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.
DESIGN CHARACTERISTICS
• 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
• Visual conrmation of complete coupling
• Eliminates mismating by the use of ve key/keyway design
• Insertion and removal of contacts from the rear of the
con nector assures no damage to the front that might affect
the sealing characteristics
• Utilizes same standard qualied rear-release type plastic
tool for contact insertion and removal
• Contacts are qualied to SAE AS39029** requirements
– BIN coded (three color bands), and are crimped with
standard crimp tools per MIL-DTL-22520
• 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
tri ple 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
con tact bent within pre-established limits
• Elastomer interfacial seal on the pin side has raised
barri ers around each pin which displace into the socket
cham fer when mated, providing a positive moisture seal
CUSTOMER OPTIONS
• Shell styles within this family include: Wall mount with
either a narrow or a wide ange, jam nut single hole mount,
and cable connecting receptacles, along with standard
plugs or plugs with RFI grounding n gers, in shell
sizes 8 to 24
• MS and Proprietary versions available
• Accommodation of contact sizes 20, 16 and 12
• 34 insert arrangement patterns available, accommodating
from a minimum of 3 to a maximum of 55 circuits
• Alternate positioning available
• Various nishes are available (for information on
non-cad mium zinc alloy plating, consult Amphenol
Aerospace)

ALTERNATE ROTATIONS OF INSERT
To avoid cross-plugging problems in applications requiring the
use of more than one connector of the same size and
arrangement, alternate rotations are available as indicated in
the chart below.
As shown in the diagram, the front face of the pin insert is rotated
within the shell in a clockwise direction from the normal shell
key. The socket insert would be rotated counter-clockwise the
same number of degrees in respect to the normal shell key.
Position W Position X Position Y Position Z

ashover 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)
ENVIRONMENTAL SEAL
Wired, mated connectors with the specied accessory
attached will meet the altitude immersion test specied
in MIL-DTL-26482.
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.
SHOCK:
Pulse of an approximate half sine wave of 300g magnitude
with duration of 3 milliseconds applied in three axes.
VIBRATION:
Sixteen hours of random vibration having a range of 50 to
2,000 Hz with a 41.7G peak level.
