Futuba SBus RPM Optical Telemetry Sensor

Futuba SBus RPM Optical Telemetry Sensor


The Futaba SBus FUTSBS01RO RPM Optical Telemetry  Sensor makes it easy to get the RPM information you need. Simply plug into the S.Bus2 slot on a telemetry-enabled receiver, and the Bi-directional communication will allow the data to be transmitted directly to your Futaba T-FHSS or FASSTest transmitter. Use this sensor to indicate the rotation speed of a propellor, rotor or other component. Nothing needs to be attached to the component since the sensor uses available light reflected off that component. 



1 x RPM sensor with attached cable

1 x Plastic mounted bracket

2 x Pieces of double sided foam tape

1 x Instruction sheet

1 x Warranty sheet 



Connection to S.Bus 2 System



Because of the large rotor diamaters the use of this sensor on a helicopter is not recommended. A magnetic sensor like the Futuba Magnetic RPM Sensor 18MZ (FUTM0852) is suggested.


Brightness: Adequate light is needed for this sensor to operate properly. Conditions such as dawn, dusk, clouds, indoor operation, poor angle of reflection off the propellor or fin etc will result in a measurement of 0 RPM.



It is recommended that the sensor be mounted at or less than 150mm from the object whose rotation speed is being measured. The closer the sensor is mounted to the object the more reliable the measurements will be.



The default slot number for this device is 2. Information on changing the slot number can be found in the trasmitter manual.  This sensor also has a default S.Bus 2 ID number which will need to be changed if more than one SBS-01RO sensor is attached to the same S.Bus network. The default ID number can be found on the side of the unit.


Number of blades:

The number of blades on the object whose RPM is being measured is two. If the object has more blades please consult your transmitter manual for information on changing this number.
