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
• ARINC 404 and ARINC 600 rectangular connectors. Supplied by
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-
• Maintains shield integrity through a multi-pin cylindrical con-
• 175°C rated and meets performance levels of MIL-DTL-38999
• MIL-C-17/176-00002 cable termination
• Gold plated full crimp termination contacts qualified to M39029/
• Integral part of the MIL-STD-1760 interconnection system
• Also available in modified but intermateable versions for termi-
