• Twinax Contacts - shielded twisted pair of conductors, designed for digital high
speed data transmission systems.
• Triax Contacts - designed for shielded wire applications.
This catalog helps you determine the best coax, twinax or triax contact for your
shielded wire requirements. Contact data is given according to connector series as
follows:
• Contacts for Cylindrical connectors
• Subminiature (MIL-DTL-38999* types)
• Miniature (MIL-C-26482 types)
• MIL-C-5015 types and Heavy Duty Cylindricals.

Amphenol® Shielded Contacts
Provide Design Versatility for Electrical Circuitry
Optional choices, other than standard crimp or solder 500 cycle and
1500 cycle contacts, are often required for high frequency interconnec-
tions. Contacts frequently require shielding to eliminate interference
from outside electrical sources. Amphenol offers shielded contacts for
RF applications as well as balanced high sensitivity circuits.
AMPHENOL® SHIELDED COAXIAL CONTACTS within a con-
nector provide the shielding protection, and in many cases the RF/
microwave performance, needed in the circuitry of many applications.
All popular series of Amphenol cylindrical connectors and many rectan-
gular connectors are available with coax contacts.
Diameters are standardized in sizes
4, 8, 12 and 16 so that coaxial contacts
may be interchanged with power con-
tacts in connector insert arrangements
which include those sizes. Popular RG
cable types and a variety of other com-
mercial coaxial cables can be accommo-
dated. See page 7 for coax contact
performance data.
Matched impedance size 12 coax contacts are also available
(see page 8). The use of coax contacts within a connector, compared to
the use of individual coaxial/shielded connectors, offers advantages of
savings in space and weight and no cross-mating difficulties. Coax and
standard contacts may be mixed within the connector to meet special
signal needs. The connector itself offers further protection and environ-
mental integrity through the grommets and seals used, and coaxial
junction is protected by the connector outer shell.
AMPHENOL® CONCENTRIC TWINAX SHIELDED
CONTACTS offer high performance shielding capabilities for protection from
magnetic and electrostatic interference including nuclear electromagnetic
pulse. The contact is crimp terminable to twisted shielded cable and is fully
scoop-proof (recessed pins) in MIL-DTL-38999 connectors. The concentric twi-
nax contact is engineered to maintain shield integrity through a multi-pin cylin-
drical connector and does not require contact polarization within the insert.
Size 8 concentric twinax contacts were developed for use in MIL-STD-1553B
Airborne multiplex data bus applications. Ideal for this application need is the
high performance Tri-Start connector with its fully scoop-proof feature of
recessed pins. The concentric twinax contact is crimp terminable to twisted-
shielded cable.
Size 12 concentric twinax contacts were developed for SAAB. They can be
used in any size 12 cavity of D38999 I, II or III or SJT connector.
Amphenol® RCT (Reduced Component Twinax) contacts are another contact
termination solution for MIL-STD-1760 and MIL-STD-1553 Data Bus require-
ments. It features 3 user-assembled components and is available in size 8 and
size 10 contact sizes. Termination is completed in only two crimping opera-
tions.
Twinax contacts are covered on pages 12-15. Supporting application tools are
available for crimping as well as installation and removal of contacts from con-
nectors. Consult Amphenol, Sidney, NY for tooling information.

AMPHENOL® TWINAX CONTACTS FOR PRINTED CIRCUIT
BOARD APPLICATIONS Printed circuit tail twinax contacts provide a
cost effective packaging solution for limited space applications where con-
nectors are attached to printed circuit boards. They are available for MIL-
DTL-38999 Series I and III cylindrical connectors and also for ARINC 404
and ARINC 600 rectangular connectors. High reliability is assured with fac-
tory pre-assembled contacts and standardized termination to the board.
See pages 17-18 for performance data and ordering of PC tail twinax con-
tacts, and consult Amphenol for any further
information needed.
AMPHENOL® SHIELDED CONTACTS
FOR GROUND PLANE
CONNECTORS
Amphenol offers MIL-DTL-38999 Series III
connectors for data bus, LAN and coax/
triax/twinax transmission lines with conduc-
tive inserts that ground the outer conductor
of the coax, triax or twinax contact to the
shell. These connectors are sold “less
contacts”. They will accommodate size 8 & 12
coax, triax or twinax contacts or size 16 coax contacts.
AMPHENOL® SHIELDED TRIAX CONTACTS with three conductors
are designed for use with triax cable. Amphenol supplies Triax contacts in
sizes 8, 10 and 12 for use in MIL-DTL-38999 Series I, II and III connectors.
Triax contacts provide additional shielding when terminated to triax cable
having solid or stranded center conductors. See cable compatibility in the
Cable Usage Guide for Triax contacts on page 5, and see performance data
and ordering of triax contacts on pages 16-18. Each of the three conductors
of the triax contact is separated by dielectric insulation to isolate ground
planes and to improve shielding effectiveness.
All conductors are crimp terminated for high
reliability and ease of assembly. Triax contacts
may be specified for direct connection to
printed circuit boards. For maximum system
flexibility, triax contacts may be mixed with
coax, twinax and power contacts in a single
connector.

