Parker Chomerics SOFT-SHIELD
��
5000
Series gaskets offer a low cost and high
performance EMI gasketing solution for
commercial electronic systems. This product
has been obsoleted as of 2019 and has been
replaced with SOFT-SHIELD 3500. Cross
referenced part numbers can be found on
the last page of this document.
The high reliability conductive fabric
over foam core construction provides
a cost effective alternative to beryllium
copper or stainless steel fingerstock EMI
gaskets. Applications for these conductive
fabric over urethane foam core gaskets
include; commercial electronic enclosures,
medical electronics and general industrial
applications. The variety of available cross-
section profiles allow for very low closure
forces, thus offering a minimization of the
number of necessary fasteners for easy,
user friendly installation, without an effect
to shielding effectiveness. Cut-to-length
strips of gasket are self terminating thereby
enhancing the reliability of the application.
The urethane foam core has excellent
compressibility making the gasket material
especially attractive for thin-walled plastic
enclosures. Gaskets are offered standard
with a UL 94 V-0 flammability rating.
