CLIP-ON PERPENDICULAR SHIELDING
This product offers a clip-on design that permits shielding to a
perpendicular surface.
• Finger design allows for continuous contact across the length of
the strip
• Clip-on design is ideal where high temperature or other design
considerations preclude the use of adhesive-mounted gasketing
• “D” lance design provides excellent retention of gasket and
allows for a strong omnidirectional grip
• Supplied in a wide variety of plating nishes, see page 17
• Shielding effectiveness of > 80 dB for a 10 MHz plane wave.
• These 97-Series products are also available in UltraSoft
®
low
compression force 98-Series.

reduced compression forces.
• Designed to be applied to the top edge of multi-compartmental castings
with wall thickness from 0.035 in. (0.889 mm) to 0.055 in. (1.397 mm)
• Clip-on design allows for easy installation and secure retention
• Unique finger design provides extremely low compression force
• Excellent shielding and grounding properties
• Provided in standard 12.000 in. (304.800 mm) lengths, or easily cut to
your desired length. Longer lengths available upon request.

Laird Technologies introduces the Card Guide Clip-On, which offers excellent
grounding contact from the PC board to a card guide on a rack. The unique
snap-in feature of the contact finger prevents any potential snagging. This
allows for bi-directional sliding contact. The Card Guide Clip-On gasket installs
to the edge of the board and makes contact with ground trace on the card.
The card then slides into the card guide on the rack. Low compression forces
allow for easy installation of the card.
• Easily installs onto PC board
• Provides for bi-directional wiping that eliminates snagging
• Ideal, inexpensive solution for grounding applications
• High-performance beryllium copper can be plated with a wide
variety of finishes for galvanic compatibility, see page 1-11
• Designed for board thicknesses of 0.085 in. to 0.100 in.
(2.159 mm to 2.540 mm)
• Design capabilities available to handle other board thicknesses and custom
applications
• 97-983 is available with “D” Lance option
