(2) These standard beryllium copper contact gaskets offer ideal RFI/EMI shielding of doors and movable components in electronic shielded rooms, trailers, computers and communication equipment. They have been scientifically designed for wiping closures, but are also usable in compression applications. Moreover, these contact strips feature extremely good endurance life, as well as a high deflection range. In tests, attenuation up to 112 dB has been measured for a 100 MHz plane wave. Fastening of the strip is usually accomplished using screws or rivets. Soldering is optional. Both are available in continuous lengths to a maximum of 25.0 ft. (7.6 m) and in all standard finishes. These 97-Series products are also available in UltraSoft low ...
Mechanically balanced strips with high deflection range and long endurance life-provide a perfect fit as spring clips hold the gaskets firmly in place. It means more simplified design and construction of cabinets and enclosures. Attenuation > 102 dB for a 100 MHz plane wave has been measured using Series 97-436 gaskets. These 97-Series products are also available in UltraSoft low compression force 98-Series.
Designed for use with Series 97-436 finger gaskets, spring clip fasteners permit full strip compression. Easy to install, they permit lifting of gasket for cleaning of contact surface. Packaged in lots of 1,000. Available in standard finishes.
(4) This version of Sticky Fingers beryllium copper shielding gaskets features a special U-shaped end that permits the finger of the strip to slide when enclosure doors are closed. It also retains the strip’s fingers when enclosure doors are open, thus preventing accidental damage to the fingers. Shielding effectiveness is > 115 dB for a 100 MHz plane wave. Four models provide you a choice of widths to suit your application. They are available in standard 16.000 in. (406.400 mm) lengths, except 97-515 which is furnished in 24.000 in. (609.600 mm) lengths. Also, all styles are available in continuous 25.0 ft. (7.6 m) coils, and in your choice of all finishes except tin lead and satin tin These 97-Series products are also available in ...
(2) Series 97-941/921 are low compression, flexible beryllium copper contact strips for applications where a continuous shield must conform to irregular shapes and turn tight radius corners in either direction. Simple snap-in installation is possible for Series 97-921 with 0.250 in. (6.350 mm) slots and 97-941 with 0.190 in. (4.826 mm) slots. However, soft solder or conductive adhesive can be used for mounting to flat surfaces. Shielding effectiveness is > 115 dB for a 100 MHz plane wave. Available in standard 24.000 in. (609.600 mm) lengths in all standard finishes.
(10) Adhesive-mounted beryllium copper contact strips Twist Series 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 ...
(4) Laird Technologies announces the addition of a battery contact product line. These high-performance battery contacts are suitable for coin battery applications, battery pack contact applications and AA/AAA battery applications. Supplied in heat treated beryllium copper, the contacts offer superb contact force and a large compression range. Heat treatment of beryllium copper significantly reduces the material’s internal stress, thereby allowing a wide range of compression to accommodate variations in battery size and placement.
(32) Contact strips are used for grounding and shielding in high-frequency equipment and for forming large diameter contact rings. A wide variety of beryllium copper contact strips provides engineers and designers with flexibility in solving grounding and shielding problems. Various lengths, widths, thicknesses, contours and hole locations are possible for many of the standard catalog items shown here. These 97-Series products are also available in UltraSoft low compression force 98-Series. Contips, localized deposits of silver or gold used to enhance conductivity, are available for our contact strips and contact rings. Contips minimum thicknesses are: 0.003 in. (0.076 mm) for silver and 0.0003 in. (0.008 mm) for gold.
(33) The large variety of sizes and shapes of contact rings offers engineers a wide choice in meeting design requirements for microwave cavities, tuning, shielding and grounding applications. Rings are made from strip stock formed into an unclosed circle which, when assembled, becomes a complete ring. These rings are furnished in any diameter, greater than the minimum shown in the chart below, and must contain an integral number of fingers.
