PROEL NBB75DFIB - BNC Female Chassis Connector 75 Ohm (Through-through)
The Proel NBB75DFIB is the ultimate professional solution for system integrators, broadcast technicians, and sound engineers seeking absolute reliability in digital video and audio signal transmission. Designed to provide a robust, interference-free connection, this female BNC panel connector establishes itself as a critical component in any fixed installation, patch panel, or connection rack.
This connector stands out for its constant 75-ohm impedance design, an essential feature for ensuring the integrity of high-definition signals (HD-SDI, 3G-SDI) and preventing the return losses that often occur with lower-category connectors. Its precision construction ensures that the signal remains pure and stable, even over long runs of coaxial cable.
Its D-type housing format (compatible with the industry-standard D-Series) allows for quick and uniform installation on pre-drilled panels, facilitating mounting in television studios, mobile units, and stages. Furthermore, it features an isolated ground loop system, effectively preventing unwanted ground loops and hum, protecting both image quality and the safety of connected equipment.
Main features
-
Actual impedance of 75 Ω: Optimized for transmission of HD, UHD video and digital signals without degradation.
-
Ground isolation: The isolated design separates the connector ground from the panel ground, eliminating noise and ground loop problems.
-
Standard D Series Format: Universally compatible with standard rack panels, stage boxes, and wall plates.
-
Feedthrough Connection: Female-to-female system that allows connecting BNC cables terminated on both ends without the need for soldering, speeding up assembly and maintenance.
-
Durable construction: Robust body with corrosion-resistant nickel finish and gold-plated center contacts for superior conductivity.
Benefits for the professional
Using the Proel NBB75DFIB connector ensures peace of mind in critical environments. Its through-hole design eliminates the need for soldering, drastically reducing field installation time. The quality of its materials guarantees a long service life, even with frequent plug-and-unplug cycles, while its superior shielding protects the signal from external electromagnetic interference.
Use cases
-
Broadcast Studios: Connection panels for video matrices and mixers.
-
Fixed installations: Signal distribution in auditoriums, theaters and conference rooms.
-
Mobile units: Equipment racks for live broadcasts where reliability is non-negotiable.
-
Video surveillance systems (CCTV): Centralized connection of high-definition cameras in control rooms.
Frequently Asked Questions
-
Is this connector suitable for 50 Ohm cables?
Although they can be physically connected, it is not recommended for HD video signals, as this connector is 75 Ohms. Using the wrong impedance can cause signal reflections and a loss of image quality.
-
Does the connector require soldering?
No, this model is a feedthrough type. It has a female BNC connector on both the front and back, allowing you to connect pre-made cables directly.
-
Is it compatible with Neutrik panels?
Yes, the housing format is the "D Series" standard, so it fits perfectly into the same holes and panels as the connectors of that series.
-
What does it mean for it to be isolated?
This means the metal housing of the connector is not in electrical contact with the panel ground where it is mounted. This is crucial to prevent electrical noise known as "ground loops."
