IP67 Sealed Cable Assemblies Amphenol RF Sealed Cable Assemblies are TNC and SMA assemblies providing IP67 protection against dust and moisture and constant 50Ω impedance. The TNC assemblies feature threaded miniature connectors that are weatherproof and offer a frequency range of DC to 11GHz. The TNC threaded coupling interface does not de-couple during intense vibration. The TNC assemblies offer versatility and durability. The SMA semi-precision, high-frequency connectors are sub-miniature and offer reliable broadband performance. The SMA assemblies are available in between-series and in-series configurations and include flexible and semi-rigid (hand-conformable) cable types. Amphenol RF SMA assemblies on semi-rigid cables offer DC to 18GHz and assemblies using flexible cables perform up to 12.4GHz, with both cable types offering low reflection.
