traction control module. Ensure polarity is correct: positive (+) to the supply line and negative (−) to ground.
5. Check Signal Integrity: Use a diagnostic scan tool to verify that the sensor outputs a clean square wave at expected frequencies during wheel rotation.

Performance Features

• High Accuracy: The Hall‑effect principle provides precise detection of magnetic field changes, translating directly into accurate wheel speed data.
• Low Power Consumption: Designed to operate efficiently within the vehicle’s electrical system, minimizing battery drain.
• Durability: Rugged housing resists vibration, shock, and environmental contaminants such as dust and moisture.
• Fast Response Time: Rapid signal generation ensures real‑time feedback for ABS and stability control systems.
• Compact Design: Small footprint reduces installation complexity in tight engine bay spaces.

Maintenance Tips

While the sensor is built for long‑term reliability, routine checks can extend its lifespan:

• Inspect mounting bolts every 10,000 km to ensure they remain secure.
• Clean the sensor housing and surrounding area with a soft brush to remove debris that could interfere with magnetic coupling.
• Verify electrical connections for corrosion or loose contacts during regular maintenance intervals.
