Cannon 75 Ohm Connectors
QT-BNC
This innovative termination technique provides the QT-BNC with
a high 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
central contact and rear crimp ferrule. This connector may be
terminated onto cable in under 20 seconds, significantly
reducing installation costs.
Applications
• Central Office Switching • Cross Connect Equipment • Telecommunications
