4.3 General Notes About the Barcode

In this day and age, increasing numbers of components, individual components, semi-finished and end

products are being uniquely identified with a barcode, which makes them easier to check. This, in turn,

makes it easier to control production, stock-keep and to trace components in the event of errors. Both

one-dimensional (1D, e.g. barcodes) and two-dimensional (2D, e.g. data matrix codes) codes can be

used.

4.3.1 Structure of 1D Barcodes

Barcode types include 2/5 interleaved, Codabar, Code 39, Code 128, EAN 8, EAN 13 for industrial ap-

plications.

The 1D barcode scanner reads the barcode using a red light laser diode and a rotating mirror wheel,

which creates a red scanning line that is visible to the human eye.

The structure of a barcode, the number of black lines and white gaps for each character to be coded is

fixed for each barcode type. The information is located in both the lines and the gaps of a barcode. But,

in general, the following structure can be defined for a barcode.

Structure of a 1D barcode

Advantages:

▪ Up to 50 characters can be encoded, depending on the type of code.

▪ Barcodes can be read and scanned very reliably with the optical scanning system.

▪ Barcodes are cheap to produce.

▪ Barcode scanners are very cheap to buy.

Disadvantages:

▪ The print quality of a barcode on the labels is a decisive factor in the scanning result.

NOTICE

Barcode changeover

Before you use a new barcode, we recommend that you contact your SIPLACE Service team

and have the barcode tested in advance.
