Amphenol^® Printed Circuit Tail Contacts
are currently supplied as follows:
• 8, 12 and 16 Coax
• 8, 10 and 12 Twinax
• 8 Triax (socket only)
PC Tail shielded contacts provide a cost effective packag­ing
solution for limited space applications where connec­tors are
attached to printed circuit boards. High reliability is assured
with factory pre-assembled contacts and stan­dardization
termination to the board. PC Tail contacts are available for
MIL-DTL-38999 Series I and III circular connectors and also
for ARINC 404, ARINC 600 and R27 rect­angular connectors.
The following pages (402 & 403) show the avail­able PC Tail
contact part numbers for 38999 Circular connectors. See
page 412 Rectangular Section of this catalog for information
on twinax contacts for ARINC Rect­angular connectors along
with compatible cable termina­tions. Consult Amphenol
Aerospace for further information on the applicable
tooling for these contacts.
