All dimensions shown are in inches (millimeters) unless otherwise specified.

Laird Technologies offers the Divider Edge Shield, the latest addition to its

line of longitudinal shielding and grounding products. The Divider Edge Shield

is designed to accommodate the industry’s trend toward miniaturization and

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.

• 97-654 is available with “D” Lance option

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
