TABLE I. Dash number and applicable cable Continued.
* Not for Naval Air Systems Command (AS) use.
1/ The "X" is placed in the dash number to allow the user connector body
plating options provided in the general specification. Only connectors of
the same materials are to be intermated to reduce the possibility of dissimilar
problems, including galvanic corrosion.
2/ The latest version of each cable shall be applicable.
3/ These connectors have captivated center contacts.
4/ These parts are no longer restricted from Navy use.
5/ Preferred keying arrangement.
6/ Inactive for new design (see table III).
7/ Cables to be used for the +200°C thermal shock test.
8/ These connectors are assembled using the applicable crimping tool to the
specified cables.
9/ Complete connector assembly shall consist of a body, center contact,
intermediate contact, ferrule, and assembly instructions.
