Your ID reader has to be able to see the code in order to extract the data. When codes are printed with high contrast – such as a black code printed on a white background – seeing or imaging the code is easy. But when codes are permanently marked on parts using Direct Part Mark (DPM) methods such as dot peen, laser, or electro-chemical etching, the codes are much more difficult to read. DPM codes often require special lighting to get a good image and extract the data out of the code. Historically, DPM-code illumination has been a challenge that required testing different lighting techniques. Once it was determined whether bright-field, dark field or diffuse-on-axis  lighting gave the best results, the proper lighting components would have to be purchased and installed. While this process is not too difficult for a single application, many factories and distribution centers have many different DPM applications and testing and deploying the optimal lighting solution for each one would be a very time-consuming and expensive process. Cognex®  UltraLight® illumination technology solves this problem by combining bright-field, dark field and dome illumination in a single device that can read virtually any code on any part or surface.  Bright-field lighting projects at 90 degrees to the marked surface and then reflects back up to the image to handle high-contrast labels and marks. Dark field lighting projects light at angles of 30 degrees to the marked surface which then reflects back up to the imager. This effect increases the contrast of dot peen or laser marks that are difficult to see in bright-field lighting. Dome lighting, also known as cloudy-day or diffused-off-axis illumination, projects light from many different directions to negate reflections and shadows. This technique provides even lighting across curved reflective surfaces to simulate flat objects. It is easy to take advantage of the power of UltraLight. Out of the box, the DataMan 8600 comes with 4 preset defaults enabled and the device can read a wide variety of codes. Additionally, you can enable extended read attempts mode though the auxiliary button and this enables 4 additional read setups. Of course, you can adjust UltraLight settings manually as well by turning on and off lighting quadrants and adjusting the light intensity. The end result is that you will be able to read a wide range of marked surfaces – dot peen, laser etched, ink jet, on glass, smooth or rough metal and shiny surfaces – without having to determine your lighting needs up front. • Download the Cognex Barcode Reader Product Guide • Get Product Pricing • Contact your local Cognex sale representative

More and more 1-D and 2-D barcodes are used during the manufacturing process and throughout the supply chain to identify and track specific components, sub-assemblies or products. The process of tracking items through manufacturing and distribution is known as traceability. The majority of these codes are read automatically by fixed-mount barcode readers. However, many applications require the flexibility of handheld barcode readers. These applications require extensive mobility to ensure codes can be read wherever they may be located. The result is that large numbers of handheld ID readers are being deployed in factories and distribution centers around the world. As the numbers of handheld readers in factory automation have increased, integrators are faced with the challenge of connecting readers with a wide range of local and enterprise-level computing systems. Conventional handheld barcode readers provide little or no communication capabilities with networks or factory automation equipment, such as PLC’s. This shortfall limits the areas where handheld readers can be used and increases the integration complexity. Cognex® is addressing this challenge with the DataMan® 8000 series, the first handheld readers to offer industrial Ethernet communications. DataMan 8000 series readers can be integrated directly into the factory network for real-time traceability with the Cognex Connect suite of industry protocols. Cognex Connect provides a seamless and reliable link between DataMan 8000 series handheld readers and virtually all factory automation and computing systems, making it possible to transmit results and communicate directly with an integrated process control system. The following lists some of the protocols supported by the new DataMan 8600 handheld readers: • TCP/IP • EtherNet/IP with Rockwell® Add On Profile (AOP) • PROFINET with Siemens® GSD • Modbus/TCP • MCProtocol The DataMan 8000 series readers are also the first readers with interchangeable communications modules that provide RS-232/USB, Ethernet and wireless connectivity. This flexibility makes it possible to easily modify a handheld reader to meet future requirements or move it to a different application.

There are many types of scanning applications but today I’m going to focus on the more complex scan tunnels, where labels could be on any one side or one multiple sides of a package. The challenges, complexity and costs of these systems tend to be quite high, and have been historically been solved using line scan camera technology. Read More...

No reads are a very important metric for DCs. A no read is an attempt to read a barcode on a package which results in a non-successful read. Having no reads means that a package needs to be manually handled or a package could make its way onto a truck and out for shipment without the data making it into the system. Read More...
