Vemo V42-72-0001 Brake

Vemo V42-72-0001 Brake Sensor Overview

The Vemo V42-72-0001 is a high‑performance wheel speed sensor designed for use in anti‑lock braking systems (ABS). It delivers precise rotational data to the vehicle’s electronic control unit, ensuring optimal brake modulation and stability during emergency stops.

Key Functional Characteristics

• Sensor Type: Hall effect magnetic sensor with integrated signal conditioning.
• Signal Output: Low‑impedance square wave suitable for direct connection to ABS modules.
• Operating Temperature Range: –40 °C to +120 °C, guaranteeing reliable performance in extreme climates.
• Power Supply: 12 V DC nominal; operates within a tolerance of ±10 %.
• Signal Frequency: Up to 20 kHz, allowing accurate wheel speed measurement at high velocities.

Mechanical and Electrical Design

The sensor features a compact cylindrical housing that fits standard wheel hub mounting points. Its robust construction protects against vibration, shock, and moisture ingress (IP67 rating). The integrated magnetic core provides stable operation even when the vehicle experiences rapid acceleration or deceleration.

Mounting Interface

• Thread Size: M6 x 1.0 mm.
• Mounting Plate: Stainless steel, corrosion‑resistant finish.
• Connector Type: 3‑pin JST or equivalent automotive connector for secure electrical coupling.

Electrical Pinout

Compatibility and Vehicle Applications

The V42-72-0001 is engineered to replace original equipment sensors in a wide range of vehicles, particularly those equipped with the Vemo ABS system. Common applications include:

• Peugeot Models: 206 (3/5‑door hatchback), 206 SW, and 206 Van.
• Front axle wheel speed sensors for both left and right wheels.
• Vehicles requiring a wheel speed sensor that meets OEM specifications.

Installation Guidelines

1. Safety First: Disconnect the vehicle’s battery to prevent accidental electrical discharge.
2. Remove Old Sensor: Unscrew the existing sensor from the wheel hub and disconnect its wiring harness.
3. Align New Sensor: Position the V42-72-0001 so that the magnetic core aligns with the wheel’s rotating shaft.
4. Screw Securely: Tighten to the manufacturer’s torque specification (typically 10 Nm).
5. Reconnect Wiring: Attach the connector, ensuring a firm click‑lock engagement.
6. Reboot System: Reconnect the battery and allow the ABS module to recalibrate automatically.

Performance Benefits

• Enhanced Accuracy: Hall effect technology reduces signal noise, providing cleaner wheel speed data.
• Reliability: IP67 protection and robust housing extend sensor life in harsh operating environments.
• Low Power Consumption: Efficient design minimizes drain on the vehicle’s electrical system.
• Seamless Integration: Direct compatibility with existing ABS modules eliminates the need for additional adapters or calibration tools.

Technical Data Sheet Summary

Maintenance and Troubleshooting Tips

• Inspect the sensor housing for cracks or corrosion before installation.
• Verify that the magnetic core is free of debris; clean with a soft brush if necessary.
• If ABS warning lights illuminate, check wiring continuity between the sensor and the control module.
• Use a diagnostic scan tool to confirm proper wheel speed readings after installation.

Conclusion

The Vemo V42-72-0001 Brake Sensor delivers reliable, high‑precision wheel speed data essential for effective ABS operation. Its robust design, straightforward installation process, and proven compatibility with a broad range of vehicles make it an ideal choice for automotive technicians and enthusiasts seeking to maintain or upgrade their vehicle’s braking safety systems.
