Neutrik NBB75FI Bulkhead-Mount Bnc / Bnc Iso



Isolated BNC cable jack for panel mount, feedthrough
Neutrik’s BNC cable jacks for panel mount 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.

Features and 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)
Extra wide fastening nut avoids damaging the plastic thread

New cage type contact

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