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. DIN 41612 connectors are used in STEbus,〔 Michael J. Spinks. ("Microprocessor System Design: A Practical Introduction" ). 2013. p. 158. 〕 Futurebus, VMEbus, Multibus II, NuBus, VXI Bus,〔 ("Eurocard Connectors per DIN 41612 and IEC 60603-2" ) 〕 eurocard TRAM motherboards,〔 ("IMS B012 User Guide and Reference Manual" ). ("Appendix A" ). 1988. 〕 and Europe Card Bus, all of which typically use male DIN 41612 connectors on Eurocards plugged into female DIN 41612 on the backplane in a 19-inch rack chassis. ==Mechanical details== The standard describes connectors which may have one, two or three rows of contacts, which are labelled as rows a, b and c. Two row connectors may use rows a+b or rows a+c. The connectors may have 16 or 32 columns, which means that the possible permutations allow 16, 32, 48, 64 or 96 contacts. The rows and columns are on a 0.1 inch (2.54 mm) grid pitch. Insertion and removal force are controlled, and three durability grades are available. Often the female DIN 41612 connectors have press fit contacts rather than solder pin contacts, to avoid thermal shock to the backplane.〔 Andrew Fletcher.
