• Durable Mounting Interface: The sensor features a standardized mounting flange that allows for straightforward installation on most flywheel assemblies, reducing service time and complexity.

Technical Specifications

Design and Construction

The VEMO Pulse Sensor incorporates a high‑precision magnetic core that interacts with the flywheel’s teeth or slots to generate a consistent electrical signal. The sensor housing is constructed from high‑temperature alloy steel, providing excellent resistance to vibration, thermal cycling, and mechanical shock. An integrated thermal compensation circuit ensures that the output remains stable across a wide temperature range, eliminating the need for external calibration.

Installation Guidelines

1. Preparation: Ensure the flywheel is clean and free of debris. Verify that the sensor mounting flange aligns with the flywheel’s mounting points.
2. Mounting: Secure the sensor to the flywheel using the supplied bolts. Tighten to the manufacturer’s specified torque (typically 15 Nm).
3. Electrical Connection: Connect the sensor’s output to the engine control unit (ECU) using shielded cable. Verify polarity and signal integrity with an oscilloscope or diagnostic tool.
4. Testing: After installation, run the engine at idle and observe the pulse frequency. Confirm that the ECU registers correct crankshaft position data.
