Twinax, Triax Contacts

Amphenol Twinax contacts are designed for use with Twinax cable (shielded twisted pair). Amphenol Twinax contacts provide protection against magnetic interferences and electrostatic interference, including nuclear electromagnetic pulse. These contacts maintain shield integrity through a multi-pin circular connector

FEATURES AND BENEFITS

  • Protection against magnetic interferences
  • Protection against electrostatic interference, including nuclear electromagnetic pulse
  • Maintains shield integrity through a multi-pin circular connector
  • Does not require contact polarization within the insert (concentric interface)