Amphenol® Matched Impedance Size 12 Coaxial Contacts
For RF/Microwave, High Frequency and
High Performance Requirements
The matched impedance coax contact is available in size
12. It incorporates a captivated inner contact which
“snaps into” the outer contact preventing displacement or
pull back of the inner contact in situations where the cable
may be bent.
Design features and benefits of the
Matched Impedance:
• For use in 90 degree angle or bent cable applications
• Provides 50 ohm matched impedance resulting in low VSWR
and low insertion loss
• Frequency range for a mated pair extends to 3 GHz and
beyond, higher than other coaxial contacts previously
offered.
• Ideally suited for D38999 high performance and MIL-STD-
1760 high band coaxial contact requirements

Twinax Contacts for Subminiature
Cylindricals
general description, application data - size 8
High performance connectors within the D38999 families are the most
commonly used connectors for incorporation of twinax contacts. These
connectors offer wide versatility in insert arrangements for not only con-
centric twinax contacts, but also coax, triax, PCB, wire wrap, thermo-
couples and EMI filter contacts.
Other connectors available with concentric twinax contacts:
• Wire Integrated Connectors (WICS) for Data Bus Systems. Consult
Amphenol Aerospace, Sidney, NY.
• ARINC 404 and ARINC 600 rectangular connectors. Supplied by
Amphenol Canada.
SIZE 8 CONCENTRIC TWINAX CONTACTS
The size 8 concentric twinax contact was developed for use in
MIL-STD-1553 Airborne multiplex data bus applications which
require high performance interconnect characteristics in multi-pin
connectors. Ideal for this application need is the high performance
Tri-Start connector with its fully scoop-proof feature of recessed
pins. The concentric twinax contact is crimp terminable to twisted
shielded cable. Features include:
• Provides protection from magnetic and electrostatic interfer-
ence including nuclear electromagnetic pulse
• Maintains shield integrity through a multi-pin cylindrical con-
nector and does not require contact polarization within the
insert
• 175°C rated and meets performance levels of MIL-DTL-38999
Series III connectors
• MIL-C-17/176-00002 cable termination
• Gold plated full crimp termination contacts qualified to M39029/
90 & /91
• Integral part of the MIL-STD-1760 interconnection system
• Also available in modified but intermateable versions for termi-
nation to a host of cables (See chart on next page)

Twinax Contacts for Subminiature
Cylindricals
general description, application data - RCT Contacts
Amphenol® RCT (Reduced Component Twinax)
Contacts - contact assembly and termination for MIL-STD-1760
and MIL-STD-1553 Data Bus requirements.
• 3 user-assembled components
• Available in size 8 or size 10 contact
sizes
• MIL-C-17/176-00002 and other various
cable termination
• Termination completed in only two
crimping operations
• Inner conductors stripped to common
length
The size 8 reduced component twinax con-
tact meets MIL-C-39029/90 and /91
requirements for intermateability and per-
formance, while reducing the number of
user-assembled components from seven
to three.
The reduced component twinax can be
installed in MIL-DTL-38999* Series I or III
connectors, and can be terminated to MIL-
C-17/176-00002 cable, with other cable
versions available with minor modifications.
(see chart below)
The inner conductors and outer barrel are
each terminated to the cable by a crimp
joint, so no costly assembly soldering oper-
ation is required.
As the inner conductors are stripped to a
common length, multiple measurements
are eliminated. Assembly instructions are
included in the packaging of the contacts.
* MIL-DTL-38999 supersedes MIL-C-38999

