Metzger 0900126sensor wheel speed

Product Overview

The Metzger 0900126 is a high‑performance wheel speed sensor designed to deliver precise and reliable data for vehicle braking, traction control, and stability systems. Engineered with advanced Hall effect technology, it converts the rotational motion of a wheel into an electrical signal that can be interpreted by modern automotive electronic control units (ECUs).

Key Features

• Robust Construction: The sensor housing is made from high‑strength aluminum alloy, providing excellent resistance to vibration, impact, and harsh environmental conditions.
• Wide Temperature Range: Operates reliably between –40 °C and +120 °C, ensuring consistent performance in extreme climates.
• High Signal Accuracy: Generates a precise square‑wave output with minimal noise, enabling accurate wheel speed calculations even at high vehicle speeds.
• Low Power Consumption: Consumes less than 10 mA during operation, reducing the load on the vehicle’s electrical system.
• Compact Design: Small footprint allows easy integration into existing wheel hub assemblies without requiring major modifications.
• Long Service Life: Designed for a lifespan of over 200,000 km under normal operating conditions.

Technical Specifications

Application Areas

The Metzger 0900126 is ideal for a wide range of vehicles and systems:

• Anti‑Lock Braking System (ABS): Provides real‑time wheel speed data to prevent wheel lockup during emergency braking.
• Traction Control: Helps maintain optimal traction by monitoring wheel slip.
• Electronic Stability Program (ESP): Contributes to vehicle stability by detecting differences in wheel speeds.
• Vehicle Dynamics Monitoring: Used in advanced driver assistance systems (ADAS) for lane‑keeping and collision avoidance.
• High‑Performance Vehicles: Suitable for sports cars, SUVs, and commercial vehicles that require precise speed sensing.

Installation Guidelines

Proper installation is critical to ensure accurate sensor performance:

1. Remove the Wheel Hub: Carefully detach the hub assembly following manufacturer instructions.
2. Align the Sensor: Position the sensor so that its magnetic field aligns with the wheel’s toothed rim or gear.
3. Screw Securely: Tighten mounting bolts to the specified torque value (typically 20–25 Nm).
4. Connect Wiring: Use shielded cables and secure connectors to prevent signal interference.
5. Test Signal Integrity: Verify the square‑wave output using an oscilloscope or diagnostic tool before reassembling the wheel.

Maintenance Tips

• Inspect for physical damage after any collision or impact event.
• Check wiring insulation regularly to prevent corrosion or short circuits.
• Ensure that the sensor housing remains free of debris and moisture.
• Replace the sensor if diagnostic codes indicate a malfunction or loss of signal.
