This is the Futaba RPM sensor (optical type) for Futaba telemetry systems.
Includes: RPM sensor with attached cable, plastic mounting bracket, two pieces of double-sided foam tape, instruction sheet and warranty sheet
Requires: Connection to S.BUS 2 system
Note: This sensor will only work with S.BUS 2-compatible devices.
Helicopters: Because of the large rotor diameter, use of this sensor on a helicopter is not recommended. A magnetic sensor, such as the Futaba Magnetic RPM Sensor 18MZ is suggested.
Brightness: Adequate light is needed for this sensor to operate properly. Conditions such as dusk, dawn, clouds, indoor operation, poor angle-of-reflection off of propeller or fin, etc., will result in a measurement of 0 RPM.
Installation: It is recommended that the sensor be mounted at or less than 150mm (6") from the object whose rotation speed is being measured. The closer to the object the sensor is mounted, the more reliable the measurements will be.
Set-up: The default slot number for this device is 2. Information on changing the slot number can be found in the transmitter manual. This device 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/fins: The number of blades on the object whose RPM is being measured is two. If the object has more blades or fins, please consult your transmitter manual for information on changing this number.