Miniature Cylindrical Connector
Overview
Amphenol® Miniature Connectors, a widely used, medium
sized connector series for military and industrial applications,
can incorporate shielded coax contacts. The Miniature family
is built around MIL-C-26482 specifications, with Mil-
approved and proprietary styles offered. Normal operating
voltage for Miniature cylindricals with power only contacts is
up to 1,000 VAC (RMS) at sea level.
Miniature Cylindricals offer these features for contact
termination flexibility:
• Several insert arrangements that can incorporate:
• Size 8 & 12 Crimp Coax contacts for Crimp type
• Size 8 & 12 Solder Coax contacts for Solder type
• Wide selection of connector shell styles and sizes
• Standard power contact options within the various connector
styles include: solder type, crimp front release, crimp rear
release
• Coax contacts are designed to the same high performance
standards as power contacts. Coax and power contacts may
be intermixed with no degradation of connector reliability.
• No mis-mating or cross-plugging with insert rotation and key-
way polarization.

GENERAL ORDERING INFORMATION
Amphenol Miniature Cylindricals are normally supplied with a full complement of power contacts, separately packaged. Coax con-
tacts are ordered by part number as referenced in the part number charts on the following pages of this catalog, and are substituted
for the power contacts at the time of the cable or equipment assembly. If the application is for coax only, the connector may be
ordered
less contacts
and no power contacts will be supplied. Installation instructions for the coax contacts for Miniature Connectors
are provided in Amphenol documents as follows: L-633 for solder type; L-613 for SE type; L-660 for CE type
HOW TO ORDER:
A. Select the coax contacts designed for the cable being used from the applicable charts in this catalog for each Miniature type (sol-
der, SE or CE).
B. Select a connector insert from those shown on pages 28 and 29 which will accommodate the quantity and size of coaxial con-
tacts needed plus any power contacts required. Note: Size 8S and 12S contacts are used with connector inserts through shell
size 18 only. For larger connector shell sizes, use size 8L contacts.
C. Determine the Miniature Cylindrical type, shell style, finish, service class and insert rotation required for your application, using
Amphenol Catalog 12-070. (Catalog is on-line at www.amphenol-aerospace.com)
D. Consult Amphenol, Sidney NY with the pertinent cable, contact, insert arrangement and connector style choices for complete
connector part number.
* Amphenol also offers Miniature Cylindrical Connectors, MIL-C-26482
Series 2 which are bayonet coupling with crimp rear releaseable and
rear insertable contacts. (Ask for Catalog 12-071) Currently these
connectors are not offered with shielded contacts, however, consult
Amphenol, Sidney NY for any future availability.

