Coax, Twinax & Triax PC Tail Contacts

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 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 show the available PC Tail contact part

numbers for 38999 Circular connectors See page 265 & 266

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
