PRODUCT LINE OF MIL-DTL-83723*, SERIES III
CONNECTORS.
MIL-DTL-83723, SERIES III CONNECTORS
WITH BAYONET COUPLING
M83723/71 & 72
wall mounting
receptacle
This series provides many choices within the range of
a medium sized, environmentally resistant circular
connector . With three coupling style choices -
bayonet, threaded and quick-disconnect - 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 .
M83723/73 & 74
jam nut
receptacle
• 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
• Intermateable with most
MIL-DTL-26500 bayonet
coupling connectors
DESIGN CHARACTERISTICS
• Recommended operating voltage to 600 VAC
(RMS) at sea level
• Complete environmental sealing includes
individual 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 diameters
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 SAE AS39029** 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 characteristics
• 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
• MS and Commercial versions available
• Alternate positioning available
• Aluminum shells with black anodized, cadmium or
electroless nickel finish options; passivated
stainless steel shells are also available

ALTERNATE KEYING POSITIONS
To avoid cross-plugging problems in
applications requiring the use of more than
one connector of the same size and
arrangement, alternate keying positions are
available as indicated in the chart below .
The diagram shows the engaging view of a
receptacle shell with keyways . Plug shells
would be the opposite of this diagram .
In the “alternate keying positions”
(positions 6, 7, 8, 9 and Y), the minor keys/
keyways are positioned with reference to
master key/keyway as indicated in the
keying position table .
