Long-range sensing made possible with built-in optical lens Stable long-term sensing Enhanced worksite-friendly installability
For the first time in the industry, an
optical ‘double coupling lens’ has been
incorporated directly into the fiber
sensor itself. This lens maximizes the
light emission efficiency, resulting in a
tremendous improvement in the
sensing range. Sensing ranges with
small diameter fibers and ultra-small
diameter fibers, which have become
very popular in recent years due to the
miniaturization of chip components,
have been increased by 50 % over
previous values achieved with other
amplifiers.
The newly developed four-chemical
emitting element that uses the FX-301
(red LED type) suppresses changes
over long periods of time as much as
possible, so that a stable light emitting
level is maintained. There is very little
element deterioration so that stable
and accurate sensing can be
maintained over long periods.
Our new fiber cutter utilizes a specially
developed two-in-one fiber attachment
that now makes it possible to cut two
fibers simultaneously to exactly the
same length. Also, since the fibers can
be attached to the amplifier while
being fixed in position in the two-in-one
fiber attachment, sensitivity changes
due to variation in the amount of fiber
insertion do not occur.
Selectable response time
We offer 4 selectable levels to
correspond with various applications:
the response time 150 !s FAST mode,
the LONG mode, perfect for adverse
environments, and the S-D mode,
especially made for minute detection.

Even beginners can quickly learn how to use the MODE NAVI
MODE NAVI uses six indicators to display the amplifier’s basic operations. The current operating mode can be confirmed at a
glance, so even a first time user can easily operate the amplifier without becoming confused.
Easy maintenance, as main
and sub units are identical
Both main and sub units utilize the same
amplifier body. This feature allows for
easy mounting in the side-by-side
configuration. The main and sub unit
functions are distinguished only by the
proper use of 3-core main cable and the
1-core sub cable. Moreover, by utilizing
the same body for both main and sub
units, inventory management and
maintenance is simplified.
Wiring- and labor-saving design allows side-
by-side configuration for up to sixteen units
Up to sixteen amplifiers can be
connected in a side-by-side configuration.
As the sub cable contains only one output
line, a great amount of wiring and space
can be saved. Also, special ‘sliding’
connectors have been provided for all
main and sub cables, which can be
detached merely by releasing the lock
and pulling directly back, without having
to slide the amplifier body to the side.
Using this connector system, only a
minimal amount of space is required for
regular maintenance.
The use of only two switches makes for very simple operations
Only two switches, the large jog switch and the large MODE key, are required for
operation. Depressing the large MODE key sets the ‘mode selection’ and ‘mode
cancel’ functions. The large jog switch is used to select from the detailed functions
available within each mode, as well as to change numerical values after the mode
has been chosen.
Polyethylene packaging
Environmentally friendly packaging
With regard to effects on the environment,
we only utilize the simplest of packaging
methods greatly contributing to the reduction
in wastes generated by your worksite.
Also, the bags are made of polyethylene, a
substance that doesn’t give off polluting
gases when burned.

4 types of light sources available
In addition to our red LED (four-chemical
emitting element) type, the blue, green,
and infrared LED types are also provided
to correspond to your specific application.
Easy code input setting
Every function can be directly set merely by the input of a four digit code (numbers) from the code table. This convenient
feature is easy to set up.
In the event that settings are accidentally changed at the operating site, merely entering the correct code can restore the
original settings. This results in easy and quick maintenance.
Equipped with each type of timer
These sensors are equipped with 3
types of timers, ON-delay, OFF-delay,
and ONE SHOT, for compatibility to
variegated environments.
ON-delay timer
This function is useful for sensing only
objects taking a long time travel.
OFF-delay timer
This function is useful when the
connected device has a slow response
time.
ONE SHOT timer
This function is useful when the input
specifications of the connected device
require a signal of fixed width.
Optical communication function lets
multiple sensors be adjusted all at once
The optical communication function
allows the data that is currently set to
be copied and saved all at once for all
amplifiers connected together from the
right side. This greatly reduces
troublesome setup tasks and makes
setup much smoother.
Selectable cable length
Made available are 3 lengths, 1 m 3.281 ft,
2 m 6.562 ft, and 5 m 16.404 ft, to suit
your application requirements. This helps
reduce the waste caused by cutting cables
and lightens the installation workload.
Invertible digital display
The digital display can be inverted as per its orientation once mounted onto the amplifier.

