Vemo V30-72-0131 Sensor, wheel speed

Vemo V30-72-0131 Sensor

The Vemo V30-72-0131 is a high‑performance wheel speed sensor designed to deliver precise and reliable data for vehicle safety systems. It is engineered to meet the demanding requirements of modern automotive electronics, providing accurate wheel rotation information that feeds into ABS (Anti‑Lock Braking System), ESP (Electronic Stability Program), traction control, and other critical driver assistance functions.

Key Functionalities

• Wheel Speed Measurement: Captures the rotational speed of each wheel with high fidelity, enabling real‑time monitoring by vehicle control units.
• ABS Integration: Supplies essential input for ABS modules to modulate brake pressure and prevent wheel lock during emergency stops.
• ESP & Traction Control Support: Provides data that helps maintain vehicle stability, especially under slippery or uneven road conditions.
• High Signal Integrity: Features a robust output signal with minimal noise, ensuring reliable communication even in harsh automotive environments.

Technical Specifications

Design Features

The sensor’s compact form factor allows seamless integration into a wide range of vehicle platforms. Its robust housing protects internal components from vibration, moisture, and temperature extremes commonly encountered in automotive applications. The Hall‑effect technology ensures low power consumption while maintaining high sensitivity to magnetic fields generated by the wheel’s rotating elements.

Installation Guidelines

1. Preparation: Verify that the vehicle’s electrical system is de‑energized before handling the sensor. Remove any protective covers or seals from the mounting area.
2. Alignment: Position the sensor so that its magnetic field aligns with the wheel’s rotating disc or toothed ring. Proper alignment guarantees accurate speed detection.
3. Mating: Secure the sensor to the mounting flange using the supplied bolts and torque specifications. Ensure a tight, vibration‑resistant fit.
4. Cabling: Connect the sensor’s output leads to the vehicle’s control unit following the manufacturer’s wiring diagram. Use shielded cables where possible to reduce electromagnetic interference.
5. Testing: After installation, perform a functional test by rotating the wheel and observing the signal on an oscilloscope or diagnostic tool. Confirm that the sensor outputs a clean square wave with correct frequency.
