BNC feedthrough connectors and cables are available in vacuum-side and air-side types. Each single-ended model (BNC/BNC50/BNCF50) has dedicated vacuum-side connector and cable models. For double-ended BNCD feedthroughs, both sides share the same connector form factor. The vacuum side supports 50 Ω impedance-matched coaxial cables for improved signal quality. Cable length is customizable.
