LARGE ENCLOSURE SERIES
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, see page 1-11. For load/deflection data, see page 2-33.
These 97-Series products are also available in UltraSoft

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

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,

Also, all styles are available in continuous 25.0 ft. (7.6 m) coils, and in
your choice of all nishes except tin lead and satin tin, see page 17.
These 97-Series products are also available in UltraSoft

All dimensions shown are in inches (millimeters) unless otherwise specified.
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, see page 1-11. For load/deflection data, see page 2-33.

Patent No. 4,572,921
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,
see page 1-11. For load/deflection data, see page 2-33.

Laird offers its line of card cage shielding, designed to provide EMI/RFI
shielding between the chassis and the slot covers.
• Provides a single gasket solution for a multiple of slot covers
• Material thickness of 0.004 in. (0.102 mm) insures low closure force and
eliminates possible distortion of mating parts
• 18 contact fingers per rib provides contact points over length of the I/O
bracket shield
• Superior contact finger design faces the card cage portion insuring
snag-free insertion of add-in cards
• Stainless steel design provides galvanic compatibility to most enclosure
materials
• Adaptable tooling allows for 1-21 slot configurations with no tooling cost
• Variable rib widths are available upon request
To discuss your particular application, please contact our sales department.
HOW TO ORDER
All parts start with 009510 as the first six digits. The next two digits designate
the number of slots in the part. The last two digits will be 00 for all standard
configurations. Example: 0095-1018-00 represents an 18 slot part.
All dimensions shown are in inches (millimeters) unless otherwise specified.
