SOLUTION
PROBLEM
MODEL
It used to be hard to detect the
presence or absence of stickers
because their mounts are thick (with
white colors), and light does not go
through.
BENEFIT 1
Digital fiber sensor:
FX-301
Rectangular head fiber : FT-Z8
Stable detection because light even goes through thick paper with
strong light emitted.
TIPS: FX-301 emits a lot of amount of light by adopting the double-coupling lens. Light goes through
even thick paper and can detect the presence or absence of thick paper (white) easily.
BENEFIT 2
Saving space
TIPS: FT-Z8 is a ultra thin head with a size of W8.5 x H12 x D3mm. You can even install it at a
limited space since it is a front sensing type. You can save space since the fiber cable can be bent
sharply with a bending radius of R4mm.
BENEFIT 3
Easy installation
TIPS: Installation and beam-axis alignment can be done easily since FT-Z8 is a rectangular head
with M2 screws at two points.
PACKAGING, PHARMACEUTICAL AND FOOD PROCESSING
Hard to detect the
presence or
absence of stickers
since mounts of the
stickers are thick.

BENEFIT 1
MODEL
Digital fiber sensor:
FX-301
High precision fiber:
FD-G4
Zoom lens:
FX-MR5
Possible to detect due to the fiber with the zoom lens
TIPS: It is possible to detect with a lot of difference between light intensity when having notches and
the one when not having notches because the minimum spot diameter is 0.5mm (screw-in depth:
8mm / distance to focal point: 13mm.)
BENEFIT 2
Saving space
TIPS: You can install it at a limited space because FX-MR5 is a side-view type.
BENEFIT 3
SEMICONDUCTORS & ELECTRONIC COMPONENTS
PROBLEM
With fixed-focus reflective type fiber
of other companies, stable detection
is impossible. This is caused as a
result that the difference between
light intensity with notches and the
one without notches is small because
of big spot light.

PREVIOUS METHOD
SOLUTION
PROBLEM
MODEL
Conventional products used to detect
thread breakage by detecting its
tension. However, stable detection
was not possible.
BENEFIT 1
OTHERS
Stable detection was
not possible although
conventional sensors
used to detect
tension.
Digital fiber sensor:
FX-301
Array fiber:
FT-AFM2E
Compact
TIPS: FT-AFM2E is compact with a size of W5 x H15 x D15mm.
BENEFIT 2
Easy installation
TIPS: Installation is easy since FT-AFM2E is rectangular.
BENEFIT 3
FIBER SENSOR
Detection of thread breakage of industrial sewing machines
Prevents chattering with delay timer
TIPS: Delay timer of FX-301 prevents chattering due to thread fluttering, and stable detection is
possible.

PROBLEM
MODEL
Conventional products can detect it
only from a far distance because
there is a robot around sensing
objects.
BENEFIT 1
Digital fiber sensor:
FX-301
M4 fiber for general use:
FT-FM2
Zoom lens:
FX-MR2
Expansion lens:
FX-LE1
Stable detection even with long sensing range
TIPS: Long sensing range is possible by setting FX-301 to the LONG mode, attaching FX-MR2 to an
emitter of the fiber head and making screw-in depth deeper.
BENEFIT 2
High resolution
TIPS: The LONG mode of FX-301 has slower response time, but it allows a better sensing ability and
stable detection of the difference in the amount of light.
NOTE 3
BENEFIT
This application uses the attachment lens in a different way from general usage.

PROBLEM
MODEL
Equivalent products of other
companies could not detect quartz
crystal (glass) because it is
transparent.
BENEFIT 1
Ultrahigh-speed laser displacement sensor
Sensor head
Controller
HL-C105B
HL-C1CM
You can detect quartz crystal and glass.
TIPS: HL-C108B and HL-C105B are specular-reflective types, which are the best for detection of
objects with mirror surface and transparent objects.
BENEFIT 2
Accurate detection of micro-objects.
TIPS: Resolution of 1um and linearity of +/- 0.1% F.S. allows high-precision detection.
BENEFIT 3
SEMICONDUCTORS & ELECTRONIC COMPONENTS
Impossible to detect
with equivalent
products of other
companies.

competitor’s product.
Computation unit

PROBLEM
MODEL
A digital panel meter was needed to
check if there is warpage from 50 to
200um against wafer (thickness:
800um.)
BENEFIT 1
Sensor head
HL-T1001F
Controller
HL-AC1
Computation unit HL-AC1-CL
It is possible to have a stable detection of warpage of 50um.
TIPS: With the laser beam of
BENEFIT 2
Ultra-compact laser line sensor
1mm, it is possible to detect slight warpage of 50um.
No need for digital panel meter.
TIPS: Connecting a computation unit between controllers can calculate two sensors, and it can be
displayed on the controller. Therefore, there is no need for digital panel meter.
BENEFIT 3
Compliant with the FDA standard.
TIPS: HL-T1001F is compliant with the FDA standard.

Controller
HL-C108B-BK
HL-C1C-M
Stable detection for moving objects is possible by ultrahigh-speed
sampling rate.
TIPS: The fastest sampling rate in the class, 100 us.
BENEFIT 2
Saving cost and space.
TIPS: Possible to connect two sensor heads to a controller. You can save cost and space for one
controller when using two sensors.
BENEFIT 3
Data maintenance is easy.
TIPS: Controller HL-C1C-M is equipped with series input/output by RS-232C. Thus, it is possible to
read and write setting data and read measurement values.

Stable detection for black objects.
TIPS: Possible to detect black objects with little amount of reflective light by a linear image sensor
type.
BENEFIT 2
We cut slight noise, and stable detection for eccentricity measurement
is possible.
TIPS: The noise by quartz that prevents proper measurement on eccentricity was cut by low-pass
filter function, which makes stable measurement possible.
BENEFIT 3
Ultrahigh-speed sampling rate
TIPS: With the fastest sampling rate in the class of 100us, higher-precision detection has become
possible.
ELECTRIC APPLIANCES
With products of
other companies,
stable detection is
not possible because
of effects from a
color of the object
(black) and a shine.
