The recommended operating compression for Fabric-Over-Foam EMI
Gaskets will vary depending on the shape and size of the particular gasket.
Typically, D-Shaped, Rectangular Shaped, and Square Shaped Fabric-Over-Foam
EMI Gaskets should be compressed between 30 % and 50 % of the foam height.
Similarly, C-Shaped Fabric-Over-Foam EMI Gaskets should typically be compressed
between 50 % and 75 % of the gasket height.
* Certain combinations of materials may not be available for all Profiles or I/Os.
Diverse Assembly Options
Multiple attachment options provide a variety of ways
to install critical EMI products. Pressure Sensitive
Adhesive (PSA) has been complemented with the
Easy Peel
configurations. These mechanical attachment options
enable you to take advantage of existing tooling on
doors and enclosures as well as offer alternate attach-
ment methods to better meet design requirements.
Profile Gasket Tolerances
For parts shorter than 1 inch (25.4mm), or longer than 96" (2438.4mm), please consult Engineering for
tolerances. See back cover for contact information.
