501 EMI Gaskets
Fabric-over-Foam
NI/CU POLYESTER TAFFETA FABRIC-OVER-FOAM
Laird Technologies’ Fabric-over-Foam (FoF) 501 EMI gaskets provide excellent EMI shielding
performance for customers where EMI issues occur. The 501 Series EMI gaskets are composed
of electrically conductive fabric wrapped around a soft urethane foam core. They are supplied with
either a conductive or non-conductive pressure sensitive adhesive (PSA), and can be equipped with
an Extended Release Liner (ERL) on the adhesive. The 501 Series is a halogen-free product that can
be created with cross-section profiles such as rectangle, D, C, P, T, knife, bell shapes, and others.
The gaskets can be further customized to an application by die-cutting, hole punching, notching, etc.
FEATURES
• Fabric-over-Foam gaskets are RoHS compliant
• Halogen-free per IEC-61249-2-21 standard
• Low surface resistivity of < 0.07 Ω/□
provides excellent conductivity
• Shielding effectiveness of >100 dB across a
wide spectrum of frequencies
• Extremely low compression forces allow for
use of lighter materials
• Fabric is highly conductive to provide good
EMI shielding and grounding
• Abrasion resistant metallized fabrics
show virtually no degradation in electrical
performance after 1,000,000 cycles
• Laird Technologies’ proprietary coating
prevents fabric fraying and fingerprinting
• Available with conductive or
non-conductive PSA
• Many cross-section profiles available such as
rectangle, D, C, P, T, knife, bell and more
• Profile gaskets can be cut to specified lengths,
kiss-cut on release liner, or mitered to form
frame configurations
