This catalog covers the Amphenol ®/Matrix ® 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.

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.
Amphenol®/Matrix® MIL-C-83723, Series III
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

alternate positioning
ALTERNATE KEYING POSITIONS
(Rotation of key/keyway of shell)
To avoid cross-plugging problems in applications requiring the
use of more than one connector of the same size and arrange-
ment, alternate keying positions are available as indicated in
the chart below.
The diag ram sh ows the eng aging v iew of a recept acle s hell w ith
keyways . The ins ert is rot ated co unter-c lockwi se relati ve to the
centerline. Plug shells would be the opposite of this diagram.
In the “Normal insert position” (position N), the insert center line
coincides with the centerline of the master key/keyway of the
shell.
In the “alternate keying positions” (positions 6, 7, 8, 9 and Y),
the minor keys/lkeyways are positioned with reference to mas-
ter key/keyway as indicated in the keying position table.
* Position Y supersedes inactive positions 10 and Z designations.

ALTERNATE CLOCKING POSITIONS
(Rotation of insert)
Alternate positioning is also available with the rotation of the
insert. The diagram below shows the pin insert mating face.
The centerline of the shell in the normal insert position (position
N) coin cides with the cente r lin e of th e m as ter ke y/ key w ay in th e
shell.
In alternate clocking positions, (positions 1, 2, 3, 4 and 5), the
insert rotates relative to the centerline of the key/keyway of the
shell. See E° callout on diagram and the table for insert clock-
ing. The socket insert is rotated clockwise, and the pin insert is
rotated counter-clockwise.
Note: Positions 1-5 are inactive for new designs per MIL-STD-1554.
