Coax, Twinax & Triax PC Tail Contacts
for Subminiature Cylindricals
general description, application data
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 packag-
ing solution for limited space applications where connec-
tors are attached to printed circuit boards. High reliability is
assured with factory pre-assembled contacts and stan-
dardization termination to the board. PC Tail contacts are
available for MIL-DTL-38999 Series I and III cylindrical
connectors and also for ARINC 404, ARINC 600 and R27
rect angular connectors. The following pages (36 & 37)
show the avail able PC Tail contact part numbers for
Subminiature Cylindricals. See the Rectangular Section of
this catalog for information on twinax contacts for ARINC
Rect angular connectors along with compatible cable
termina tions. Consult Amphenol Aerospace for further
information on the applicable tooling for these contacts.
