Accurately measure the motor rotation speed with this optical probe.
This optical RPM probe is compatible with the RCbenchmark Series 1520.
Depending on the thickness of the motor, you can adjust the position of the optical RPM probe with a different combination of spacers. Compared with the previous version, it also has higher reliability and accuracy.
The RCbenchmark Series 1520 already comes with an electrical RPM probe but is not always reliable. Use this optical probe if you have issues with the electrical probe.
