General Description

AMPHENOL COAXIAL CONTACTS
TYPICALSUBMINIATURE
COAX SOCKETCONTACT

Offer several advantages for reliable interconnection andcontinued performance:• Large crimping area assures low contact resistance andhigh tensile strength• Back insulator positively captivates inner contact against
axial loads• Front insulator provides closed entry for socket inner contact• Recessed inner contact is protected• Outer contact has rugged wall section for durability

Matched Impedance Coaxial Contacts
for MIL-DTL-38999
12 COAXIAL CONTACTS FOR RF/MICROWAVE, HIGH FREQUENCY AND HIGH PERFORMANCE REQUIREMENTS
The matched impedance coax contact is available in size 12. It incorporates acaptivated inner contact which “snaps into” the outer contact preventing
displacement or pull-back of the inner contact in situations where thecable may be bent.
Design features and benefits of the Matched Impedance:• For use in 90 degree angle or bent cable applications• Provides 50 Ohm and 750 Ohm matched impedance
resulting in low VSWR and low insertion loss
• Frequency range for a mated pair extends to 3 GHz andbeyond, higher than other coaxial contacts previously offered• Ideally suited for D38999 high performance and MIL-STD-1760 				high band coaxial contact requirements

Concentric Twinax Contacts

General Description, Application Data - Size 8
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:
