NBB75DFGX 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 Specifications Connection Type BNC 75 Ω Gender female Electrical Contact resistance ≤ 3 mΩ (inner) Contact resistance ≤ 2 mΩ (outer) Dielectric strength 1.5 kVdc Impedance 75 Ω Insulation resistance > 5 GΩ Rated voltage < 50 V VSWR ≤1.06 / >30 dB up to 6 GHz ≤1.13 / >24 dB up to 12 GHz ≤1.22 / >20 dB up to 18 Ghz Signal type UHD, SDI, Video, AES/EBU, Composit, YUV, RGB, RGBH, RGBHV Mechanical Insertion force < 25 N Lifetime > 1000 mating cycles Locking device Bayonett Mounting direction Front mounting Chassis shape D Material Contacts Brass (CuZn39Pb3), 0.2 µm AuCo (center contact) Insert PTFE Shell Polyacetal (POM) (insulation shell) Shell plating Antraloy D-shape housing Zinc diecast (ZnAl4Cu1) Environmental Temperature range -30 °C to 85 °C
