Smiths Connectors  High Frequency Coax Contacts are engineered with a “float mount” design to assure high performance (low VSWR) at microwave frequencies by preventing any air gap at the mating interface. These contacts are to be terminated to .086 diameter flexible cables. 

  • Socket contacts are spring loaded float mount
  • Rugged interface works even if misaligned
