MIL-DTL-83723 Series III
Features and Application
Bayonet and Threaded Coupling
Features and Application
MIL-DTL-83723 Series III family oers connectors with
bayonet and threaded coupling including lanyard-release
quick-disconnects. ese connectors combine the best features
of MIL-DTL-26500 and NAS 1599 miniature connector
specications. ey are intermateable with both bayonet and
threaded 26500 connectors (exception: shell size 8, threaded
coupling only) and have the added advantage provided by the
rear-release contact retention system.
AE833 connectors are widely used on commercial, military
and aerospace systems requiring general-purpose, miniature
cylindrical bayonet or threaded coupling connectors. In
addition, Series III threaded connectors with self-locking
plugs are well suited for engine applications.
is family of connectors (bayonet as well as threaded) is
oered in wall mount receptacles as well as jam nut mounted
receptacles which incorporate “O” ring seals, designed for
rear panel “D” hole mounting.
Series III bayonet-coupling plugs are available in two designs
- with and without RFI grounding. readed coupling plugs
are oered with and without RFI grounding, self-locking
and RFI/self-locking. In addition we oer quick-disconnect
(lanyard release) plugs, which mate with threaded receptacles
via an adapter.
irty-one insert arrangements per MIL-STD-1554 are tooled
and qualied to MIL-DTL-83723 Series III, utilizing
2 to 61 M39029 contacts. Contacts come in sizes 20, 16 and
12, terminating wire sizes from 24 to 12 gauge.
ese connectors are available in wide range of shell materials
and nishes. Aluminum shells are oered in electroless nickel,
olive drab cadmium and black anodic. Other nishes such as
zinc cobalt are available upon request to commercial callouts
only. In addition, we oer passivated stainless steel shells
with both standard and rewall-rated inserts, and for highly
corrosive environments, nickel-aluminum-bronze shells
with standard environment-resisting inserts (commercial
callouts only).
Universal I/R Tool – A single, expendable plastic tool is used
for both insertion and removal of contacts.
Shell Polarization – Alternate key/keyway positions pre-
vent cross mating of adjacent connectors having same insert
arrangement.
Closed-Entry Socket Insert – Hard dielectric socket face has
lead-in chamfers for positive alignment of pins (even partially
bent within pre-established limits) with sockets.
Interfacial Pin Insert Seal – Raised moisture barriers around
each pin, which mate into lead-in chamfers of hard face sock-
et insert, provide individual contact sealing. Interfacial seal is
never touched by service tools.
Elastomer Wire Sealing Grommet – Sealing over a wide
range of wire diameters is assured by a triple wire seal in each
cavity at the rear of the connector.
Superior Contact Stability – Rear release crimp contact
system features a stamped beryllium-copper retaining clip
captivated by molded-in shoulders of each contact cavity in
the insulator. A rear-inserted M81969 plastic tool expands the
tines beyond the shoulder, releasing the contact.

Corrosion Resistance
Class W withstands 500-hour salt spray.
Class R withstands 48-hour salt spray.
Environmental Seal
Wired, mated connectors with specied accessories at-
tached, shall meet the altitude-immersion test specied by
MIL-DTL-83723 Series III.
Fluid Resistance
Connectors resist specied immersions in MIL-PRF-7808
(lubricating oil), MIL-PRF-23699 (lubricating oil),
MIL-PRF-5606 (hydraulic uid), M2-V Chevron oil, Coola-
nol 25, MIL-DTL-83133 (turbine fuel JP-8),
MIL-DTL-5624 (turbine fuels JP-4 and JP-5), SAE-AMS1424
Type I (defrosting uid), and other solvents and cleaning
agents.
Voltage Rating
Durability
Mated connectors withstand a minimum of 500 mating
cycles for bayonet coupling straight plug (M83723/75,
76); 250 mating cycles for bayonet coupling RFI plug
(M83723/77, 78); and 250 cycles for all threaded coupling
plugs (M83723/86, 87, 91, 92, 95, 96, 97, 98).
Shock and Vibration Requirements
Wired, mated connectors shall not be damaged, coupling
ring shall not loosen, and there shall be no interruption of
electrical continuity longer than one microsecond when
subjected to the following:
Shock
Mated connectors withstand a pulse of approximate half
sine wave of 300 G ± 15 percent magnitude with duration of
3 ± 1 milliseconds applied in three axes.
Vibration
Mated connectors withstand the following vibration levels:
Random vibration per MIL-STD-1344, method 2005, test
condition VI, letter J.
Shielding Eectiveness
RFI attenuation at the specied frequency meets the require-
ments of MIL-DTL-83723 Series III.
RFI shielding eectiveness of mated connectors with
RFI backshells is measured in a triaxial radio frequency
leakage xture.
Shell-to-Shell Conductivity (Except class A)
With RFI spring ngers, the maximum potential drop
shall not exceed 5 millivolts.
Without spring ngers, the maximum potential drop
shall not exceed 200 millivolts.
