The NBB75DFIB from Neutrik is an isolated BNC female chassis connector. It offers a true 75ohm design for serial and digital (HD) signals. The machined brass connector body provides an extremely rugged and non-abrasive connection over long term use. The chassis connector is well protected in a D shape housing made of zinc die-cast with black chrome plating. The isolated panel mount solves potential grounding problems and prevents common-mode influence with other connections conducted over the same panel ground potential.
