KUS Electromagnetic RPM Sensor / Pick-Up Sensor – Precise RPM Measurement Directly at the Flywheel
Get absolutely vibration-free, precise, and responsive RPM measurement right on your instrument panel! The original KUS electromagnetic RPM sensor (pick-up sensor) is mounted directly on the engine housing (e.g., on the flywheel housing of your inboard motor). It non-contactedly detects the passing teeth of the gear ring and converts this mechanical motion into a high-precision electrical frequency signal for your KUS tachometer.
This measurement method is the professional and most durable alternative to the inaccurate alternator tap (terminal W), as it operates completely independently of belt slip or battery charge levels.
⚠️ Important Note on Selection (Thread Sizes & Lengths):
To ensure the sensor fits precisely into your engine housing and maintains the correct distance from the gear, please select the appropriate variant from the drop-down menu above. Please check the thread size on your machine (M16) and the required shaft length beforehand.
Advantages & Technical Highlights at a Glance:
- Non-contact inductive technology: Completely wear-free, maintenance-free, and extremely durable, as there are no mechanical components subject to friction.
- Premium stainless steel housing (AISI 316): Completely saltwater-resistant, oil-resistant, and robust against the extreme vibrations and temperatures in the engine compartment.
- Stable signal: Delivers a clean and jitter-free frequency signal to the cockpit even at low RPMs (e.g., when idling during harbor maneuvers).
- IP67 protection rating: The cable exit and the transducer head are fully sealed to be dust- and watertight.
