As outlined above, the term Eurocard defines a standardised size and format of printed circuit boards (PCBs) that can be plugged into an (also standardised) chassis or rack mount. This allows for a great deal of flexibility and interchangeability across multiple equipment setups and mounting arrangements.
As a result, a wide variety of industrial machinery, panels and equipment nodes stand to benefit from the increased cost-effectiveness of a single universal mounting solution for common PCB sizes and layouts, without having to invest in costly sector or application-specific hardware mounting solutions on a case-by-case basis.
A standard Eurocard PCB thus plugs into any appropriate subrack, chassis or PCB enclosure, and these rack mounts will generally comprise a number of slotted card guides on the top and bottom of its interior panels.
