INSTALLATION
CONTENTS
Magnet
There are two sides (poles) to the
magnet, to properly install the magnet
the correct side (pole) of the magnet
must be facing the sensor.
To determine the correct orientation,
plug the SBS-01RM into the receiver
and power the receiver up. The LED on
the SBS-01RM will glow red.
Next bring the magnet within 2mm of the
sensor, if the correct side is facing the
sensor the LED will turn off. It it remains
lit, turn the magnet over to assure it
turns the LED off. Mark this side of the
magnet with a permanent marker to use
as reference during installation.

Instruction Manual
Thank you for purchasing Futaba's SBS-
01RM RPM sensor. This sensor, used
in conjunction with a telemetry enabled
transmitter/receiver, is used to indicate the
number of rotations (engine, a motor, 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-01RM is designed for use
with Futaba telemetry systems .

● Operation Check
Power up the receiver (transmitter off) with the
SBS-01RM connected to the S.BUS2 port of
the receiver. Move the magnet so that it aligns
with the sensor. If the LED on the SBS-01RM
turns off the installation is correct.

WARNING
To utilize the SBS-01RM sensor, connect it to
the S.BUS2 port of the Futaba telemetry
enabled receivers.
■ The SBS-01RM 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.
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.
Mount the sensor in accordance with the
installation method described below.
■ If the SBS-01RM drops out during flight, it cases erratic
operation or loss of control.
Vibration-proof the PC board and mount the
SBS-01RM 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-01RM 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.
Do not use the SBS-01RM with anything other
than an R/C model.
Don't attach the magnet to a propeller.
■ A propeller is damaged and there is a possibility of carrying
out a large injury by a scattering thing.
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-01RM may only be used with
telemetry enabled receivers that offer S.BUS
2 port(s). Please refer to the manual(s) that
accompanied your transmitter and/or receiver
for proper connection methodology.

The distance between the sensor and the
magnet must be 1-2mm.
Drill a hole with a 4.1mm
diameter 1.5-1.7mm deep
to mount the magnet. Use
a non-metal bearing epoxy
adhesive to secure it in place.
