Micro D-Twinax Transition Adapters
Amphenol now offers differential twinax transition adapters in smaller
sizes that provide matched impedance interconnection to PCB boards.
PDS-215-1
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
Micro D-Twinax Transition Adapters

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
