Design Characteristics and Options
AMPHENOL AEROSPACE OFFERS THE MATRIX®
PRODUCT LINE OF MIL-DTL-26482*,
SERIES 2 CONNECTORS
This series provides a bayonet coupling connector with crimp rear
insertable, rear releasable contacts.
MS3470
DESIGN CHARACTERISTICS
WALL MOUNTING
RECEPTACLE
WITH NARROW
FLANGE
•
•
Medium size, environmentally resistant connector
Recommended operating voltage to 1,000 VAC (RMS)
at sea level
Quick positive coupling assured by 3 point bayonet
coupling system
MS3472
•
WALL MOUNTING
RECEPTACLE
•
•
•
Visual confirmation of complete coupling
Eliminates mismating by the use of five key/keyway design
Insertion and removal of contacts from the rear of the
connector assures no damage to the front that might affect
the sealing characteristics
•
•
Utilizes same standard qualified rear-release type plastic tool
for contact insertion and removal
Contacts are qualified to SAE AS39029** requirements – BIN
coded (three color bands), and are crimped with standard
crimp tools per MIL-DTL-22520
WITH WIDE FLANGE
MS3471
CABLE CONNECTING
RECEPTACLE
•
Grommets are constructed of tear-resistant elastomer and
experience no degradation when exposed to a broad range
of fluids
Sealing over a range of wire diameters is assured by a
triple webbed grommet at the rear of the connector
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
•
•
•
Elastomer interfacial seal on the pin side has raised
barriers around each pin which displace into the socket
chamfer when mated, providing a positive moisture seal
CUSTOMER OPTIONS
MS3474
JAM NUT RECEPTACLE

narrow or a wide flange, jam nut single hole mount, and cable
connecting receptacles, along with standard plugs or plugs
with RFI grounding fingers, in shell sizes 8 to 24

sea level of 2,000 volts AC (RMS). Service Rating II is comparable to MS Service Rating D, and will provide a minimum flashover voltage
of 2,800 volts AC (RMS) at sea level.
Please note that the electrical data given is not an establishment of electrical safety factors. This is left entirely in the designer’s hands, as
he can best determine which peak voltage, switching surges, transients, etc. can be expected in a particular circuit.
OPERATING TEMPERATURE RANGE

–65°C (–85°F) to 200°C (392°F)
Pulse of an approximate half sine wave of 300g magnitude
with duration of 3 milliseconds applied in three axes.
ENVIRONMENTAL SEAL
VIBRATION:
Wired, mated connectors with the specified accessory
attached will meet the altitude immersion test specified in
MIL-DTL-26482.
Sixteen hours of random vibration having a range of 50 to
2,000 Hz with a 41.7G peak level.
DURABILITY
Minimum of 500 mating cycles.
SHOCK AND VIBRATION REQUIREMENTS
When tested as follows, the connector shall sustain no
physical damage, or electrical discontinuity exceeding
one microsecond.

STRIPPING DIMENSIONS
WIRE STRIPPING
Wire Size
A
1. Strip wire to required length. (See Figure at right). When using
hot wire stripping do not wipe melted insulation material on wire
strands; with mechanical strippers do not cut or nick strands.
2. See Table 1 for proper finished outside wire dimensions.
3. Twist strands together to form a firm bundle.

4. Insert stripped wire into contact applying slight pressure until wire insulation
butts against wire well. Check inspection hole to see that wire strands are visible. If
there are strayed wire strands, entire wire end should be re-twisted.
When wire is stripped and properly installed into contact, the next step is to crimp
the wire inside the contact by using the proper crimping tool.

CRIMPING
See table on preceding page for recommended
M22520 series crimping tools, turret head or
positioner selection settings according to
contact size, part number and wire gauge size.
** Min. diameters to ensure moisture proof assembly;
max. diameters to permit use of metal removal tools.
1. Insert stripped wire into contact crimp pot.
Wire must be visible through inspection hole.
2. Using correct crimp tool and locator, cycle
the tool once to be sure the indentors are
open, insert contact and wire into locator.
Squeeze tool handles firmly and completely to
insure a proper crimp. The tool will not release
unless the crimp indentors in the tool head
have been fully actuated.
VISUAL INSPECTION
HOLE
3. Release crimped contact and wire from
tool. Be certain the wire is visible through
inspection hole in contact.
Example M22520 Series Crimping Tool for
size 20, 16 or 12 contacts, and has a posi-
tioner that can be dialed for each contact size.
CONTACT INSERTION
1. First remove hardware from the plug
and receptacle and slide the hardware
over wires in proper sequence.
2. Use proper plastic or metal insertion
tool for corresponding contact. (Consult
tool table on preceding page). Slide correct
tool (with plastic tool use colored end) over
wire insulation and slide forward until tool
bottoms against rear contact shoulder.
3. Next align the tool and contact up to
the properly identified cavity at rear of
connector plug. Use firm, even
pressure; do not use excessive
pressure. It is recommended to start at
the center cavity. Contact must be
aligned with grommet hole and not
inserted at an angle. Push forward until
contact is felt to snap into position
within insert.
Plastic tool with contact in proper position.
Metal tool with contact.
Note: All plastic tools are double-ended.
The colored side is the insertion tool and
the white side is the removal tool.

CONTACT INSERTION, CONT.
4. Remove tool and pull back lightly on
wire, making sure contact stays
properly seated and isn’t dragged back
with the tool. Repeat operation with
remainder of contacts to be inserted,
beginning with the center cavity and
working outward in
5. After all contacts are inserted,
6. Reassemble plug or receptacle hardware
- slide forward and tighten using connector
pliers. Connector holding tools are recom-
mended while tightening back
accessories. When using strain relief,
center wires at bar clamp. Slide clamp
grommet into position and tighten clamp bar
screws. When tightening screws,
fill any empty cavities with wire
sealing plugs. (Refer to sealing
plug charts for Series III on page
18, for Series I, II, and SJT on
page 19.
alternating rows.
pressure should be applied in the same
direction that clamp is threaded to rear
threads of connector. When not using clamp
grommet, build up wire bundle
with vinyl tape so clamp bar will
maintain pressure on wires.
CAUTION when inserting or removing contacts, do not
spread or rotate tool tips.
CONTACT REMOVAL
3. Insert plastic or metal removal tool into
contact cavity until tool tips enter rear
grommet and come to a positive stop. Hold
tool tip firmly against positive stop on
contact shoulder. Grip wire and simultane-
ously remove tool and contact. (On occa-
sion, it may be necessary to remove tool,
rotate 90° and reinsert.)
1. Remove hardware from plug or
receptacle and slide hardware back
along wire bundle.
2. Use proper plastic or metal
removal tool for corresponding
contact. (Consult tool table on page
277). Slide correct size tool over wire
insulation.
Use white end of plastic tool for
removal of contacts.
Removal of contacts with metal tool.
