Liquid adherence-free
fiber tip
Avoids liquid drop adherence
Immune against chemical agents
No metal ionization
Reduces malfunction due to adhering
of a liquid drop.
The fiber is totally covered with fluorine
resin. It can be immersed in chemicals.
The fiber is made of 100 % resin.
Hence, it does not release metal ions.
It can also be safely used in semiconductor manufacturing cleaning
equipment.

Malfunction due to liquid
drop adherence
Heat-resistant up to 125 °C 257 °F and free-cut
It can be used in hot liquids since it is
heat resistant. Moreover, it can be cut
to any desired length.
Principle of detection
When the fiber tip is in the air, as there is a large difference between the air and
the tube refractive indexes, the tube boundary reflects the emitted beam back to
the receiver. On the other hand, when the fiber tip is immersed in a liquid, the
emitted beam scatters from the fiber into the liquid because of the small
difference in the liquid and the tube refractive indexes.

1 Slide part @ of the fiber cutter fully upward till it stops.
2 Insert the fiber cables, mounted in the attachment, till
they stop.
Take care that there are separate fiber cable insertion
holes for "2.2 mm "0.087 in and "1.0 mm "0.039 in
or "1.3 mm "0.051 in fiber cables.
Part@
3 Slide part @ of the fiber
cutter down to cut the fiber
cable.
For "2.2 mm "0.087 in
fiber cable
Notes: 1) The fiber cables should be cut in one stroke.
2) Once a fiber cable is cut off at a hole, do not use the hole again. If
used, it degrades the cut surface quality and the detectability may
deteriorate.
3) The blade cannot be replaced. Please purchase an additional fiber
cutter, if required.
4) Note that the sensing range may be reduced by up to 20 %
depending on the cut condition. Hence, decide the setting distance
by taking sufficient margin.

In the fiber not immersed condition, slowly turn the adjuster
clockwise and find the point

switched ON.
The pointer blinks once at the
point @ . (Note 1)
In the fiber immersed condition, slowly turn the adjuster further clockwise until
the sensor goes into the ON
state again. Once it is
switched on, turn the adjuster counterclockwise a
little and find the point b
where it is switched OFF.
The pointer blinks twice at

Notes: 1) When ‘assist function’ is not used, the pointer does not blink.
Notes: 2) When ‘assist function’ is not used, the middle point of @ and b is
regarded as the optimum sensitivity point.
Notes: 3) In order to protect the mechanism, the sensitivity adjuster idles
when over turned, which may result in a backlash of 1 to 2
divisions.
Notes: 4) Depending upon the sensing conditions, stable sensing may be
possible at a position which is slightly shifted from the optimum
sensitivity point.
Notes: 5) Do not move or bend the fiber cable after the sensitivity adjustment. Detection may become unstable.

• Take care that unclear liquid may not be sensed stably.
• Take care that the tube may stretch by maximum 2 % of
the total length if it is used at a high temperature.
• Bending radius of the fiber cable must be R15 mm R0.591 in
or more (tube: R40 mm R1.575 in or more). However, do not
bend 32 mm 1.260 in length from the tip.
If the bending radius is smaller than the specified value, the
sensing performance may deteriorate.
• 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.
• 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.
