By knowing your motor's RPM, you will have more control over efficiency and the ability to ensure a safe operating range. JEGS Impulse Motor Speed Sensor mounts to the tail shaft of many motors for the most accurate RPM measurement.

Easy to install, this Speed Sensor simply connects to your system with the 6 ft. wiring harness, while the included bracket and hardware mount the Hall Effect Sensor and Exciter Ring to the tail shaft.

Keep your motor turning less than max RPM and closer to its most efficient operation to ensure your EV-investment will last for years to come.
