Standard pressure-sensitive
adhesive attachment tape
(PSA) makes SOFT-SHIELD
5000 Series gaskets a user-friendly
and cost-effective design solution.
FEATURES
■ Typically requires <1 lb/inch (0.175
N/mm) closure force – 5 times lower
than other gaskets
■>90 dB attenuation from 20 MHz
to 10 GHz
■Asymmetrical profiles as well as
“C”, “V”, “P”, “D” shapes*
■Self-terminating fabric jacket
■No perfor mance degradation after
10,000 compression cycles
Seals
• Conductive elastomers • Knitted wire mesh
• Conductive coatings, sealants, adhesives
• Cable shielding products • EMI/ESD shielding laminates
• Shielded vents and windows

SOFT-SHIELD®5000 Series
Conductive Jacket over Foam EMI Gaskets
DESCRIPTION
SOFT-SHIELD 5000 Series EMI gaskets
are designed to meet the stringent
shielding and mechanical perfor mance
requirements of today’s commercial
electronic enclosures, medical electronics,
factory automation equipment, repro-
graphics and grounding applications.
SOFT-SHIELD 5000 Series EMI gaskets
consist of an electrically conductive
fabric jacket over a highly compressible
foam core. The nickel-plated-silver woven
nylon rip-stop jacket is self-terminating
when cut. Chosen for its exceptional
compressibility, the foam core typically
requires less than 1 lb/in (0.175 N/mm)
closure force, making it especially useful
for thin-walled plastic enclosures.
