PRECAUTIONS FOR PROPER USE
Fiber
Cautions for FX-MR5 side-view zoom lens usage
The spot diameter and the sensing range are adjustable
by the screw-in depth as follows.
After FX-MR5 is set on the fiber
head at the desired depth, tighten
the attached nut NT-FX-MR5
securely.
The tightening torque should be 0.5 N m or less when
tightening FX-MR5 with a screw.
Fitting protective tube
The threaded head free-cut fiber can be fitted with a
protective tube.
Fitting
1 Insert the fiber cable into the protective tube from the
sleeve side.
2 Turn the fiber head to screw it on the inner thread of the
sleeve.
Mounting
The maximum tightening torque should be as given below.

Sleeve part
Tightening torque:
0.58 N m or less
Note: The fiber cable must be longer than the protective tube by 30 mm
1.181 in
or more to connect it to the amplifier. Make sure to measure
the length required before cutting.

Others
Do not use the fiber at places having intense vibrations, as
this can cause malfunction.
Keep the fiber head surface
intact. If it is scratched or
spoiled, the detectability will
deteriorate.
Do not expose the fiber cable
to any organic solvents.
(
Excluding
chemical-
resistant type fiber
Do not use the fiber head in places where it may come in
direct contact with water. A water drop on the fiber head
deteriorates the sensing.
Ensure that any strong extraneous light is not incident on
the receiving face of the fiber head.
Do not apply excessive tensile force to the fiber cable.
Take care that the sensor is not directly exposed to
fluorescent light from a rapid-
starter lamp or a high frequency
lighting device, as it may affect the
sensing performance.
Since the sensing portion of the wide beam or narrow
beam fiber is concave shaped, take care that dust or dirt
does not collect on it.
In case it does collect, wipe it with a dry soft cloth.
