Twinax Contacts for Subminiature
Cylindricals
general description, application data - size 10 &12
Amphenol®Twinax Contacts were designed for use with
twinax cable in Data Bus systems. Twinax contacts provide the
following benets:
Protection from magnetic interference• Protection from electrostatic interference including nuclear elec-• tromagnetic pulse
Meets parameters dened by MIL-STD-1553B• Maintains shield integrity through a multi-pin cylindrical connec tor and • does not require contact polarization within the insert
SIZE 10 & 12 CONCENTRIC TWINAX CONTACTS
The size 12 concentric twinax contact interface was developed for
JN1104 EuroFighter contacts, and can be used in any size 12 cavity
M38999 I, II or III or SJT connector.
Features:
Operating temperature –55°C to 175°C• Pins are scoop-proof• Meets performance levels of M38999 connector• 4 components, gold plated crimp termination• For use with a variety of cables (See chart below)•

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 lter contacts.
Other connectors available with concentric twinax contacts:
Wir• e Integrated Connectors (WICS) for Data Bus Systems. Consult
Amphenol Aerospace, Sidney, NY.
ARINC 404, ARINC 600 and R27 Series 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 qualied to M39029/90 & /91• Integral part of the MIL-STD-1760 interconnection system•
Also available in modied but intermateable versions for termi nation to • a host of cables (See chart on next page)

Amphenol® Triax Contacts provide additional shielding
when terminated to triax cable having solid or stranded center
con ductors. Amphenol supplies triax contacts in sizes 8, 10 and 12
and they are ideally suited for use in D38999 Series I, II and III
cylindrical connectors.
Features and benets of Amphenol triax contacts include:
Incorporates three conductors, designed for use with triax cable• Each of the three conductors are separated by dielectric • insulation to isolate ground planes
Shielding effectiveness is improved with two isolated shields•
May be specied for direct connection to printed circuit boards• May be mixed with coax, twinax and power contacts in a single • connector
