RF Coaxial Connectors
QT-BNC
his totally new termination technique
provides the QT-BNC with a high
T
pressure, gas tight center conductor
joint of exceptional mechanical integrity,
without crimping the center contact. The
QT-BNC is a 75 ohm pre-assembled connector
with an integral center contact and rear crimp
ferrule. This connector may be terminated
onto cable in under 20 seconds, significantly
reducing installation costs.
Applications:
Broadcast Systems
•
Central Office Switching
•
Cross-Connect Equipment
•
•
Telecommunications
