ABS 30350 Wheel Speed Sensor

ABS 30350 Wheel Speed Sensor Overview

The ABS 30350 Wheel Speed Sensor is a critical component of modern automotive braking systems, designed to monitor the rotational speed of each wheel and provide real‑time data to the Anti‑Lock Braking System (ABS) controller. By detecting rapid changes in wheel velocity, this sensor enables the ABS module to modulate brake pressure, preventing wheel lockup during emergency stops or on slippery surfaces.

Key Functionalities

• High Accuracy Wheel Speed Measurement: Utilizes a magnetic Hall‑effect principle to generate precise electrical pulses proportional to wheel rotation.
• Robust Signal Integrity: Features built‑in filtering and noise rejection to maintain reliable operation in harsh automotive environments.
• Wide Operating Temperature Range: Engineered to function effectively from –40 °C to +125 °C, ensuring performance across diverse climates.
• Low Power Consumption: Optimized for minimal electrical draw, preserving battery life and reducing load on the vehicle’s power supply.

Technical Specifications

Installation Guidelines

1. Safety First: Disconnect the vehicle battery and ensure the wheel is securely supported before beginning work.
2. Remove Old Sensor: Detach the existing sensor by loosening the mounting bolts and carefully disconnecting the wiring harness.
3. Prepare New Sensor: Verify that the sensor’s magnetic strip aligns correctly with the wheel hub’s toothed ring. Clean any debris from both surfaces.
4. Mount Sensor: Secure the ABS 30350 using the supplied mounting hardware, tightening bolts to manufacturer specifications.
5. Reconnect Wiring: Attach the sensor harness, ensuring a snug fit and proper polarity.
6. Test Functionality: Reconnect the battery, start the engine, and verify that the ABS indicator lights on the dashboard behave normally during braking tests.
