RFI Shielding

RFI Shielding FAQs

• Why is RFI Shielding Important?

  Have you ever seen a credit card holder that provides protection from having your card number stolen?

  RFI shielding or Radio Frequency Shielding is a thin protection shield added to almost every electronic process known.  It is needed to prevent sensitive information from being stolen.  On a global scale, shielding is used to protect everything from military information to a multitude of electronic data sources from information leakage that could be devastating if used inappropriately.

• RFI Shielding vs. Magnetic Shielding?

  RFI Shielding is most often thought of when describing an enclosed area. The shield block radio waves from penetrating the enclosed object.

  Magnetic Shielding prevents or isolates the magnetic field of a magnet.  The purpose is to stop interference of the magnet on any electronics that may be nearby.

• What is an RFI Shielding Wrap/Sleeve?

  Cable assemblies and electrical wiring needs to be wrapped or contained in a sleeve containing a metallic coating.   This will protect the wiring from magnetic and radio frequencies that may interfere with what is being transmitted.
