Material Composition
Corrosion-resistant housing with sealed internal electronics.
Structural Characteristics
Threaded barrel for easy mounting near gear teeth or tone wheels, with an integrated cable or sealed connector.
Working Principle
Utilizes magnetic or Hall-effect technology to detect passing gear teeth, generating a frequency-proportional pulse signal.
Installation Requirements
Set the correct air gap between the sensor face and the gear tooth. Ensure the mounting surface is clean and flat.
Precautions for Use
Do not expose to high-pressure water jets (exceeds IP44). Keep the sensor face free of metallic debris.