Amphenol® Heavy Duty Cylindrical
MIL-C-22992 Connector Family:
QWLD
• Designed for most power and control circuits
• Military MIL-C-22992 qualified versions and proprietary equivalents
See Catalog 12-052 for complete information on these styles.
QWL
• A more compact heavy duty design for industrial power and control appli-
cations
See Catalog 12-053 for complete information on these styles.
Standard MIL-C-5015,
Heavy Duty MIL-C-22992
Cylindrical Connectors Overview
Amphenol’s medium to heavy weight cylindricals include the MS/Standard
MIL-C-5015 series and the heaviest weight, largest size cylindrical is the
Heavy Duty MIL-C-22992 series. These time-tested cylindricals have been
used for several years. They are dependable general duty and environmen-
tally resistant connectors for military and industrial applications.
Shielded coax contacts, although more popularly used in 38999 types and 26482
types, can be incorporated into some arrangements of the 5015 and 22992 type
cylindricals. Shielded coaxial contacts within these series are considered MS
modifications to the MIL-spec connector and the coax contacts are pre-installed in
the connector. Normal operating voltage with power contacts only is up to 3000
VAC (RMS) at sea level for MIL-C-5015 cylindricals. The Heavy Duty types are
designed for high current capacity and have current ratings (with power contacts
only) of up to 200 amps.
Standard and Heavy Duty Cylindricals offer these features for contact
termination flexibility:
• Insert arrangements that can incorporate:
• Size 4, 8 & 12 Crimp Coax contacts, pre-installed in the connector
• Wide selection of connector shell styles and sizes
• Standard power contact options within the various connector styles include:
solder type, crimp front release, crimp rear release
• Coax contacts are designed to the same high performance standards as
power contacts. Coax and power contacts may be intermixed with no degrada-
tion of connector reliability.
Amphenol® MS/Standard Cylindrical
MIL-C-5015* Type Connector Family:
See Catalog 12-020 for complete information on these styles.
MS-A, MS-C, MS-E, MS-F, MS-R
• Produced in strict accordance with MIL-C-5015
• Threaded coupling, solder or crimp rear insertion contacts (coax
available in crimp type only)
• Class A, Solid Shell - intended for general connector usage
• Class C, Pressurized - for use on pressurized bulkheads or pressure
barriers
• Class E/F, Environmental Resisting - ideally suited for installation
where condensation, vibration and rapid changes in pressure or tem-
perature are considerations
• Class R, Lightweight Environmental Resisting - shorter in length and
lighter in weight than Class E
GENERAL ORDERING INFORMATION
Amphenol MS/Standard MIL-C-5015 type and Heavy Duty MIL-C-22992 type cylindricals are normally supplied with a full complement of power
contacts, separately packaged. Coax contacts are ordered by part number as referenced in the part number charts on the following pages of
this catalog, and are substituted for the power contacts at the time of the cable or equipment assembly. Coax contacts are pre-installed in these
series. Installation instructions for the coax contacts for these series are provided in Amphenol document L-650.
HOW TO ORDER:
A. Select the coax contacts designed for the cable being used from the chart on page 32 of this catalog.
B. Select a connector insert from those shown on page 33 which will accommodate the quantity and size of coaxial contacts needed plus any
power contacts required.
C. Determine the MS/Standard or Heavy Duty Series style desired. (See features of each series referenced above). The catalog referenced for
each series will guide you in determining shell style, finish, service class and insert rotation required for your application.

Coaxial Contacts for Standard MIL-C-5015,
Heavy Duty MIL-C-22992 Cylindricals
general description
Amphenol® Coaxial Contacts can be incorporated into MS/Standard
MIL-C-5015 Type Cylindrical Connectors and Heavy Duty MIL-C-22992 Connec-
tors. They offer the same durability advantages and design benefits for reliable
interconnection as the Amphenol coax contacts used in high performance
D38999 connectors. A variety of military and commercial shielded cables are
accommodated within these cylindrical series.
Other features of the coax contacts available for MS/Standard and Heavy Duty
cylindricals include:
• Several insert arrangements that can incorporate:
• Size 4, 8 and 12 coax contacts
• Advanced shielding wire technology in a rugged military connector
• Single connector with multiple coaxial connection eliminates cross-mating
• Positive contact captivation - especially important in these series with its much
higher coupling/uncoupling force
• Older shielded cable type availability

2. Cable center conductor must be visible through the inspection
hole in the inner contact wire well.
3. Crimp inner contact wire well using crimp tool listed in table.
C. 1. Carefully slide outer contact assembly over inner contact
assembly and under cable outer braid until inner contact butts
against insulator shoulder as illustrated. (Inner contact
assembly will snap into the locked position when fully assem-
bled inside the outer contact assembly).
2. Bring outer crimp ferrule forward over cable outer braid as
illustrated. (Continue to push the inner contact assembly fully
forward while bringing the outer crimp ferrule into position).
3. Crimp outer crimp ferrule using crimp tool listed in table.
( .156 Max. over ferrule after crimping). Trim excess braid
ahead of crimp ferrule, if necessary.
CONTACT INSERTION INTO CONNECTOR
Using insertion tool (part number M81969/8-09 or M81969/14-04),
insert contact assembly into rear connector grommet hole. Contact
must be aligned with hole and not inserted at an angle. Push forward
until contact is felt to snap into position within insert. Remove tool.
CONTACT REMOVAL FROM CONNECTOR
Position removal tool (part number M81969/8-10 or M81969/14-04)
around cable and slide tool down wire until tool tips enter rear grom-
met and come to a positive stop. Hold tool tip firmly against positive
stop on contact, grip wire and simultaneously remove tool, contact
and cable.

