The connectors covered by this specification are intended for military use because they must be able to operate satisfactory under random vibration, 100 g's of shock, and temperatures ranging from -55 to +125 degrees Celsius. Commercial electronic components are not designed to withstand such extreme and sudden environmental conditions and would experience catastrophic failure. Connectors specified in this specification use cadmium plating and are not suitable for space applications.

Type P, plug.

Plugs are intended for use at the end of a cable mounted on panel of a unit plug-in to be mated with a panel mounted receptacle.

Type J, receptacle.

Receptacles are intended for fixed panel mounting of unit and for use with conduit to eliminate the necessity of a conduit box.

Type JS, pressurized receptacle.

Pressurized receptacles are intended for use on pressurized devices, and their performance requirements are determined by the particular application. They should maintain the degree of pressurization required by the equipment specification and be suitable for mating with plugs conforming to the requirements of this specification.

Determining wire size to be used with contact.

It is intended that the wire soldered to each connector contact should be of the AWG size (or smaller diameter) corresponding to the contact size number. For example, it is intended that an AWG size 20 wire be soldered to at least a size 20 contact.
