Amphenol now offers differential twinax transition adapters in smaller
sizes that provide matched impedance interconnection to PCB boards.
Our unique push-pull quick disconnect adapter design offers:
Advantages over traditional threaded type adapters
Launching of controlled impedance (100 ohm) signals for
high speed twinax contacts with push-pull quick disconnect coupling
Rugged construction, 100+ mating cycles for reliable and secure
data transmission
Miniature size for tighter spacing on boards
Intermountability with existing threaded solutions having the same
PCB tail footprint
Styles include:
• Plug - standard length and extended length options
• Straight PCB receptacle, 90° PCB receptacle
• Two jam nut receptacle styles - both with standard length and extended length options
• Bushing assembly 90° adapter (used with plug or jam nut receptacle)

90° bushing assembly is ordered separately.
Adapters are not included with bushing assembly.
Illustrations below show how the 90° bushing assembly
attaches to either a plug or a jam nut receptacle adapter.
Amphenol transition adapters are capable of terminating to additional
100 Ohm cables beyond what are listed in the charts on pages 1 and 2.
Cables need to have the following dimensions:
.0210/.011 Dia. stranded center conductor (26/30 AWG)
.045 Dia. max. inner wire insulation
.115 Dia. max. outer braid (round type preferred)
.150 Dia. max. jacket
Consult Amphenol Aerospace for other cable termination possibilities.
