Power Feedthroughs

Power Feedthroughs Used in High and Ultra High Vacuum Environments

MPF Power Feedthroughs transmit varying amounts of voltage and current from an external power supply into a vacuum chamber. We offer a wide variety of conductor sizes and alumina ceramic designs to satisfy the electrical system requirements. Our standard designs utilize copper, nickel, molybdenum, and stainless-steel conductors, and transmit between 500 and 100,000 volts.

  • Amperage

    Amperage (433)

    Categorized by amperage, these feedthroughs come in a wide variety of current ratings, mounting options, & conductor types, allowing you to find the exact feedthrough necessary for your application.
  • Voltage

    Voltage (400)

    Ranging from 500V to 100kV, these feedthroughs allow for a large number of uses; from low voltage signaling applications, to high voltage assemblies.

  • Power Glove (35)

    Power glove feedthroughs allow a quick & easy way to connect. They are paired with power glove connectors which both allow an easy connection, as well as increase the standoff of the feedthrough.

  • Non-Magnetic (2)

    MPF has created 100% non-magnetic feedthroughs. The designs have a magnetic permeability rating of less than 1.001. Our designs are constructed with titanium weld adaptors and copper conductors. They are sold in a weldable form that can be easily mounted to a titanium Conflat, KF/QF, or ASA type flanges. The copper conductors are rated for over 25 amps per conductor lead. The designs can be used from 1-2 KV per lead. They are 100% leak tested at 1x10 -9 cc/sec He and can be baked out to 450C for your Ultra-High-Application.
  • Watercooled

    Watercooled (51)

    MPF’s Watercooled power feedthroughs are often used in applications where high temperatures necessitate cooling. This includes high-amperage applications where the cooling allows more amperage to be pushed through the conductor without raising temperatures past specs.
