Know About Direct Part Marking Barcode Scanners

The concept of tracking products using barcodes has already proved to be a great technique that provides positive results. It is a well-known fact that various industries such as retail, warehousing, education, manufacturing, healthcare and others use barcode technology to enhance their business processes. The only places that hinder barcode label usage on products are harsh environments where temperatures are high and extreme solvents and chemicals are used.

In order to track products throughout their life cycle and to improve the performance of automatic tracking systems, many businesses today are using the Direct Part Marking (DPM) method. It involves engraving permanent barcodes directly on the products by various methods. Here are some features of direct part marking barcode scanners that are designed to read such barcodes.

Features of DPM barcode scanners
Direct part marks are 2D or 3D barcodes marked on substrates such as metal, plastic, rubber or glass. Different methods such as dot peen, laser or chemical etching, molding, and casting are used for marking them. There is low contrast between the symbol and the product surface, so it is challenging for regular barcode scanners to read them. DPM barcode scanners have special features that allow them to efficiently read those marks. They read the barcodes by determining the height of lines.

Image-based barcode reading
The most important feature of DPM barcode scanners is advanced digital imaging technology. DPM scanners use special lighting techniques to read the low-contrast barcodes. They provide a uniform illumination on the barcode through specific low-angle lighting and quadrant control features.

A DPM barcode scanner contains a high resolution image sensor that captures the image of the barcode. It can capture low and high contrast marks on any surface including reflective, irregular and curved ones. They have the ability to read even wrinkled marks on the products.

More durable
Direct part marking identification requires rugged and self-contained scanners that can read codes on a wide range of surfaces. As they are image-based scanners, they do not have any moving parts. They are less likely to fail because of damage and are shock-resistant. They are designed in such a way that they can withstand harsh environments. So DPM scanners are more durable and preferred mostly for manufacturing and warehouse applications.

Reads all types of codes
DPM barcode scanners are generally used for reading engraved 2D and 3D barcodes. However, they can also read linear barcodes printed on different types of barcode labels. You can therefore choose DPM barcode scanners when you deal with DPM as well as linear barcode applications in your business. This helps you to eliminate the need to purchase, maintain and support multiple devices for reading barcodes of various symbologies.

Easy to use
DPM barcode scanners are available in corded and cordless versions. They possess omni-directional functionality and can read marks on products aligned at any angle or direction. Hence, they are easy to use and reduce your time and effort in aligning the barcode properly. You do not need any specific training to handle them. Thus, DPM scanners help you to save your money and time that in turn improves productivity and throughput.

As discussed above, DPM barcodes are developed to avoid damage to barcodes due to high temperatures and chemical solvents. With advanced features like image-based scanning and high durability, DPM scanners are the most suitable for manufacturing, warehousing or other industries where environments are harsh.
