RF Coaxial Connectors QTTM BNC Introduction This totally new termination technique provides a high pressure, gas tight center conductor joint of exceptional mechanical integrity, without crimping the center contact. The QT BNC is a 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. With only two parts to handle, the assembly is simple and has no loose contact to drop or lose. The plastic rear cap on the connector body is color coded for easy identification of cable type. The optional Assembly Tool allows even faster and easier connector assembly. In one squeeze of the tool handles the center contact is terminated to the center conductor and the rear ferrule is crimped at the same time. The 75 V QT BNC is available for use with popular cables used in telecommunication and broadcast systems.
