This specification is approved for use by all Departments
and Agencies of the Department of Defense.
The requirements for acquiring the product described herein shall consist of
this specification sheet and MIL-PRF-39012.
NOTES:
1. Dim ensions are in inches. Metric equivalents are given for information only.
2. For dimensions A and B, see tables I and III.
3. Dimensions A and B are the largest overall dimensions of the connector.
4. Wrench flats are to accommodate standard wrench opening in accordance wit h F ED-STD-H28.
5. All undimensioned pictorial representations are for reference purposes only.
6. Dimension A defines the maximum length of the connector when assembled to the appropriate
cable.
7. Three holes .027 inch (0.69 mm) minimum diameter, equally spaced, are required for safety
wiring after mating. Location on the coupling nut is optional.
8. Series N, pin contact interface, in accordance with MIL-STD-348.

TABLE II. Group qualification – Continued. 1/
1/ If a connector manufacturer produces a connector which meets all the requirements for two or more
connector PIN’s (within the same series), the manufacturer may receive qualification approval for two
or more connector PIN’s by qualifying the one connector. It is not necessary that such connectors be
in the same group. Each connector, however, must be marked with its own appropriate PIN. For
group qualification, the connectors must be of similar design and be of the same materials and
plating.
2/ For qualification retention, where more than one part is listed in a group in this column, data may be
supplied on any of those parts in order to retain qualification for those parts in the corresponding
right-hand column. The part does not necessarily have to be the part initially qualified.
