This versatile Orange RPM Sensor for brushless motors is suitable for inrunner and outrunner motors and works by detecting the voltage changes in the wires to the motor, and then outputs the RPM signal.

The sensor can be used with :
• Orange short and long range telemetry systems.
• Orange telemetry receivers.
• Flybarless sytems with integtrated governor (such as V-bar) Please pay attention to proper connection of the sensor to the V-Bar unit.
• Data loggers (such as Eagle Tree)  Please pay attention to proper connection of the sensor to the unit.
