MIL-C-
83723, Series III Connectors. These connectors incorpo-
rate crimp rear release contacts. There is great diversity
within this cylindrical family, with the following options
available:
• Three coupling styles - bayonet or threaded plugs and
receptacles, and quick-disconnect plugs with or with-
out lanyards
• Aluminum or passivated stainless steel versions
• A wide variety of mounting configurations
• Can be ordered by military or equivalent Amphenol/
Matrix proprietary part numbers.
The Matrix
®
connectors covered in this catalog broaden
the miniature cylindrical family offered by Amphenol.
Equivalent MIL-C-83723, Series III connectors can be
ordered in the Amphenol
®
/Pyle
®
versions. Within the Pyle
product family of MIL-C-83723 are additional options
such as high temperature firewall versions and hermetic
styles. See page 22 for more information on the Amphe-
nol/Pyle versions of MIL-C-83723, Series III connectors.

MIL-C-83723, Series III Connectors
general description, features and benefits
Amphenol broadens their Miniature Cylindrical
Family of Connectors with the addition of the
Matrix
®
Product line of MIL-C-83723, Series III
Connectors.
This series provides many choices within the
range of a medium sized, environmentally resis-
tant cylindrical connector. With three coupling
style choices - bayonet, threaded and quick-dis-
connect - the versatility of this family makes it
increasingly popular for panel mount, box mount
and line-to-line applications in aircraft. For general
duty environmentally resistant requirements, this
family of connectors provides a wide range of
interconnection solutions.

Connector Design Characteristics
• Recommended operating voltage to 600 VAC
(RMS) at sea level
• Complete environmental sealing includes indi-
vidual contact seals and a silicone elastomer
interfacial seal with raised barriers around each
pin, a shell-to-shell seal and an insert-to-shell
seal. Sealing over a wide range of wire diame-
ters is assured by a triple-webbed grommet
design
• Captive coupling nut prevents tampering, while
a reduced coupling ring ramp allows easier
mating
• Incorporates crimp rear release contacts in
sizes 12, 16 and 20; contact arrangements
accept 2 to 61 circuits
• Contacts conform to MIL-C-39029 and use
standard qualified rear-release type plastic
tools
• Insertion and removal of contacts from the rear
of the connector assures no damage to the
front that might affect the sealing characteris-
tics
• Grommets are constructed of tear-resistant
elastomer and experience no degradation
when exposed to a broad range of fluids
• Closed entry socket side of the insert is
designed with a lead-in chamfer and a hard
face that will accept a pin contact bent within
pre-established limits
BAYONET COUPLING CONNECTORS
• Quick positive coupling assured by 3 point bayonet coupling
system; visual confirmation of complete coupling
• Five key/keyway design eliminates mismating
• Shell sizes 8 – 24 in the following mounting styles:
• wall mounting receptacle
• jam nut receptacle
• straight plug, straight plug with RFI grounding (provides
EMI shielding)
• MS and Proprietary versions available
• Alternate positioning available
• Intermateable with most MIL-C-26500 bayonet coupling
connectors
• Aluminum shells with black anodized, cadmium or electroless
nickel finish options; also shells of passivated stainless steel are
available.
THREADED COUPLING CONNECTORS
• Threaded coupling offers greater resistance to decoupling with
a visual full mating indicator band on the shell
• Shell sizes 8 – 28 in the following mounting styles:
• wall mounting receptacle
• jam nut receptacle
• straight plug, straight plug with RFI grounding (provides EMI
shielding), and straight plug with a self-locking clutch plate
• MS and Proprietary versions available
• Alternate positioning available
• Intermateable with most MIL-C-26500 threaded coupling
connectors
• Aluminum shells with black anodized, cadmium or electroless
nickel finish options; also shells of passivated stainless steel are
available.
QUICK-DISCONNECT COUPLING CONNECTORS
• Push-pull, quick-disconnect coupling is available in a straight
plug, that can be ordered with or without a lanyard release
mechanism
