Amphenol Backplane Systems UHD Coax Connector

Amphenol's UHD Coax connector has a high-performance impedance-matched contacts of 50 Ohms nominal at 0-2 GHz. It's integral guidance simplifies use in blind-mate applications. It can be easily incorporated in the UHD Backplane and module connector assemblies. It's controlled contact float provides accurate mating alignment and has become an industry-standard hand crimping tool.

Some specifications are as follows:

  • 292 Digital Contacts
  • SEM-E Format
  • DESC 89065
  • 8 Coax Contacts
  • Rigid or Flex Terminations
