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

® low compression

force 98-Series.

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. For standard finishes, see page 1-11. For load/deflection

data, see page 2-33. These 97-Series products are also available in UltraSoft

low compression force 98-Series.

QUICK SPRING CLIP FASTENERS (97-445)

Designed for use with Series 97-436 finger gaskets, spring clip fasteners per-

mit 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, see page 1-11.
