High Speed Coax and Twinax Contacts
Optional choices, other than standard crimp or solder 500 cycle and 1500 cycle
contacts, are often required for high frequency interconnections. Amphenol
offers shielded contacts for RF applications as well as balanced high sensitivity
circuits.
SHIELDED COAXIAL
CONTACTS
High speed Coax contacts within
a connector provide the shielding
protection, and many cases the
RF/microwave performance,
needed in the circuitry of many
applications.
Shielded Coax Contacts
All popular series of Amphenol circular connectors
and many rectangular 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 contacts in connector arrangements which include
those sizes. Popular RG cable types and a variety of other commercial coaxial
cables can be accommodated. See page 390 for coax contact performance
data. Matched impedance size 12 coax contacts are also available
(see page 394). 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 environmental integrity through the grommets
and seals used, and coaxial junction is protected by the connector outer shell.

Amphenol^® Shielded Contacts
provide design versatility for
electrical circuitry. Shielded
contacts are used to eliminate interference from
outside electrical sources, when standard crimp
or solder contacts are not enough.

High performance shielding
capabilities are available with
Concentric Twinax contacts.
These are designed for protection
from magnetic and electrostatic
interference including nuclear
electro-magnetic pulse. The
contact is crimp terminable to

twisted shielded cable and is fully
scoop-proof (recessed pins) in
MIL-DTL-38999 connectors. The
concentric twinax contact is
engineered to maintain shield
integrity through a multi-pin
circular 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

Connector with Concentric Twinax
Contacts, Qualified for MIL-STD-1760
with its fully scoop-proof feature

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.
Size 8 & 12 coax, triax or twinax contacts or size 16 coax contacts are available
in Ground Plane Connectors (See photo preceding page). These are
MIL-DTL-38999 Series III connectors for data bus, LAN and coax/triax/twinax
transmission lines with conductive inserts that ground the outer conta₄ct
conductor to the shell. They are sold “less contacts”