APPLICATIONS
Workpieces detection
This standard type of FX-301 using red light
has a four-chemical emitting element for
stable sensing over long periods.
Sensing semi-transparent stickers
The blue LED type greatly reduces the
dampening rate, making it ideal for delicate
sensing.
Sensing register marks
The green LED type can accurately
discriminate between red and yellow, that
cannot be easily detected using red LED
type.
Sensing film meandering
Infrared LED type is ideal for sensing
environments with light restrictions, such as
places where light-sensitive film is being
handled. (The emission peak wavelength:
940 nm 0.037 mil.) It includes full-auto
teaching function which allows sensitivity to
be set without stopping the workpiece line.
Detecting chip component
Because of low light intensity fluctuations
when detecting minute moving objects,
decrease the hysteresis in PRO mode and
accurate sensing will be possible in high-
speed mode. This method is optimal for chip
component verification in taping equipment.
Detecting register marks on a
transparent sheet
When detecting registration marks on
transparent film with a thru-beam type, the
S-D (reduced light intensity) mode will
enable minute light intensity fluctuation
sensing.

Notes: 1) Please take care that the sensing range of the free-cut type fiber may be reduced by 20 % max. depending upon how the fiber is cut. In addition, the infrared
type is easily affected by humidity, so contact our office if using these sensors in environments with high humidity or where humidity levels can fluctuate.
Notes: 2) The minimum sensing object size is the value for red LED type. Please contact our office for information on the minimum sensing object size if using
amplifiers other than red LED type.
The optimum condition is the condition when the sensitivity is set so that the sensing output just changes to light incident operation in the object absent
condition.
Notes: 3) Sensing range for a 2 m 6.562 ft long fiber. A 10 m 32.808 ft long fiber will cause damping of the beam and cannot be used.
Notes: 4) The fiber cutter is not supplied as an accessory with FT-NB8 and FT-N8. Please order it separately.

Notes: 1) Please take care that the sensing range of the free-cut type fiber may be reduced by 20 % max. depending upon how the fiber is cut. In addition, the infrared
type is easily affected by humidity, so contact our office if using these sensors in environments with high humidity or where humidity levels can fluctuate.
Notes: 2) The minimum sensing object size is the value for red LED type. Please contact our office for information on the minimum sensing object size if using amplifiers other than red LED
type. The optimum condition is the condition when the sensitivity is set so that the sensing output just changes to light incident operation in the object absent co ndition.
Notes: 3) The fiber cable length practically limits the sensing range to 3,500 mm 137.795 in long.

Notes: 1) The sensing range is specified for white non-glossy paper (FD-B8, FD-5, FD-FM2, FD-FM2S, FD-FM2S4, FD-N8, FD-T80, FD-S80 and FD-R80:
400400 mm 15.74815.748 in, FD-T40, FD-N4, FD-NFM2, FD-NFM2S, FD-NFM2S4,FD-SNFM2, FD-SFM2SV2 and FD-V41: 200200 mm
7.8747.874 in) as the object.
Notes: 2) Please take care that the sensing range of the free-cut type fiber may be reduced by 20 % max. depending upon how the fiber is cut. In addition, the
infrared type is easily affected by humidity, so contact our office if using these sensors in environments with high humidity or where humidity levels can
fluctuate.
Notes: 3) The minimum sensing object size is the value for red LED type at maximum sensitivity. Please contact our office for information on the minimum sensing
object size if using amplifiers other than red LED type.
Also, note that the corresponding setting distance is different from the rated sensing distance.
Notes: 4) The fiber cutter is not supplied as an accessory with FD-N8 and FD-N4. Please order it separately.
