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.
All popular series of Amphenol cylindrical 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 24 for coax contact performance data.
Matched impedance size 12 coax contacts are also available (see page 28).
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.
CONCENTRIC TWINAX
SHIELDED CONTACTS
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
cylindrical connector and does
not require contact polarization
within the insert. Size 8 concen-
tric 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.
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 contact
conductor to the shell. They are sold “less contacts”
