Neutrik - NBNC75BTU11X - The rearTWIST UHD BNC connectors are specifically designed for high resolution video signal transmissions.
The rearTWIST UHD BNC connectors are specifically designed for high resolution video signal transmissions. Due to the unique insulator and contact pin design, the connectors feature low return loss values for 4K and 8K signals.
Features & Benefits
- Optimized contact pin and insulator design for UHD-data transmissions
- Proven rearTWIST technology
- Swiss antraloy plating
- Fully compatible with conventional BNC chassis connectors
- Improved return loss values at high frequencies
Optimized Return Loss
Due to optimized insulator design and reduced crimp diameter from center pin the Neutrik rearTWIST UHD BNC 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.
For more details see Neutrik UHD BNC White Paper.
Crimp Dimensions
In order to achieve optimum return loss values at high frequencies the crimp dimension of the contact pin has been reduced.
| Pin: | 1.07 mm |
| Shield: | 7.36 mm |
| Crimp die: | DIE-R-BNCX-PU |
