Reading of Direct Part Marking Codes with Handheld Reader OHV1000

The application

OHV1000 Handheld Reader – the expert for reading of Direct Part Marking (DPM) codes
OHV1000 Handheld Reader – the expert for reading of Direct Part Marking (DPM) codes

An effective way to identify products in production and logistics areas is to mark them directly with two-dimensional codes, such as Data Matrix codes. These codes, which are applied to the product or workpiece with direct part marking (DPM), allow you to identify individual production steps and data at any time. It is then possible to track the entire service life of a product.

DPM codes are primarily used in mechanical engineering applications and in the electronics and automotive industries. The codes are placed on printed circuit boards, as well as metal and plastic components. Laser etching, dot peen marking, and ink jet marking are among the most common methods of attaching codes directly to parts.

The goal

The goal is to reliably read a wide range of code symbologies in addition to DPM codes. These include long 1-D barcodes, which are often used on job order cards in the automotive industry.  All reading results must be automatically mapped within an ERP system. This system is then used to further process data.

The solution

With its patented dual lens and high resolution of 1.2 megapixels, the OHV1000 handheld reader allows the simultaneous reading of small, complex DPM codes with a module size of up to 0.1 mm, and longer, printed 1-D and 2-D barcodes. Because you do not need to change the settings every time you encounter a different type of code, the reader is very flexible and efficient. This makes the OHV1000 a perfect solution when dealing with a variety of code symbologies.

The intuitive "Vision Configurator" parameterization software automatically writes the read results into the correct fields in the ERP system without the need for any time-consuming programming work.

The benefits

The OHV1000 handheld reader is ideal for a large number of applications and ensures reliable reading performance. It is highly customizable to individual applications and can be easily integrated into ERP systems.
