Vemo V20-72-0091 Brake

Overview

The Vemo V20-72-0091 Brake Sensor is a high‑performance wheel speed detector designed for automotive safety systems such as ABS, ESP, and traction control. It delivers precise rotational data to the vehicle’s electronic control unit (ECU), enabling rapid response during braking events.

Key Features

• High Accuracy: Measures wheel speed with a tolerance of ±0.5 % across the full operating range.
• Wide Temperature Range: Operates reliably from –40 °C to +125 °C, suitable for harsh automotive environments.
• Compact Design: Small footprint allows installation in tight spaces behind the wheel hub.
• Robust Construction: Sealed housing protects against dust, moisture, and vibration.
• Low Power Consumption: Optimized for minimal draw from the vehicle’s electrical system.

Technical Specifications

Application Areas

The V20-72-0091 is engineered for integration into modern vehicles that require reliable wheel‑speed input. Typical applications include:

• Anti‑Lock Braking Systems (ABS)
• Electronic Stability Programs (ESP)
• Traction Control Modules
• Vehicle Dynamics Management
• Advanced Driver Assistance Systems (ADAS) that rely on wheel‑speed data

Installation Guidelines

1. Remove the existing sensor: Disconnect the battery, detach the wheel hub cover, and carefully unscrew the old sensor.
2. Align the new sensor: Position the V20-72-0091 so that its magnetic pole aligns with the wheel’s rotating element (usually a toothed rim or magnet).
3. Screw in place: Tighten to manufacturer torque specifications.
4. Reconnect wiring: Ensure proper polarity and secure connections.
5. Test functionality: Verify signal output with a diagnostic tool before reassembling the wheel cover.

Diagnostic Features

The sensor’s Hall‑effect output can be monitored for:

• Signal amplitude consistency
• Noisy or intermittent signals indicating mechanical wear
• Loss of signal suggesting a broken magnet or wiring fault

Compatibility

The V20-72-0091 is compatible with a wide range of vehicle platforms that use standard wheel‑speed sensor interfaces. It has been validated for use in rear‑wheel configurations on models such as the BMW X5, where precise rear‑wheel data is critical for stability control.

Quality Assurance

Each unit undergoes rigorous testing:

• Environmental Stress Screening (ESS): Thermal cycling and vibration tests to ensure durability.
• Electrical Performance Verification: Signal integrity checks across the full operating range.
• Functional Validation: Integration testing with vehicle ECUs to confirm correct data transmission.

Conclusion

The Vemo V20-72-0091 Brake Sensor delivers dependable wheel‑speed measurement essential for modern safety systems. Its compact size, robust construction, and precise output make it a reliable choice for automotive manufacturers and aftermarket installers alike.
