This catalog covers the Amphenol ®/Matrix ® MIL-C-
26482, Series 2 Connectors. These connectors are
bayonet coupling type, and they feature crimp con-
tacts that are rear insertable and rear releasable. They
can be ordered through Amphenol, by military or
equivalent proprietary part numbers.
The Matrix ® connectors covered in this catalog
broaden the miniature cylindrical family offered by
Amphenol, so that now users have the broadest range
of product available to them. Additional miniature
cylindricals are covered in the Amphenol catalog, 12-
070, which is available upon request. The 12-070
Amphenol® catalog covers a large variety of miniature
cylindricals including the following:
MIL-C-26482, Series 1 - bayonet coupling connec-
tors with solder contacts
MIL-C-26482, Series 1 - bayonet coupling connec-
tors with front release crimp contacts
Other proprietary crimp and solder types including
hermetics and connectors with printed circuit board
contacts, as well as other shell styles, alternative
connector finishes and additional contact options
Additional miniature cylindricals that have double
stub threaded coupling rather than bayonet coupling
See page 15 for more information on these additional
miniature cylindrical connector products.

Amphenol broadens th eir Miniature Cylindrical Fam ily of
Connectors with the addition of the Matrix® Product line
of MIL-C-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 confirmation of complete coupling
Eliminates mismating by the use of five key/keyway design
Insertion and removal of contacts from the r ear of the c on-
nector 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 MIL-C-39029 requirements – BIN
coded (three color bands), and are crimped with standard
crimp tools per MIL-C-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 flange, jam nut
single hole mount, and cable connecting receptacles,
along with standard plugs or plugs with RFI grounding fin-
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 finishes are available (for information on non-cad-
mium zinc alloy plating, consult Amphenol, Sidney, NY)

PERFORMANCE SPECIFICATIONS
** Service Rating is comparable to MS rating A. Miniature connectors rated Service Rating I will provide a minimum flashover
voltage at 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.

INSERT ALTERNATE POSITIONING
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.

Miniature Cylindrical
Proprietary/MIL-C-26482, Series 1 & 2
Connectors
There ar e several additi onal c onnec tor series within
the Amph en ol® M IL - C-26482 an d s im il ar t yp es fam -
ily. Each series offers varying design characteris-
tics and customer options to meet cost
considerations and to provide users with the most
design flexibil ity poss ibl e.
The additional series within the Amphenol Miniature Cylindrical
Family of Connectors are shown in detail in Amphenol catalog
12-070, which can be s upp li ed upon request. Bri efly thes e add i-
tional products are described as follows:
PT, SP, MS/PT
Proprietary/MIL-C-26482, Series 1
These are bayonet type with solder contacts. Both the insert
and main joint gasket are molded from resilient neoprene.
This provides excellent moisture sealing at the gasket and
superior electrical isolation of the contact in the inserts.
Socket contacts are closed entry design. Printed circuit
board contacts are also available in this series.
The SP is a modification of the PT providing special shells
with a wide mounting flange for back panel mounting. The
SP also has a durable non-conductive hard anodic “Alumi-
lite” coating which provides abrasion and corrosion protec-
tion.
There are 8 s hell sty les in the PT, SP and MS /PT serie s, and
shell sizes are 6-24. The PT solder is UL recognized. Her-
metics are also available.
PT-SE, SP-SE, MS/PT-SE
Proprietary/MIL-C-26482, Series 1
These are a derivative of the PT line, bayonet type. How-
ever, they incorporate crimp contacts that are rear insert-
able, front releasable. An MS approved spring tower
rete ntion system holds the contacts in place.
PT-CE, SP-CE
Proprietary crimp type
Another derivative of the PT line, bayonet type. These also
have crimp contacts that are rear insertable, front releas-
able, but the contacts are held in place by a nylon wafer
retention system. The voidless one-piece insert and grom-
met assembly provide continuous dielectric separation
between contacts.
PC, PC-SE, PC-CE
Proprietary solder and crimp type
The PC series within the Amphenol® miniature cylindrical
family is threaded coupling, rather than bayonet coupling.
The threads are double-stubbed so they can not be cross
threaded.
The PC is offered with solder contacts. The PC-SE has
crimp contacts in a spring tower retention system, while the
PC-CE has c rimp co ntacts in a n ylon waf er retenti on sys tem.
Hermetics are available
All miniature cylindricals are intermateable and intermountable
with each other except f or the threaded coupling PC Series.
For further information ask for catalog 12-070. Consult Amphe-
nol, Sidney, NY for any assistance on these products or for any
specif ic applicat ion needs .
