Futaba Telemetry Sensor Optical RPM SBS-01RO

This sensor, when used in conjunction with the Futaba telemetry enabled transmitter/receiver, is used to indicate the number of rotations per minute of the item to which it is attached via the use of light.

The SBS-01RO is not optimal for helicopter use due to the large distance between the rotor and sensor, as a result, the reading can be unstable. We recommend the SBS-01R Mmagnetic sensor be utilized for helicopters.
