The following pages show examples of standard I/O gaskets used
in computer and telecommunication applications. If you have
different requirements, our Engineering Department will design
your gaskets to the specifications you supply. We will design your
I/O from a fully detailed print, drawing file, or the actual panel to
which the gasket is to be applied.
I/O Gasket Tolerances
Height tolerance: ± .020" (±0.5mm)
Width tolerance: ± .020" (±0.5mm)
Length tolerance: ± .020" (±0.5mm)
Cutout tolerance: ± .020" (±0.5mm)
If different tolerances are required, please consult Engineering. See back cover for contact information.

gasket.
Space between required cutouts should match
or exceed 0.060" (1.5mm).
Distance from the edge of a cutout should be
at least 0.060" (1.5mm) from the edge of the
gasket. In most cases, a slot can be used in
place of a hole that is positioned too close to
the gasket edge.
All cutouts and locations are designed customer
specifications.
Pressure Sensitive Adhesive (PSA) and Extended Release Liner
(ERL) can be applied in parallel with the long edge of the
The recommended operating compression for Fabric-Over-Foam
EMI gaskets will vary depending on the shape and size of the
particular gasket. Typically, I/O gaskets should be compressed
between 30% and 50% of the foam height.
