These connectors are intended for general military use. Connector installations should be designed to assure that connectors are mated within the limits prescribed in 3.4.5. The class and types of connectors are intended for application as follows:

a. Classes G and N connectors are intended for use in nonenvironment-resisting applications where the operating temperature range of −55° to +125°C is experienced. Crimp contact connectors have the additional advantage of possessing removable crimp-type contacts.

b. Class N connectors are intended for use in applications wherein presence of residual magnetism must be held to very low levels to avoid interference with nearby sensitive instrumentation.

c. Class H receptacles are intended for use in applications wherein atmospheric pressures must be contained by the connectors across the wall or panels on which they are mounted. If air leakage requirements are critical, a class H connector should be used.

d. Crimp contact connectors shall have contacts present in all positions when the connector is installed.

e. Classes D, K, and M connectors are for high reliability space applications.

f. Connector installations should be designed to assure that connectors are mated within the limits prescribed in 3.4.5.
