Technical Specifications

Applications

The Vemo V52-72-0078 is engineered for use in a variety of vehicle platforms, including:

• Front and rear wheel speed monitoring for ABS (Anti‑Lock Braking System)
• Input to ESP (Electronic Stability Program) modules
• Traction control systems in passenger cars, SUVs, and light commercial vehicles
• Hybrid and electric vehicle wheel speed sensing for regenerative braking management
• High‑performance racing applications where precise wheel data is critical

Installation Guidelines

1. Remove the existing sensor by disconnecting the wiring harness and unscrewing the mounting bolts.
2. Align the new sensor with the wheel hub’s magnetic rotor, ensuring the Hall element faces the rotating magnet.
3. Screw the sensor into place using the supplied mounting hardware; torque specifications are typically 5 Nm.
4. Reconnect the wiring harness, verifying correct polarity and secure connections.
5. Test the signal output with a diagnostic scan tool to confirm proper operation before closing the wheel well.

Maintenance & Troubleshooting

• Inspect for physical damage or corrosion on the sensor housing and connector pins during routine service checks.
• Verify that the wheel hub rotor is clean; debris can interfere with magnetic coupling.
• If the signal amplitude drops below specifications, check for electrical noise or grounding issues.
• Replace the sensor if it exhibits intermittent output or fails diagnostic tests.
