SMA Connectors

Components in this SMA section are sold as the most basic components.

SMA Connectors listed above are designed for use with Accu-Glass Products' TYP6, 26 AWG Kapton® insulated coaxial cable (PN-100720).  The use of any other coaxial cable will require modification to some of the supplied components.  For this reason, the use of other coaxial cables is not recommended.

SMA Coaxial Interface

The 'Subminiature Type-A' coaxial connector, referred to as the SMA coaxial interface, is commonly used in conjunction with high-frequency, low noise 50-ohm instrumentation signal lines. SMA 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 SMAs 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 SMA feedthroughs have a 0.094 inch (2.4-mm) diameter conductor pin that mates with grounded or floating AccuFast™ connectors. Vacuum compatible cable assemblies are fitted with Kapton® insulated 26 AWG, 50-ohm coaxial cable, with either Accufast™ connectors or gold-plated SMA connectors.
