Vemo V30-72-0168 Sensor, wheel speed

Vemo V30-72-0168 – Precision Wheel Speed Sensor for Mercedes‑Benz Vehicles

The Vemo V30-72-0168 is a high‑performance wheel speed sensor designed to deliver accurate rotational data to the vehicle’s Anti‑Lock Braking System (ABS). Engineered with automotive‑grade materials and precision manufacturing, this sensor ensures reliable operation under the demanding conditions of modern driving.

Key Functionalities

• Accurate Wheel Speed Detection: Captures real‑time rotational speed of the rear right wheel with minimal latency.
• ABS Integration: Provides critical input to the ABS control unit, enabling optimal brake modulation during emergency stops.
• High Signal Integrity: Features a robust magnetic sensor core that resists electrical noise and maintains signal clarity.
• Durable Construction: Encased in a corrosion‑resistant housing to withstand road salts, moisture, and temperature extremes.

Design & Engineering Highlights

The sensor’s architecture incorporates a permanent magnet and a Hall‑effect element. As the wheel turns, the magnetic field induces a voltage proportional to rotational speed. This analog signal is then converted into a digital pulse train that the ABS module interprets.

• Magnetic Core: High‑purity neodymium alloy for stable magnetic flux.
• Hall Sensor: Low‑drift, temperature‑compensated semiconductor element.
• Signal Output: Standard 12 V DC supply with a 5 kΩ pull‑up resistor to match vehicle specifications.
• Mounting Interface: Flange design aligns with the OEM wheel hub, ensuring secure attachment and minimal vibration.

Compatibility Overview

The Vemo V30-72-0168 is specifically calibrated for the rear right wheel of the Mercedes‑Benz C‑Class lineup. It matches the original sensor’s electrical characteristics, ensuring seamless integration without the need for additional adapters or modifications.

Installation Guide

1. Safety First: Disconnect the vehicle’s battery to prevent accidental electrical discharge.
2. Remove Old Sensor: Use a socket set to detach the wheel hub assembly. Carefully extract the existing sensor, noting its orientation.
3. Prepare New Sensor: Align the Vemo V30-72-0168 with the mounting flange. Ensure that the magnetic pole faces the correct direction relative to the wheel’s rotation.
4. Secure Attachment: Tighten the sensor bolts to the manufacturer’s torque specifications (typically 15–20 Nm).
5. Reconnect Power: Re‑attach the battery and verify that the ABS warning light behaves normally during a diagnostic check.

Performance Benefits

• Enhanced Braking Safety: Precise wheel speed data allows the ABS to modulate brake pressure more effectively, reducing stopping distances on slippery surfaces.
• Reduced Wear: Accurate sensor readings prevent unnecessary ABS activation cycles, extending component life.
• Consistent Reliability: The sensor’s robust design minimizes false positives that could trigger unintended braking interventions.

Troubleshooting Common Issues

Maintenance Tips

• Inspect the sensor housing for cracks or corrosion every 20,000 km.
• Clean the sensor surface gently with a soft brush to remove debris that may impede magnetic coupling.
• Avoid using abrasive cleaners that could damage the sensor’s protective coating.
