Feed-through

Illustrated explanation

Continue the shield at penetrations and seams

1Feed-through
Continue the shield at penetrations and seamsCallout 1: Feed-through. Callout 2: Conductive seam gasket. A feed-through crosses the enclosure wall with defined conductor and shielding interfaces. A conductive gasket closes an electromagnetic seam when installed with the required contact. Current term: Feed-through, callout 1. 1Wall interfaceFeed-through 2Conductive seam gasket
  1. Feed-throughThis term

    The component carries a circuit through the boundary. Specify its electrical, shielding and environmental functions independently.

  2. Electromagnetic gasket

    The gasket creates a controlled conductive contact along the seam. Contact pressure, surface condition and mounting affect the shielding result.

A feed-through crosses the enclosure wall with defined conductor and shielding interfaces. A conductive gasket closes an electromagnetic seam when installed with the required contact.

Conceptual interfaces. Electrical filtering, sealing and EMC functions must each be confirmed; conductive appearance is not a test result.
