MHV Floating Shield Feedthrough on CF Flanges
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.

| Notes |
- Electrical ratings are maximum test values, with feedthrough's vacuum side at ≤ 1x10E-4 Torr. Feedthroughs are intended for instrumentation applications carrying low level signal voltage and current.
- PEEK is a polyether ether ketone thermoplastic.
- Overall assembly ratings must be adjusted to that of its lowest rated component. For cryogenic service, the lowest recommended temperature is -200°C
- Connectors and cables are not included with feedthrough and must be purchased separately.
