MP-9100 Magnetic Rotation Detector

The MP-9100 is a durable magnetic rotation detector designed for precise, non-contact RPM measurement. It senses the rotation of gear teeth using electromagnetic induction and is compatible with various tachometers for industrial and field use..

The MP-9100 operates by detecting the periodic magnetic changes caused by gear teeth passing close to the detector’s magnetic core. This alters magnetic flux, generating a frequency-correlated voltage signal proportional to RPM. Its non-contact design prevents mechanical interference or wear, making it especially reliable for harsh conditions.

Available in a broad lineup—including heat- and oil-resistant variants—the MP-9100 adapts easily to many industrial setups. The slightly extended body provides better reach when positioning next to rotating parts. Since it requires no external power, setups are simplified and ideal for rapid testing or tough field environments.

  • Non-Contact Gear Detection – Reads rotational speed by detecting magnetic flux changes as gears pass, requiring no physical contact.

  • Highly Durable – Built with a simple, rugged structure suited for harsh operating environments with vibration, heat, or oil exposure.

  • Wide Range of Versions Available – Offers options such as general-purpose, oil-proof, heat-resistant, compact, and extra-long shapes for diverse applications.

  • Extended Detection Interface – Replaces its predecessor with a slightly longer body for easier positioning near the gear.

  • Power-Free Operation – Generates frequency output without needing any external power—ideal for field measurements.
