Invented in 1952, the D-Subminiature or D-Sub connector was designed to be a full interconnect system for input-output applications involving signal and power. The name originated from the “D” shaped metal shield and its miniature size. D-Sub connectors meet the DIN 41652 and MIL-C-24308 dimensional standards. FCI's D-Sub connectors are part of an industry standard for applications requiring robust and reliable connectors. Today, FCI is one of the major global manufacturers for D-Sub connectors offering a full range of product with a large selection of accessory options for any design requirement.
