scope:

This specification covers the general requirements and tests for radio frequency connectors used with flexible RF cables and certain other types of coaxial transmission lines.

The categories of connectors are designated by an A (field serviceable), B (non-field replaceable, special tools may be required), C (field replaceable, solder center contact), D (field replaceable, crimp center contact), E (field replaceable), F (field replaceable) and M (field replaceable) as follows:

a. Category A - Connectors which do not require special tools to assemble are designated as category A connectors. Standard wrenches, soldering equipment, pliers, etc., are not defined as special tools. Intended for use on flexible cables only.

b. Category B - Connectors which require special tools to assemble are designated category B connectors. These connectors are for original equipment manufacturers use only. A qualified source for the replacement connector in another category must be in existence before connectors from this category can be used by the OEM. Loss of the qualified source for the replacement connector will force the removal of the associated category B part from the QPL as well. Category B connectors will not be stocked or procured by the Government.

c. Category C - Connectors which require only standard military crimping tools for braid attachment and standard cable stripping dimensions to assemble are designated as category C connectors. The standard military crimping tool is as specified in 3.1. Center contacts are assembled by solder. Intended for use on flexible cables only.

d. Category D - Connectors which require only standard military crimp tools for the center contact and outer ferrule, and standard cable stripping dimensions to assemble are designated as category D connectors. The standard military crimp tools are as specified in 3.1. Intended for use on flexible cables only.

e. Category E - Connectors using semirigid cables with standard stripping dimensions and using standard soldering tools.

f. Category F - Connectors using semirigid cables with standard stripping dimensions and using standard military tools. The method of assembly of the connector to the cable is crimping for at least the outer conductor. Center contacts may be soldered.

g. Category M - Connectors using semirigid cables with standard stripping dimensions using standard military tools. The method of assembly is mechanical and does not require the use of crimping tools or soldering irons.

intended Use:

Connectors and fittings covered by this specification are intended for use in radio frequency applications up to the frequency specified (see 3.1).
