Neutrik's BNC chassis connectors offer a true 75 Ω design for serial and digital (HD) signals. The machined brass connector body provides an extremely rugged and non-abrasive connection over long term use and is in addition recessed and therefore well protected in a D-shape housing (audio industry standard).


Isolated BNC chassis connector, feedthrough in nickel D-shape housing


Features & Benefits

  • Gold plated cage type center contact
  • True 75 Ω design meets the stringent HD requirements
  • Isolated panel mount (solves potential grounding problems and prevents common-mode influence with other connections conducted over the same panel ground potential)
  • Standard D-shape housing - provides flush mounting and protection from demage
  • Color coding possible


New cage type contact

  • Closed contact design - extremely robust
  • Gold plated cage type clip - best possible shielding and lowest contact resistance
