Neutrik NBB75DFIB Flush-Mount BNC / BNC: D-Size Isolated Black Housing


Isolated BNC chassis connectors, feedthrough in black D-shape housing
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).

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 damage
Color coding possible

New cage type contact

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