MIL-DTL-26482
Features and Application
Series 2
Features and Application
MIL-DTL-26482 Series 2, bayonet coupling, rear-removable
crimp contact connectors were designed as an upgrade to
MIL-DTL-26482 Series 1. Series 2 connectors are intermount-
able and interchangeable with both solder and front-release
crimp Series 1. ey are also identical to the inactivated
MIL-DTL- 83723 Series I connectors.
Series 2 connectors are widely used on commercial, military
and aerospace systems requiring general-purpose, miniature
cylindrical bayonet coupling connectors.
is family of connectors is oered in 4 receptacle-mounting
styles. ey include narrow ange wall mounting receptacles,
wide ange wall mounting receptacles, cable connecting recep-
tacles and jam nut mounting receptacles which incorporate “O”
ring seals, designed for rear panel “D” hole mounting.
Plugs are available in two designs, with and without RFI
grounding.
irty-three insert arrangements per MIL-STD-1669 are
tooled and qualied to MIL-DTL-26482 Series 2, utilizing
3 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 passivat-
ed stainless steel shells with standard environment-resisting
inserts (commercial callouts only), 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.
Insert Polarization – Alternate insert clocking positions
aid in mating of adjacent connectors having identical 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 socket insert, provide individual contact sealing. Inter-
facial 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.

Series 2
Performance Specications
Operating Temperature Range
Classes A, L and S*: -55°C to +200°C (-67°F to +392°F)
Classes W and ZC*: -55°C to +175°C (-67°F to +347°F)
Material and Finish Data (Class)
A – aluminum shell, black anodized nish
L – aluminum shell, electroless nickel nish
W – aluminum shell, olive drab cadmium over nickel base
S* – stainless steel shell, passivated
BN* – aluminum shell, black nickel nish (Aero P/N only)
Corrosion Resistance
Classes A, S*, W and BN* withstand 500-hour salt spray.
Class L withstands 48-hour salt spray.
Environmental Seal
Wired, mated connectors with specied accessories at-
tached, shall meet the altitude-immersion test specied in
MIL-DTL-26482 Series 2.
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, Cool-
anol 25, ASTM D4814 (gasoline), SAE-AMS1424 Type I
(defrosting uid), MIL-DTL-5624 (JP-5), and solvents
specied in Method 215 of MIL-STD-202.
* Not on QPL, can be supplied to Aero-Electric P/N only.
Durability
Mated connectors withstand a minimum of 250 mating
cycles for RFI plug (MS3475) and 500 cycles for standard
plug (MS3476).
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 magnitude with duration of three
milliseconds applied in each direction of the three major axes.
Vibration
Mated connectors withstand the following vibration levels:
• Random vibration per MIL-STD-202, method 214, test
condition II, letter J.
Shielding Eectiveness
RFI attenuation at the specied frequency meets the require-
ments of MIL-DTL-26482 Series 2.
• RFI shielding eectiveness of mated connectors with
RFI backshells is measured in a triaxial radio frequency
leakage xture.
Shell-to-Shell Conductivity
• 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.

Part Number Development
Series 2
Military and Aero-Electric Part Number Development
*Not on QPL, can be supplied to Aero part number only. Consult factory
for availability.
Note 1: Each connector is furnished with contacts unless
ordered less contacts (L/C) as follows: One spare contact for
inserts requiring 2 to 26 of each contact and two spares for
inserts with 27 or more of each size, and a minimum of one
sealing plug up to 15% of the number of contacts. In addition,
one plastic insetion/removal tool of each size is included.
Note 2: Proper part number marking has no “0” in front
of single digit shell size ( 8) and no “0” aer the dash be-
tween shell size and single digit layout. Example of each:
MS3470W8-33P and MS3470W10-6P. In both “N” for normal
was omitted.
Note 3: Insert layouts 8-2, 8-3 and 8-4 can only be ordered
to Aero-Electric part number. Non standard contacts are
required and to avoid confusion are sold “with contacts”
only. See page 80 for the correct contact part numbers.
