Electrical Connectors are an essential accessory for users of electrical feedthroughs, enabling power or signal transfer between vacuum applications and external air-side instrumentation.

MDC offers a wide range of connectors engineered for air-side and vacuum-side service. Many connector types are either included with, or designed to pair with, standard electrical feedthroughs.

Additionally, MDC provides in-vacuum coaxial cable assemblies in multiple styles and configurations. Each assembly is manufactured from vacuum-grade materials, including:

Stainless steel braided shielding for durability and EMI resistance.
High-purity alumina ceramic (Al₂O₃) or Kapton® insulation for high-temperature operation.
Beryllium copper contacts for excellent conductivity and mechanical strength.
Aluminum or stainless steel terminations for long-lasting performance.

These assemblies are specifically rated for high-temperature (°C range) and ultra-high vacuum (UHV, <1x10⁻⁹ Torr / 1.3x10⁻⁷ Pa) applications.

Industry Applications

Electrical Connectors are used in industries where vacuum environments and high reliability are essential. Typical applications include semiconductor manufacturing, vacuum furnaces, thin-film deposition, aerospace testing, nuclear research, particle accelerators, and analytical instrumentation. By ensuring stable electrical connections under extreme vacuum and temperature conditions, MDC connectors enable precise, consistent performance in both research and industrial environments.
