A variant of BNC coaxial feedthrough with embedded pins for increased voltage rating. Features grounded shielding with non-fixed impedance matching. Available in single-ended MHV or double-ended MHVD configurations. Single-ended version uses a 2.4 mm conductor; double-ended version uses MHV interface. Rated at 5 kV max, 3 A. Operates from -200°C to 450°C under UHV (<1×10⁻¹⁰ mbar). CF16 flanges support 1 unit; CF40 flanges accommodate up to 4 single-ended units. Custom flange-feedthrough combinations and weldable versions available. Optional dual-end connectors and cables available.