Additional Contact Styles
Amphenol provides interconnect solutions
GROUND PLANE CONNECTORS
MIL-DTL-38999 type connectors are available with
metallic inserts to maintain a common ground plane
for all twinax, triax or coax contacts contained in the
connector. This photo shows a special hybrid design of
a Ground Plane Connector with a standard Mil-spec
insert, designed for applications where the twinax con-
tacts are required to be bonded to a common ground
plane, but insulated signal or power contacts are also
required.
Amphenol has today’s broadest range of interconnection solutions for military,
commercial and industrial applications. As a worldwide Interconnection Product
Leader, Amphenol can meet not only connector needs, but also contact needs of
all types. In addition to the shielded contacts shown in this publication, many other
contact styles are available:
THERMOCOUPLE CONTACTS
Available for MIL-DTL-5015, MIL-C-22992, MIL-C-26482, MIL-C-26500, MIL-DTL-
38999, MIL-DTL-83723 and other series connectors. Thermocouples are
designed for temperature measuring applications, and are available in both pin
and socket configurations in alumel, chromel, iron and constantan materials.
Refer to each of the MIL series catalogs.
WIRE WRAP CONTACTS
Available for MIL-C-26482 and MIL-DTL-38999 series connectors. See catalog
12-090 (38999, Series I & II) for part numbers and dimensional data.
PRINTED CIRCUIT BOARD CONTACTS
In addition to the coax, twinax and triax contacts described in this publication,
Amphenol has a full range of printed circuit tail contacts for signal and power
applications. Available in both solder termination and compliant pin tails, they offer
significant savings in system installed costs. Catalog 12-170, Amphenol® Cylindri-
cal Connectors for PCB Applications, provides information on connectors avail-
able with PCB contacts which include MIL-DTL-38999, MIL-C-26482 and MIL-C-
5015 styles.
FLEX TERMINATION ASSEMBLIES FOR PCB APPLICATION
Flex circuits are available for MIL-DTL-38999, MIL-C-5015 and MIL-C-
26482, as well as for special products such as EMI/EMP filter connectors.
Flex termination assemblies are provided by the ACT, Advanced Circuit
Technology division of Amphenol. Sculptured Flexible Circuits with built-in
terminations plug into a printed circuit board and create a self-locking termi-
nal pad which eliminates the need for an additional interconnect to the
PCB. See catalog 12-170 and consult Amphenol for further information.
BRUSH CONTACTS
As mentioned in the Rectangular section of this publication, the Amphenol® Low
Mating Force and Amphenol® LRM Surface Mount Connectors utilize the Brush
contact design. The Brush or B3 contact is an alternative to fork and blade conven-
tional contacts. It provides superior electrical characteristics with multiple strands
of high tensile wire that are bundled together. 70% to 90% reduction in mating/
unmating forces is achieved over conventional contacts, and the brush contact
has proven durability and long contact life. See catalogs 12-035 for Low Mating
Force Connectors and L-2081 and L-2104 for LRM Connectors.
FIBER OPTIC TERMINI
Amphenol provides fiber optic termini for multi-channel MIL-DTL-38999 Series III
connectors and for Low Mating Force and LRM rectangular connectors. Amphenol
MIL-T-29504/4 & /5 qualified fiber optic termination types offer low loss character-
istics with high reliability and repeatability. Optical performance is maximized uti-
lizing the unique alignment methods employed in these termination systems.
Fiber optic/electrical hybrid combinations provide flexibility. See Amphenol® Fiber
Optic Products Catalog, 12-352.
RADSOK SOCKETS
The new RADSOK contact design is a hyperbolic, stamped grid configuration within the socket cylin-
der. As the male pin is inserted, axial members in the female socket half deflect, imparting high current
flow across the connection with minimal voltage loss. The new RADSOK contact design has been
incorporated into three of the large industrial families from Amphenol - the GT Series, the P-Lok Series,
and 5015 types. The new connector lines are called Amphe-Power® Connectors, reflecting the high
power amperage applications they are designed for. Enhanced with RADSOK sockets, these Amphe-
Power connectors can now handle up to 150% higher amperages. See Brochure SL-391
