Type plates are attached to devices by the manufacturer to clearly identify them. In some cases this is even required by law.
Type plates contain information such as manufacturer, type name, serial number, performance data, etc. This information must be legible for a very long time, even under extreme conditions such as wetness, high or low temperatures and in oily environments.
Serial number labels are characterized by particularly good durability. They are printed with a consecutive number, pictograms, barcodes and text.
