Cannon offers a comprehensive range of RF connectors, including 50 Ohm and 75 Ohm options. The 75 Ohm line features Type 43 (SMZ), 1.0/2.3, 1.6/5.6, and BNC connectors. The CoSMIDTM (Coax Surface Mount MID) 75 ohm connectors utilize molded interconnect device technology, enabling the integration of multiple coaxial lines into a single surface-mountable module. This modular design allows for increased coax line density on card edges. Quick Termination (QT) connectors simplify cable assembly by pre-assembling the QT contact, eliminating the need for crimping or soldering the center conductor. The QT mechanism is activated with a provided tool in four simple steps: strip cable, assemble connector, press insulator, and crimp ferrule. The QT principle can also be applied to 50 Ohm products. Cannon also provides a precision cable assembly service for manufacturing and testing a wide range of cable/connector assemblies, supporting flexible, semi-rigid, and Sealflex 2 RF and microwave coaxial cables from DC to 40 GHz. FAKRA connectors for automotive applications are also available.
