Metzger 0900664 Sensor, Wheel Speed

The Metzger 0900664 is a high‑performance wheel speed sensor designed to deliver precise rotational data for automotive braking and traction systems. Its compact form factor and robust construction make it an ideal choice for modern vehicles that demand reliable ABS (Anti‑Lock Braking System) performance.

Key Functionalities

• Accurate Wheel Speed Measurement: Captures real‑time rotational velocity of the wheel, enabling the vehicle’s control unit to modulate brake pressure effectively.
• ABS Integration: Works seamlessly with ABS modules to prevent wheel lockup during emergency braking. The sensor’s signal is fed directly into the ABS controller for instant response.
• High Signal Integrity: Features a robust magnetic pickup that generates clean, low‑noise pulses even under harsh operating conditions such as extreme temperatures and vibration.

Technical Specifications

• Model Number: 0900664
• Type: Magnetic wheel speed sensor (Hall effect)
• Operating Voltage: 12 V DC
• Signal Output: Pulse frequency proportional to wheel rotation rate
• Temperature Range: –40 °C to +125 °C
• Mounting Orientation: Designed for rear‑right wheel installation on Mercedes‑Benz C‑Class (CLK, Coupe, Berline, Break)
• Dimensions: Compact footprint suitable for tight engine bay spaces
• Connector Type: Standard automotive 3‑pin plug compatible with existing ABS harnesses

Installation Notes

The Metzger 0900664 is engineered for straightforward installation. It aligns with the standard mounting points on the rear wheel hub assembly, ensuring a secure fit without requiring extensive modifications. The sensor’s polarity and wiring are consistent with typical ABS modules, allowing technicians to swap it in place of a faulty unit with minimal effort.

Compatibility

This sensor is specifically tailored for use on the Mercedes‑Benz C‑Class, including variants such as the CLK Coupe, Berline, and Break. It matches the OEM specifications for wheel speed detection on the rear‑right side of these models, guaranteeing optimal performance in both day‑to‑day driving and high‑intensity braking scenarios.

Performance Highlights

• Rapid Response: The sensor’s magnetic pickup delivers instantaneous pulse generation, allowing the ABS controller to react within milliseconds of wheel speed changes.
• Durability: Constructed from high‑grade materials that resist corrosion and wear, ensuring long‑term reliability even in demanding environments.
• Low Power Consumption: Operates efficiently at 12 V DC, contributing to overall vehicle energy efficiency.

Applications Beyond ABS

While its primary role is within the ABS system, the Metzger 0900664 can also feed data into other vehicle control modules such as Electronic Stability Control (ESC) and traction management systems. By providing accurate wheel speed information, it supports a range of safety features that rely on precise rotational metrics.

Maintenance Tips

Regular inspection of the sensor’s wiring harness for signs of wear or corrosion can preempt potential failures. Cleaning the sensor housing with a dry cloth removes dust and debris that might interfere with magnetic coupling, maintaining signal clarity over time.

Conclusion

The Metzger 0900664 Sensor, Wheel Speed stands out as a reliable, high‑quality component for modern automotive braking systems. Its precise measurement capabilities, robust construction, and seamless integration with ABS modules make it an essential part of vehicle safety architecture, particularly for the Mercedes‑Benz C‑Class lineup.
