Bulkhead to VITA Inside-The-Box Cable Assemblies

SV Microwave's new IP67 Bulkhead-to-VITA 67.3 cable assemblies provide a robust, inside-the-box solution for routing RF signals in embedded systems applications. These 12-inch assemblies are provide a secure, sealed transition from a box’s exterior to its internal backplane.

One end features a threaded, gasket-sealed SMA bulkhead connector, rated to IP67 for protection against dust and water ingress. The other end is terminated with a standard VITA 67.3 backplane contact (NanoRF, SMPM, or SMPS), allowing for direct connection to plug-in cards and enabling modular system designs.

Available with either flexible .047" or a less lossy .085", these assemblies ensure high-performance signal integrity for demanding applications.
