DIN 41612 is a
DIN standard for electrical connectors that are widely used in rack based electrical systems. Standardisation of the connectors is a pre-requisite for open systems, where users expect components from different suppliers to operate together. The most widely known use of DIN 41612 connectors is in the
VMEbus system. They were also used by
NuBus. The standard has subsequently been upgraded to international standards
IEC 60603-2 and
EN 60603-2.
