This inductive sensor delivers reliable data to the vehicle’s ABS (Anti‑Lock Braking System) and traction control modules, ensuring optimal braking performance and stability under all driving conditions.

Key Technical Specifications

• Model Number: 0900064
• Type: Inductive wheel speed sensor (Hall‑effect)
• Operating Voltage: 12 V DC
• Signal Output: Pulse frequency proportional to wheel rotation speed
• Mounting Position: Front left wheel hub
• Compatibility: Designed for vehicles with front‑wheel ABS systems, including Audi A4/A6, Seat Leon, Skoda Octavia, Volkswagen Golf/Passat/Polo/Lupo, and many others.
• Dimensions: Compact design to fit standard wheel hub assemblies
• Operating Temperature Range: -40 °C to +85 °C (typical automotive range)
• Signal Frequency: Up to 10 kHz, allowing precise speed measurement even at high vehicle speeds.

Functional Overview

The sensor operates by generating a magnetic field that interacts with the rotating wheel rim. As metallic teeth or slots on the wheel pass through this field, they induce voltage pulses in the sensor’s coil. The frequency of these pulses is directly proportional to the wheel’s rotational speed. This data is transmitted to the vehicle’s electronic control unit (ECU), which uses it to modulate brake pressure and prevent wheel lock‑up during hard braking.

Installation Highlights

• Standard Mounting: The sensor comes pre‑assembled with a mounting bracket that aligns perfectly with the front left wheel hub. No additional hardware is required for most vehicles.
• Wiring: A dedicated wiring harness connects the sensor to the ABS module. The harness includes shielded cables to minimize electromagnetic interference.
• Alignment: Proper alignment ensures accurate pulse generation. During installation, verify that the sensor’s magnetic field aligns with the wheel rim slots or teeth.
• Torque Specifications: Fasten the mounting bolts to the manufacturer’s recommended torque values (typically 30–40 Nm) to secure the sensor without over‑tightening.

Performance Benefits

• Enhanced Braking Safety: By providing real‑time wheel speed data, the sensor enables the ABS system to apply optimal brake pressure, reducing stopping distances and preventing skidding.
• Improved Traction Control: The sensor’s accurate readings allow traction control modules to detect loss of grip early and intervene with engine torque reduction or selective braking.
• Durability: Constructed from high‑grade materials, the sensor withstands harsh automotive environments, including temperature extremes, vibration, and exposure to road salts.
• Low Power Consumption: Designed for efficient operation, it draws minimal current, preserving battery life in modern vehicles with numerous electronic systems.

Compatibility Matrix

The Metzger 0900064 Sensor is engineered to fit a broad spectrum of front‑wheel ABS-equipped models. Below is an overview of typical vehicle families and model years where this sensor is a direct replacement or upgrade:

Maintenance and Troubleshooting

• Regular Inspection: Check the sensor’s wiring for signs of wear or corrosion. Inspect the mounting bolts for tightness.
• Signal Verification: Use a diagnostic scan tool to confirm that the sensor is generating pulses at expected frequencies during vehicle operation.
• Common Issues: A missing or erratic pulse signal may indicate a damaged sensor, faulty wiring, or misalignment. Replacing the sensor typically resolves such problems.
