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.

TWIST
UHD – BNC Connector
With the transition to 4K or even 8K-signals the impedance of BNC
connectors became more important than ever. Every deviate impedance
has a negative influence on return loss and VSWR (Voltage Standing
Wave Ratio) which are important measurements for reflected signals in
a transmission line. Especially on high data rates up to 24 Gb/s, as they
occur when transmitting ultra high definition (UHD) signals, an impedance
mismatch results in high return loss.
Neutrik´s new rearTWIST UHD-BNC connector is a specificlally for high
frequencies optimized BNC connector; based on the proven rearTWIST
technology. The unique insulator design in combination with the reduced
crimp diameter of the gold plated center pin allows UHD-data transmission
within the required return loss limits.

cable jacket to prevent tearing braids.
2 High frequency optimized insulator design for
UHD-transmissions.
3 Reduced pin crimp diameter for performance
improvement (return loss values).

•
“rearTWIST Principle” locking / unlocking using the easily accessible soft touch boot (Patent DE 100 48507)
•
Ideal for recessed bulkheads where access to the “head” of the connector might be an issue. These connectors turn from
the back and not the front.
•
Snug-fit center pin insert provides tactile feedback
•
Shield and jacket crimp technology prevents the problem of an exposed grounding braid on cable assemblies
•
Large version for RG 11 cable
•
Precise Swiss machined brass parts for outstanding durability
•
Accessories include color coded boots in 10 standard colors, crimp tool and dies
•
Sleek female cable jack e.g. for Y-cables
