• Aerospace & Marine: Robust construction makes it fit for propeller speed monitoring in small aircraft or marine propulsion systems.

Installation Guidelines

1. Mounting Position: Place the sensor on a rotating shaft or wheel rim, ensuring the magnetic field is centered over the sensor’s detection area.
2. Electrical Connection: Connect the power supply (12 V DC) and ground to the designated pins. Attach the output line to the control unit’s input pin, using shielded cable to reduce electromagnetic interference.
3. Alignment Check: Verify that the sensor is perpendicular to the shaft axis; misalignment can cause pulse distortion.
4. Secure Fastening: Use M3 screws or the provided bracket to lock the sensor firmly in place, preventing vibration‑induced drift.

Calibration and Testing

To ensure optimal performance, perform a quick calibration routine after installation:

• Baseline Pulse Count: Run the shaft at a known speed (e.g., 1000 RPM) and record the pulse frequency.
• Adjust Software Scaling: Input the measured frequency into your control software to map it accurately to real‑world units.
• Verify Linearity: Test at multiple speeds (e.g., 500, 1500, 2000 RPM) and confirm linear response within ±0.5 % error.

Maintenance Tips

• Regular Inspection: Check for physical damage or corrosion on the sensor housing and connectors every six months.
• Cleanliness: Keep the sensor surface free from oil, dirt, and debris that could interfere with magnetic coupling.
• Electrical Integrity: Inspect wiring for fraying or loose connections; replace any compromised cables immediately.
