Blog: The 2D Data Matrix Code in Electrochemical Marking (Electromarking)

Here at IMG-Electromark, there has been a significant increase in our customers’ demand to apply Data Matrix codes marked onto their metal parts, especially those companies working to MIL-STD-130 (which is the standard approved by all departments and agencies of the Department of Defense).

So, what is the 2D Data Matrix Code?

A Data Matrix is a two dimensional bar code, usually square in shape. Imbedded into its black and white modules or cells is either encoded text or raw data. A Data Matrix symbol can store up to 2,335 alphanumeric characters. It is a dependable, economical means for identifying and tracking products through the manufacturing cycle.

Among the many advantages of the Data Matrix over the common 1D barcode is that it offers high information density and it can be applied directly onto metal parts, known as direct part marking. This code allows the implementation of Machine Readability Information (MRI) and Human Readability Information (HRI) for item identification marking and automatic data capture. The machine readable format is what makes this mark so useful for the DoD.

The Data Matrix is being used when traditional bar codes are too large, don’t provide enough storage capacity, or are unreadable. Plus a Data Matrix can be read even if up to 20% of the code is damaged or unreadable. Data Matrix is especially effective for the labeling of metal parts and it’s widely used in the aerospace, electronic, and automotive industries, this list is sure to grow as time goes on.

Our expert staff has been trained to write codes for the DoD (there is a specific language required), apply the codes electrochemically (as well as by laser) and then verify them. Should you have any questions on this or other marking requirements, please call us at 1.800.775.3824 or email and we will do our best to help. Thank you.

Until next time,
