Embedded pin design with rated voltage up to 5 kV, 50 Ω impedance matching, and floating-ground shielding. Available in single-ended MHVF50 or double-ended MHVDF50 configurations. Single-ended version uses a 2.4 mm conductor; double-ended version uses MHV interfaces. Rated at 5 kV max, 3 A. Operates from -200°C to 250°C under UHV (<1×10⁻¹⁰ mbar). CF16 flanges support 1 unit; CF40 flanges accommodate up to 3 units. Custom flange-feedthrough combinations and weldable versions available. Optional vacuum-side and air-side connectors and cables available.
