Coaxial MHV Air-Service Cable Assemblies and Components

Connector to Connector air side cable assemblies are fitted with standard MHV connectors at both ends of an RG59B/U coaxial cable.  The cables mate directly with the air side of MHV feedthrough flanges.

MHV Connector is a standard air service connector without cable.

MHV Coaxial Interface

The 'Miniature High Voltage' connector interface is designed for low noise 50-ohm lines requiring higher voltage than is possible with a standard BNC interface. MHV coaxial feedthroughs are constructed in both grounded and floating shield configurations. Floating shield types provide two concentric conductor paths: an outer metal conductor tube (shield) concentric with, and enclosing, a cylindrical center conductor pin. Both paths are electrically isolated from each other and a mounting flange. Grounded shield MHVs provide only one path that's electrically isolated from the flange; where grounded shield and flange are electrically common. Vacuum side of single-ended grounded and floating MHV feedthroughs have a 0.094 inch (2.4-mm) diameter conductor pin that mates with grounded or floating AccuFast™ connectors.
