NEUTRIK 75
Ω
BNC Connectors
Neutrik offers a variety of 75
Ω
cable and chassis BNC connectors. The rearTWIST cable connectors are easy to handle in high
density applications such as video patchbays and switches, provide a tactile and fast assembly and offer colour coding as a
standard. All parts of our BNC series are precisely machined to our high quality standards.

With the introduction of HD signals the impedance of BNC connectors
becames more important than ever. Every deviate impedance has a
negative influence on the "return loss" / "VSWR" (Voltage Standing
Wave Ratio) which are important measurements for reflected signals
in a transmission line. Especially on high frequencies - as they occur
when transmitting HD signals an impedance mismatch results in a lot
of return loss.
Neutrik´s BNC connectors feature a true 75
Ω
design that meet the
stringent requirements of HDTV and sustain a consistent impedance
at high frequencies up to 4.5 GHz. To achieve this result every Neutrik
BNC connector has been adapted to the measurements of a small group
of cables, this guarantees the best possible performance and a little
return loss.
The higher the frequencies the more pronounced is the „skin effect“,
which means that the energy moves to the outside of the conductor.
Therefore the plating of outer and center contact is more important
than on audio connectors with low frequencies - both contacts of our
BNC connectors are gold plated.
Neutrik BNCs - enhanced high
frequency shielding!
In times of rising frequencies the connector shielding becomes to an
important value in order to avoid EMI problems and crosstalking. Neutrik
BNC's take this fact into account and has been equipped with an opti-
mized ground contact design for maximum shielding effectiveness.
Gold plated ground contact with improved shielding effectiveness
optimized for high frequency HDTV signal up to 4.5 GHz.

Features & Benefits
•
Screen and cable jacket crimp instead of screen crimp only.
Grooved inner surface holds the cable jacket to prevent tearing braids.
•
Gold plated ground contact with improved
shielding effectiveness optimized for high
frequency HDTV signal up to 4.5 GHz.
•
rearTWIST boot for easy access
in high density applications.
•
Leading area: Avoids tilting due to side forces to
protect the contacts from deformation. Guarantees
a lifetime of min. 1`000 mating cycles!
Neutrik BNC:
no tilting due to side pull
