Instruction Manual

Thank you for purchasing Futaba's SBS-

01RO RPM sensor. This sensor, used

in conjunction with a telemetry enabled

transmitter/receiver, is used to indicate the

number of rotations (propeller, rotor, etc. ) of

the item to which it is attached. The number

of rotations of a model in the sky is a system

which can be checked with a transmitter etc.

To maximize your enjoyment, and to ensure

proper sensing, please read through this

manual thoroughly. We also encourage you to

retain the manual for future reference should

the need arise.

●The SBS-01RO is designed for use

with Futaba telemetry systems

WARNING

To utilize the SBS-01RO sensor, connect it

to the S.BUS2 port of the Futaba telemetry

enabled receivers.

■

The SBS-01RO will not function properly if connected to

an S.BUS port or other channel ports.

Be careful of the connector polarity.

■

Because of the case construction, reversing the polarity

may cause trouble or sparking from the wiring.

Mount the sensor in accordance with the
installation method described below.

■

If the SBS-01RO drops out during flight, it cases erratic

operation or loss of control.

Vibration-proof the PC board and mount the

SBS-01RO where it will not be exposed to

fuel and water.

■

Electronic parts are used at the PC board. Take protective

measures against vibration, shock, high temperature, and

so forth.

When mounting the SBS-01RO to the

fuselage, be sure there is some slack in the

wiring cable.

■

If the cable is too tight, vibration may cause the wire to break

or the connector to be dislodged and cause a malfunction.

Always perform an operation check after
assembling.

■

Do not fly until inspection is complete.

Don't touch a sensor during engine motor
rotation.

■

When a rotation portion is touched, there is a possibility

of carrying out a large injury.

Do not use the SBS-01RO with anything
other than an R/C model.

Don't make different connection from a

manual.

■

It will break down, if different connection is made.

Please note that the proper default slot for

this accessory is number 2. Information

on how to change the slot assignment is

included in the transmitter's manual.

The SBS-01RO uses an optical

sensor. To operate properly the

prop or rotor being measured must

be fairly brightly lit. Typically the

sensor will not operate properly

indoors, on cloudy days or in early

mornings/late evenings when the

angle of the light striking the prop

or rotor is bad. When one of these

conditions exist, the RPM will be

displayed as 0.

The distance between the sensor and the

surface of rotation less than 150 mm.

*Mount the sensor as close as possible to the

prop or rotor.

*The color of the prop or rotor could cause the

RPM to not be detected.

*The SBS-01RO only works in sunlight.

Sensor Mounting Example

[ Airplane ]

[ Helicopter ]

The SBS-01RO may only be used

with telemetry enabled receivers

that offer S.BUS 2 port. Please refer

to the manual(s) that accompanied

your transmitter and/or receiver for

proper connection methodology.

T h e S B S -01R O i s n o t o p t i m a l f o r

helicopter use due to the large distance

between the rotor and sensor, as a

result, the reading can be unstable. We

recommend the SBS-01RM magnetic

sensor be utilized for helicopters.

The sensor defaults to two blades. If

the prop/rotor has more than 2 blades

this option must be changed in the

transmitter. (Refer to the transmitters

manual.)

Each sensor has a unique ID number

printed on it. If more than one of the

same type of sensor is utilized in a model,

the ID will need to be input into the

sensor menu of your transmitter.

It attaches to the position which

is rotation within the limits of

a main rotor and with which a

stabilizer does not interfere.

Use strong double-sided tape

or screws to mount to the

fuselage of an airplane.
