CLIP-ON SYMMETRICAL SHIELDING
The 97-636 and 97-637 Clip-On Symmetrical Shielding Gaskets have
been designed to function equally well in applications requiring sliding
movement or direct compression.
• Supplied with standard “D” lance ensuring secure holding power
when snapped into a prefabricated hole
• “D” lance provides both multi-directional grip and excellent
conductivity
• Wide radius prole allows for maximum contact with minimum
compression force
• Clip-On feature allows part to be used in high temperature
(above 250°F) applications where adhesives will not function
• Available in our UltraSoft
®
, 98-Series low force version
• Ideally suited for cardcage handles, PC board grounding or any
other application requiring clip-on feature and wiping action
• Shielding effectiveness of 100 dB @ 100 MHz
• Available in a wide variety of plating nishes, see page 17

Laird Technologies No Snag Series shielding gaskets offer the designer a low
compression, no snag design. Provided with Sticky Fingers
®
self-adhesive tape,
these beryllium copper shielding gaskets provide easy and secure mounting.
• Shielding effectiveness of > 100 db (77-012) and 80 dB (77-014)
for a 100 MHz plane wave
• Easy, cost-effective installation since fasteners are not required
• Ideal as an all-purpose contact strip for metal cabinets and electronic
enclosures
• Available in a wide variety of plated finishes, see page 1-11
•
Supplied in standard 24.000 in. (609.600 mm) lengths or other specified lengths
For load/deflection data, see page 2-33.
