Features
OMRON's Unique Algorithm Provides Superior Reading Ability for Direct Part Marking codes
Filter Function for 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.
| Smooth | Smoothen the image. | Median | Removes noise. | |
| 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. |
Erosion and dilation can be combined to connect dots without changing the dot thickness.
Retry Function with 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 settings. 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.
Rapidly switch to the optimum reading conditions.
Stable Reading Functions Packed into a Compact Body
High-power LEDs - Read 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 models.
HDR Function - 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.
Polarizing Filter - 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 glossy surfaces.
Ethernet Connection - 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.
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 set-up console.
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.

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 conditions.
