SHV-5 Coaxial for Ultrahigh (UHV) High In-Vacuum (HV) Applications
SHV-5 Coaxial Interface
The "Safe High Voltage" connector, usually referred to as an SHV-5 coaxial connection, is commonly used in conjunction with low noise 50-Ohm instrumentation lines. Accu-Glass SHV coaxial feedthroughs are constructed with either floating or grounded shields.
Floating shields provide two concentric conductors: one outer metal tube or shield conductor concentric with, and enclosing, a cylindrical center conductor. Both electrical paths are electrically isolated from the vacuum flange.
Grounded shields provide only one electrical path that is electrically isolated from the vacuum flange. With grounded shields, the shield and vacuum flange are electrically common.
Ultrahigh (UHV) or High Vacuum compatible coaxial cable assemblies are available to meet the needs of most in-vacuum, low noise instrumentation cable applications. The vacuum side of a grounded and floating SHV feedthrough consists of a 0.094-inch (2.4-mm) diameter conductor pin that mates perfectly with Accu-Glass' grounded or floating Accufast connector interface.
