• Mounting Type: Standard bolt‑in with integrated mounting flange
• Connector: 4‑pin automotive plug (compatible with most OEM harnesses)

Compatibility and Application

The V30-72-0163 is engineered to fit a wide range of vehicles, particularly those equipped with MERCEDES‑BENZ models such as the W163, ML class, and other front‑wheel or rear‑wheel configurations. Its compact design allows seamless integration into both original equipment (OE) and aftermarket setups.

Performance Highlights

• High Accuracy: Maintains ±0.5 % tolerance across the full operating range, ensuring reliable ABS activation.
• Fast Response Time: Detects wheel speed changes within milliseconds, critical for rapid braking scenarios.
• Robust Construction: Encased in a durable metal housing that resists vibration, shock, and corrosion.
• Low Power Consumption: Designed to draw minimal current, preserving battery life.

Installation Guide

1. Preparation: Disconnect the vehicle’s battery to prevent electrical hazards. Remove the existing wheel speed sensor by loosening the mounting bolts and disconnecting the wiring harness.
2. Positioning: Align the new V30-72-0163 with the sensor slot on the wheel hub or axle assembly. Ensure that the magnetic pole of the Hall‑effect element faces the rotating toothed wheel or gear.
3. Mating: Secure the sensor using the supplied mounting bolts, tightening to the manufacturer’s torque specification (typically 20 Nm).
4. Wiring: Connect the 4‑pin harness to the vehicle’s ECU connector. Verify polarity and continuity before finalizing.
5. Testing: Reconnect the battery, start the engine, and verify that the ABS light remains off during normal operation. Perform a wheel spin test to confirm signal generation.

Maintenance Tips

• Inspect the sensor housing for cracks or dents after any collision event.
• Clean the sensor surface with a soft brush and isopropyl alcohol; avoid abrasive materials that could damage the Hall‑effect element.
• Check wiring integrity periodically, especially in high‑vibration environments.

Benefits for Vehicle Safety

The V30-72-0163 plays a pivotal role in maintaining vehicle stability. By providing accurate wheel speed data:

• It enables the ABS system to modulate brake pressure, preventing wheel lock‑up during emergency stops.
• It feeds into traction control algorithms that limit wheel spin under low‑friction conditions.
• It supports electronic stability programs (ESP) that detect and correct yaw or roll tendencies.
