SBS-01RO

Instruction Manual

Thank you for purchasing Futaba's SBS­01RO 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.

Range : 360 ～ 300,000RPM/blades

For Helicopter

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-01RM magnetic
sensor be utilized for helicopters.

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 me

■ 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.

Wh en mou nting th e SB S- 01 RO to th e

󾾙

fuselage, be sure there is som

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 operati on 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 t he SBS-01RO with anythi ng

󾻭

other than an R/C model.
Don't make different connecti on from a

󾻭

manual.

■ It will break down, if different connection is made.

Wiring

The SBS-01RO may only be used
with telemetry enabled receivers
that o󱐯er S.BUS 2 port. Please refer
to the manual(s) that accompanied
your transmitter and/or receiver for
proper connection methodology.

Brightness

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.

ID Number

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.

Installation

● Sensor Mounting Example

[ Airplane ] [ Helicopter ]

Use strong double-sided tape
or screws to mount to the
fuselage of an airplane.

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.

Slot Number Setup

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.

It attaches to the position which
is rotation within the limits of
a main rotor and with which a
stabilizer does not interfere.

Number of blades

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
