1.1 Scope
This specification covers miniature, composite, high density, threaded coupling, self-locking, circular, environment
resistant, electrical connectors utilizing removable crimp contacts, and associated hardware, which are capable of
continuous operation within a temperature range of -65 to +175 °C. These connectors are supplied under an AS9100
reliability assurance program. See 6.1 for intended use and applications.
1.2 Description
The connectors employ rear release removable pin and socket contacts with crimp termination. The connectors are
designed to assure proper orientation of the mating halves prior to electrical circuit closure. The connectors include EMI
shielding capability. They also provide electrical continuity between mated shells prior to contact engagement and have
the contacts so located as to be protected from handling damage and inadvertent electrical contact. The connectors
consist of a composite material with light weight characteristics and, when used with backshells and contacts specified
herein, provide high levels of corrosion resistance and durability.
1.2.1 Design Considerations
Connectors are designed to be used as a system with backshells and contacts specified herein. When so used, the
connectors are capable of performance during or after, as applicable, under the following environmental conditions:
1.2.1.1 Temperature
-65 to +175 °C.
1.2.1.2 Vibration
a. Random: 41.7 G rms at rated high and low temperatures without backshell.
49.5 G rms at ambient temperature with backshell.
b. Sine: 60 G at ambient temperature with backshell.
1.2.1.3 Altitude
Altitudes from sea level to 100 000 ft (8 torr). Test voltage will vary with altitude (see Table 12).
1.2.1.4 Shock
Shock as represented by a 3 + 1 ms base half-sine wave peaking at 300 G (see 3.23).
1.2.1.4.1 High Impact Shock
Per MIL-S-901.
1.2.1.5 Humidity
Humidity conditions up to 98 percent relative humidity including condensation (see 3.25).
1.2.1.6 Corrosion
2000 h exposure to salt-laden atmosphere (see 3.15).
1.2.1.7 Temperature Cycling
See 4.6.3.
1.2.1.8 Fluid Immersion
Immersion, in jet fuel, lubrication oil, liquid coolant, hydraulic fluid, gasoline, cleaning compound, defrosting fluid, and
solvents (see 3.29).
1.2.1.9 EMI Shielding
EMI shielding effectiveness: 100 MHz to 10 GHz, minimum attenuation of 50 dB (see 3.27).
1.2.1.10 Electrolytic Erosion
Exposure of uncoupled connector to a salt moisture environment (see 3.34).
1.2.1.11 Durability
1500 matings and unmatings (see 3.4.1 and 3.10).
1.3 Classification
1.3.1 Connectors
Connectors fabricated to this specification are scoop-proof, self-locking, quick coupling and are as follows:
a. Series: The series A and B connectors are not intermateable.
A - Utilize MIL-DTL-38999 insert arrangements.
B - Utilize MIL-C-81511 insert arrangements.
b. Types:
(1) Plugs: Straight.
(2) Receptacles: Wall mounting, both front and rear panel mounting, jam nut mounting. Contains grounding member
that makes shell contact prior to contact engagement.
c. Class: R - Environment resisting - conductive shell, EMI shielded.
E - Environment resisting - conductive or nonconductive shell, non-EMI shielded.
G - Environment resisting - conductive shell, EMI shielded, space grade.
1.3.2 Contacts
a. Styles:
(1) Connectors ordered with high performance contacts:
H - Pin
J - Socket
The H or J designators are used to indicate a full complement of applicable high performance contacts rated at
1500 cycles of durability, and shall appear in the part number marked on the connector.
(2) Connectors ordered with standard contacts:
P - Pin
S - Socket
The P or S designators are used to indicate a full complement of applicable standard contacts rated at 500 cycles
of durability, and shall appear in the part number marked on the connector.
(3) Connectors ordered without contacts:
A - Less pin contacts. Application specifies 500 cycles of durability.
B - Less socket contacts.
K - Less pin contacts. Application specifies 1500 cycles of durability.
L - Less socket contacts.
The A, B, K, or L designators are used to indicate connectors ordered less contacts, and are intended to have
other than all standard power contacts installed (example: shielded, coaxial and thermocouple contacts). The A,
B, K, or L designator shall appear in the part number marked on the connector.
Connectors ordered less contacts, but intended for assembly with all high performance or all standard contacts, shall have
the H or J designator, or the P or S designator, respectively in the part number marked on the connector the same as
connectors ordered with a full complement of applicable contacts.
1.3.3 Associated Hardware
a. Types:
(1) Backshells.
(2) Protective covers.
(3) Dummy stowage receptacles.
(4) Sealing plugs.strRefField
