MHV coaxial feedthrough connectors and cables are available in vacuum-ide and air-side types. Each single-ended model (MHV/MHV50/MHVF50) has dedicated vacuum-side connector and cable models. For double-ended MHVD feedthroughs, both sides share the same connector form factor. Single-ended MHV feedthroughs can be paired with special MHV connectors on the vacuum side. The vacuum side supports 50 Ω impedance-matched coaxial cables for improved signal quality. Cable length is customizable.

Note:

1.Cable length is customizable.

2.The vacuum-side grounded shield connectors vary for single-ended MHV, MHV50, and MHVF50 feedthroughs, with corresponding models MT145-CON-SMHV-VAC, MT145-CON-SMHV50-VAC, and MT145-CON-SMHVF-VAC.

3.When selecting a cable model for single-ended MHV series feedthroughs, the vacuum-side grounded shield connector must be specified: SMHV, SMHV50, or SMHVF.
