FINGERSTOCK GASKETS AND METAL GROUNDING PRODUCTS
As the world’s leading fabricator of fingerstock, Laird Technologies has developed highly
sophisticated, and often proprietary, shielding and grounding technology.
Our innovations are necessary to achieve outstanding combinations of performance parameters.
From a vast selection of product configurations, platings and mounting techniques, to a full range
of low compression force requirements and high transfer impedance characteristics, there is a
Laird Technologies gasket or grounding product just right for the job.
Adhesive-mounted beryllium copper contact strips with scientific twist
design offer narrow electronic gaskets for general shielding applications.
Different widths are available to suit your specific application for single
edge contact strips.
Also available are two 90 degree versions (Series 97-551 and 97-558) to
provide alternate mounting capability. Series 97-555, 97-558 and 97-559
provide shielding effectiveness > 100 dB for a 100 MHz plane wave, ideal
for all types of panel or electronic enclosures. Series 97-550, 97-551 and 97-560 provide shielding
effectiveness > 115 dB for a 100 MHz plane wave. Series 97-560 strips are especially suitable for
cabinets with panel divider bars. Their unique double-edge design permits panels to be removed
easily and replaced without damage to the installed strip.
All Twist Series strips are furnished in 24.000 in. (609.600 mm) lengths. Strips (except 97-551 and
97-558) are also available in standard 25.0 ft. (7.6 m) coils. Right angle product configurations are
not available in coils. All are available in your choice of finishes,.
COMBINATION ENVIRONMENTAL RUBBER GASKET
Series 97-556 and 97-561 are versions of 97-555 and 97-560, respectively, incorporating a Poron
®
rubber gasket to act as an environmental shield, offering a high degree of protection against dust
and moisture. All are available in your choice of finishes. These 97-Series products are also available
in UltraSoft
®
low compression force 98-Series.
