The classes and types of connectors are intended for military application as follows (see 1.1.2.2):

a. Class E connector is intended for use in environmental applications where the operating temperature range of −65 to 150°C is experienced. Class F and W are intended for use in environmental applications where the operating temperature range of −65 to 175°C is experienced and additional fluid resistance is needed. Class A is intended for use in environ- mental applications where the operating temperature range of −65 to 200°C is experienced and additional fluid resistance is needed. Classes A and F are not for shipboard, jacketed cable and Naval aircraft applications, but for use in outer space.

b. All connectors are environment resisting with provisions to ensure electrical continuity from plug to receptacle shell.

c. Classes D and H receptacles are intended for use in applica- tions wherein fluid pressures must be contained by the connectors with a very low leakage rate across the walls or panels on which they are mounted.

d. Class W connectors are intended for use in environmental applications where corrosion protection is a concern.

e. To provide adequate moisture seal, wire diameters larger than minimum specified in table V-A and table V-B for the applicable contact size must be used.

f. Where two or more wires are used in a wire barrel, moisture sealing is not obtainable.

g. Crimp contact connectors shall have contacts installed in all positions when the connector is wired. Sealing plugs shall be installed in the grommet holes when no wire is attached to the contact in grommet-sealed connectors.
