DIN connector

A DIN connector is an electrical connector that was originally standardized by the (DIN), the German national standards organization. There are DIN standards for a large number of different connectors, therefore the term "DIN connector" alone does not unambiguously identify any particular type of connector unless the document number of the relevant DIN standard is added (e.g., "DIN 41524 connector"). Some DIN connector standards are:

• DIN 41524, for circular connectors often used for audio signals
• DIN 41612, rectangular connectors used to connect plug-in cards to a back plane or motherboard
• DIN 41652 D-subminiature connectors used for computer data and video

In the context of consumer electronics, the term "DIN connector" commonly refers to a member of a family of circular connectors that were initially standardized by DIN for analog audio signals. Some of these connectors have also been used in analog video applications, for power connections and for digital interfaces such as MIDI or the IBM AT computer keyboard (later PS/2 connectors for keyboard and mouse are Mini-DIN connectors). The original DIN standards for these connectors are no longer in print and have been replaced with the equivalent international standard IEC 60130-9.
