DIN connector
The DIN connector is an electrical signal connector that was standardized by the Deutsches Institut für Normung (DIN), the German Institute for Standards, in the mid 1950s, initially with three pins for mono, but when stereo connections and gear appeared in the late 1950s, versions with five pins or more were made. The male DIN connectors (plugs) feature a 13.2 mm diameter metal shield with a notch that sets the orientation in which plug and socket can mate. The range of DIN connectors, different only in the configuration of the pins, has been standardized as DIN 41524 / IEC/DIN EN 60130-9 (3-pin at 90° and 5-pin at 45°); DIN 45322 (5-pin and 6-pin at 60°); DIN 45329 / IEC/DIN EN 60130–9 (7-pin at 45°); and DIN 45326 / IEC/DIN EN 60130-9 (8-pin at 45°).
In consumer electronics, the cylindrical connectors were adopted for analog audio signals. Some DIN connectors have been used in analog video applications, for power connections, and for digital interfaces, such as the MIDI (DIN 41524), the IBM PC keyboard and the IBM AT keyboard connectors (DIN 41524). The original, technical standards for these models of DIN connector are unavailable, and were replaced with equivalent connectors, such as the international standard IEC 60130-9.
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 45322 connector"). Some DIN connector standards are:
The plugs consist of a circular shielding metal skirt protecting a number of straight round pins. The pins are 1.45 mm in diameter and equally spaced (at 90°, 72°, 60° or 45° angles) in a 7.0 mm diameter circle. The skirt is keyed to ensure that the plug is inserted with the correct orientation, and to prevent damage to the pins. The basic design also ensures that the shielding is connected between socket and plug prior to any signal path connection being made.
There are seven common patterns, with any number of pins from three to eight. Three different five-pin connectors exist, known as 180°, 240°, and domino/360°/270° after the angle of the arc swept between the first and last pin. There are also two variations of the six-pin,[citation needed] seven-pin (one where the outer pins form 300° or 360° and one where they form 270°), and eight-pin (one where the outer pins form 270° and one where they form 262°) connectors.
There is some limited compatibility; for example, a three-pin connector will fit any 180° five-pin socket, engaging three of the pins and leaving the other two unconnected; and a three-pin or 180° five-pin connector will also fit a 270° seven-pin or either eight-pin socket.
In addition to these connectors, there are also connectors with 10, 12, and 14 pins. Some high-specification equipment used seven-pin connectors where the outer two carried digital system data; if the connected equipment was incompatible, the outer two pins could be unscrewed from the plugs so that they fitted into standard five-pin 180° sockets without data connections.
As the keying is consistent across all connectors, it does not completely prevent incompatible connectors from mating, which can lead to damage; this is changed in Mini-DIN, which keys different connectors.
