Neutrik NBB75DFGX BNC UHD Grounded Chassis Connector Feed Through D-Shape Antraloy

BNC UHD grounded chassis connector feed through D-shape antraloy

Grounded UHD BNC chassis connector, feedthrough in antraloy plated D-shape housing
Neutrik’s UHD BNC chassis connectors offer low return loss values at high frequencies specific for high resolution video signal transmission. 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

Features and Benefits

Optimized gold plated cage type center contact for UHD signals as 4K or 8K
Swiss antraloy plating
Grounded panel mount
Standard D-shape housing provides flush mounting and protection from damage
Color coding possible
Fully compatible with conventional BNC cable connectors

Optimized Return Loss
Due to optimized insulator design the Neutrik rearTWIST UHD BNC chassis connector achieves increased headroom compared to conventional BNC connectors and offers additional return loss reserve for potential impedance deviations resulting from cable bending, incorrect connector assembly or faulty connection interfaces without signal interruption.
New cage type contact

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