History of DIN 41612

DIN 41 612 was conceived as a two piece connector system for 19’’ modular sub-racks and was widely adopted in telecom applications (backplane to daughter card).The standard was introduced in 1976 (evolved from an earlier German military VG standard) and was subsequently updated to IEC 60603-2, which describes electrical connectors that have two or three rows of contacts with 16 or 32 columns per row, with contact spacing of 0.1” (2.54mm).

These connectors have a variety of pin counts depending on body type with a maximum of 96 contacts in 3 rows, and form the basis for a much wider range of complementary products which are not covered by the standard.

In 1996 the new IEC 61 076-4-113 standard was written, for VME 64x architecture. The HARTING har-bus 64 range of connectors was developed, offering connectors with 160 pins, while still maintaining full backward compatibility with traditional 96 pin DIN 41 612 connectors. VME 64x offers additional functionality beyond the traditional VME standard, further extending the life of the DIN 41 612 family of products.
