PRECAUTIONS FOR PROPER USE
Fiber
Narrow beam type fiber mounting
Take care that, since the aperture angle of this product is very
narrow, the beam may not be received depending upon the setting.
At the time of installation, determine a reference plane, as shown in
the figure below, and taking sufficient care against beam
misalignment or tilt, install the emitting and receiving fibers so that
they are parallel.

FT-KV8 / FT-WKV8
Thru-beam type wide beam fiber mounting
Take care that, since the aperture angle of this product is
very narrow, the beam may not be received depending
upon the setting.
At the time of installation, determine a reference plane, as
shown in the figure below, and taking sufficient care
against beam misalignment or tilt, install the beam-
emitting and receiving fibers so that they are parallel.
Install the fiber using M3
countersunk head screws.
The tightening torque should
be 0.3 N m or less.
Further, when using the fiber
at places having intense
vibrations, use a screw-
locking adhesive, etc.
If mineral oil or solvent containing mineral oil component
adheres to the sensing surface, the lens may be
deformed. Take sufficient care to handle them.
Method of fixing fiber cable
If fixing the fiber cable in position, make sure that it is set in
a manner as shown below, so that no load is applied on the
fiber. (Excluding FT-H35-M2, FT-H35-M2S6, FD-H35-M2
and FD-H35-M2S6)

.
Connection with reflective coaxial type fiber
With reflective coaxial type fiber, insert the center fiber
cable (single-core) into the beam-emitting inlet and the
outer fiber cable (multi-core) into the beam-receiving inlet.
FD-H35-M2 or FD-H20-M1 is marked 'P' on the beam-
emitting fiber cable and 'D' on the beam-receiving fiber cable.
FD-WG4, FD-WSG4 and FD-G4, FD-G6, FD-G6X are
composed of beam-emitting and beam-receiving fiber
cables that are different in diameter.
FD-G500, FD-EG1, FD-EG2, FD-EG3, FD-E22,
FD-H20-21 and FD-ENM1S1 are marked P on the
beam-emitting fiber cable.
Notes: 1) In case the fiber cables are not inserted to a position where they
stop, the sensing range reduces.
Notes:
2) Before connecting fiber cables to the amplifier, mount the fiber
attachments on their ends.
Fiber cable bending radius
If the fiber cable is bent at a smaller bending radius than allowable
bending radius, the sensing range decreases due to beam attenuation.
For a allowable bending radius of 25 mm (0.984 in)
How to bend sleeve
The bending radius must be R10 mm
Please bend gradually using the fiber bender (FB-1) or a
round bar of "20 mm
Note: Do not bend the sleeve of side-view type, narrow beam type, narrow-
view type and ultra-small diameter type fiber.
Use of heat-resistant type fiber
Use by keeping 150 mm
resistant fiber cable part at normal temperature.
Protect the amplifier from heat radiation or hot air.
With the 350 C
surface of the fiber head or the spiral may be discolored
by heat. However, this does not affect its performance.

Note: Please note that the 350 °C
heat-resistant fibers, vacuum-
resistant and chemical-resistant
fibers cannot bend less than the
allowable bending radius.
