RF Coaxial Connectors QT-BNC T his totally new 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 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 For more information: www.ittcannon.com/cat078 • Meets Telcordia/SMPTE 292M standards. • Designed for field installation. • Plastic rear cap is color coded for easy identification of cable type. • Optional right angle strain relief boot • Complete assembly instructions are printed • • accessory (shown above). Compatible with select competitive crimp tools and die sets. on bags. Pneumatic crimp tool available.
