Technical Specifications

Design and Build Quality

The Vemo V32-72-0050 features a rugged steel housing that protects the internal Hall‑Effect sensor from mechanical shock, moisture, and dust. The epoxy insulation ensures electrical isolation while maintaining low thermal resistance. Its compact form factor allows it to be mounted directly onto the wheel hub or brake assembly without requiring additional space.

Functionality in ABS Systems

In an Anti‑Lock Braking System, each wheel’s rotational speed is continuously monitored by sensors like the V32-72-0050. The sensor generates a pulse train proportional to wheel velocity. This data feeds into the vehicle’s Electronic Control Unit (ECU), which calculates braking force distribution and prevents wheel lockup during emergency stops.

Compatibility Overview

The Vemo V32-72-0050 is engineered for broad compatibility:

• Front‑Wheel Applications: Suitable for front‑wheel drive vehicles and all‑wheel drive configurations.
• Rear‑Wheel Applications: Can be installed on rear wheels of rear‑wheel drive models.
• Vehicle Brands: Tested on Ford, Mazda, and other OEMs that require precise wheel speed data.

Installation Guide

1. Preparation: Disconnect the vehicle battery to ensure safety. Remove the existing sensor or wheel hub as needed.
2. Alignment: Position the V32-72-0050 so that its magnetic field aligns with the wheel’s rotating magnet or toothed rim.
3. Bolt Securely: Use the supplied mounting bolts and torque specifications to secure the sensor. Ensure alignment pins are correctly seated.
4. Cable Routing: Route the sensor cable along the vehicle’s designated path, avoiding sharp bends and securing it with zip ties.
5. Connection: Connect the sensor output to the ECU or ABS module following the manufacturer’s wiring diagram. Verify polarity and signal integrity.
6. Testing: Reconnect the battery and perform a diagnostic scan to confirm sensor operation. Check for proper pulse frequency corresponding to wheel speed.

Maintenance Tips

• Inspect the sensor housing for cracks or corrosion every 20,000 miles.
• Clean the magnetic field area with a soft brush to remove debris that may interfere with signal generation.
• Verify cable insulation integrity; replace any frayed sections immediately.
• Use only OEM-approved replacement parts to maintain performance standards.
