OMRON's Unique Algorithm Provides Superior Reading Ability for Direct
Part Marking codes
Removal of Printing Irregularities or Noise
You can apply up to three of the four unique filters developed by
OMRON in the desired order to remove printing irregularities and
noise, in order to achieve a stable reading.
Types of Filtering
Smooth: Smoothen the image.
Erosion: For white codes, reduces the cell size.
Effective for reading separated dot codes.
Dilate: For white codes, increases the cell size.
Effective for reading codes with cell spreading.
Median: Removes noise.
Erosion and dilation can be combined to connect dots without changing
the dot thickness.
Automatic Parameter Adjustment Until Reading is Successful
Code Readers must be able to read codes even for poor printing
conditions. You can automatically retry reading while changing the
exposure time and other reading conditions, even for changing
workpieces or environments, to enable a stable reading.
The following retry functions are provided.
Retrying the Specified Number of Times with the Same Conditions
Reading is performed the specified number of times for the same scene.
Retrying While External Trigger Is Input
Reading is performed until successful, as long as an external level
trigger is input.
Retrying While Changing the Shutter Speed
Reading is performed for the same scene while changing the exposure
time in stages.
Retrying While Changing the Reading Conditions
When reading DPM codes, inconsistencies in printing conditions can
result in NGs if reading is performed with only one set of reading
The FQ-CR allows you to register up to 32 sets of reading conditions
as scenes and retry reading while changing the scenes in order.
The system automatically determines the scenes with the highest usage
rates and changes the order to start with them to flexibly handle
changes in reading conditions.
Of course you can specify a fixed order if required.
Register 32 sets of reading conditions.
Rapidly switch to the optimum reading conditions.
Easy Confirmation of Code Quality
Code Error Correction Position Display
Red circles are displayed on cells for which the code was corrected on
This clearly shows where the code quality was poor.
Stable Reading Functions Packed into a Compact Body
Reads Codes Even with Low Contrast
The wider the field of view, the more difficult it is to maintain
consistent lighting within the field, causing errors in reading. The
built-in LEDs of the FQ-CR Series use a unique OMRON DR optical system
for effective light usage to maintain consistent lighting within the
field of vision at a brightness that is four times that of previous
Cuts Light Interference
The HDR (high dynamic range) function minimizes the influence of
changes in lighting conditions and light reflection. This enables
stable inspections even for materials that are difficult to light
evenly, such as metal parts or glossy films, or in locations subject
to external light interference.
Cuts Specular Reflections
A polarizing filter is included to cut specular reflection from glossy
surfaces. This enables stable code reading even for metallic or other
Communications with Host Devices
The compact body also provides an Ethernet connector so that you can
transfer read data and images via Ethernet. Smoothly transfer data to
PLCs, computers, or other host devices.
Essentially, Simple Enough for Anyone to Set Up
Setup is as easy as displaying codes on the monitor and registering
settings with a simple procedure.
Then, the FQ-CR will automatically tune the settings to achieve the
Two Set-up Tools
Use the convenient Touch Finder for on-site settings and control panel
installations, or use a set-up tool on a computer.
PC Tool (Free)
After purchasing the Code Reader, you can download the PC Tool free
from the memberís website.
Menu Displays in Nine Languages
The nine language support for menus means that you can easily
introduce systems into factory sites in other countries.
In addition, you can easily change the language on a menu.
Navigation menus for operating procedures from image adjustment
through to testing and starting operation are provided so that even
beginners can operate the Code Reader.
Flexible System Configuration
Connect Up To Eight Code Readers
The flexibly manageable platform can be used for simple
configurations with one Code Reader for complex configurations with
multiple Code Readers reading from different directions.
Up to eight Code Readers can be controlled from the Touch Finder
Code Quality Management
The FQ-CR2 contains state-of-the-art algorithms that enable the
reading of codes even with poor reading quality. However, even if the
code quality continues to deteriorate for some reason, auto-correction
and retrying are used to enable reading, making it impossible to tell
where quality was lost simply from the OK/NG reading information.
Here, you can use the cell recognition rate information. The cell
recognition rate changes with code printing quality, position
inconsistency, installation conditions, and noise. You can log the
cell recognition rate and image together to manage quality trends. The
logging of recent results is useful for testing when commissioning a
line. Run through some sample products and log the cell recognition
rate. You can then display the results in a time-based graph to see
how much leeway there is in reading performance.
*For the FQ-CR1, the number of detected characters is logged instead
of the cell recognition rate.
Cell recognition rate
Up to 10 million measurement values or more (for a 4-GB SD card)
Up to 10,000 images or more (for a 4-GB SD card)
Logging of Recent Results
Displays the most recent 1,000 cell recognition rate in graph form.
Automatic Notification of NGs
If you leave the Touch Finder installed on-site, the recent NG sensor
display is very useful. Even if you are monitoring more than one Code
Reader with the Touch Finder, the display automatically changes to the
Code Reader where an NG occurred so that you can quickly confirm
