BNC Connectors

Features & Benefits
  • Bayonet coupling mechanism provides quick mating and unmating
    		•
  • 50 Ω and 75 Ω impedance designs allow customers to match impedance to system requirements
    		•
  • 50 Ω and 75 Ω connectors are intermateable to ensure non-destructive mating
    		•
  • Three grades of connectors are available for military, industrial and commercial applications
