Twinax Contacts for MIL-DTL-38999

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, 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 circular

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)
