All dimensions shown are in inches (millimeters) unless otherwise specified.
Laird Technologies alternating slot/cut design is designed for use in a wide
variety of slotted applications, such as front panel handles, plug-in units,
subrack assemblies, chassis covers and backplanes.
The alternating slot / cut design serves to enhance the gasket strength,
while providing enough flexibility to allow the part to be folded in half with
no resultant finger damage. This is especially significant in during installation
or repair.
Available in a wide variety of plating finishes to meet galvanic compatibility
requirements.
Available in UltraSoft
™
, low compression series (-078).

Laird Technologies offers a unique product designed to shield the front panels
of IEEE standard 1101.10 card cages, commonly referred to as Dot-10, called
the Compact PCI gasket.
This front panel shielding has been designed to shield between the front
panels on sub racks and plug-in units. This is a beryllium copper solid top
symmetrical slotted fingerstock strip pre-plated in sulfamate nickel. It is
designed to mount on the “T” shape on a front panel extrusion (see below).
Specially designed for wiping applications, this configuration allows total
symmetrical compression action with bi-directional engagement.
Standard size shown is based on the 9.5" (241.300) length per the Dot-10 standard.
Other lengths and plating finishes are available for your specific application.

VARIABLE SLOT MOUNT
Laird introduces Variable Slot Mount shielding, which eliminates the
use of long slots while still utilizing the easy installation method of
slot mount shielding. Fingers are removed from the strip in areas
where a mounting slot is not present. The Variable Slot Mount
shielding strips can be customized to any patterned series of slots.
• Easy and cost-effective installation since fasteners and adhesives
are not required
• Improved shielding effectiveness compared to traditional slot
mount series through elimination of long slots in host material
• Slot mounting feature can be varied to accommodate different
lengths and hole mounting patterns (see gure 2)
• Three and ve pitch segments ideal for grounding applications
• Bi-directional wiping and compression action to accommodate a
wide variety of designs
• Available in standard (77-Series) and UltraSoft
®
(78-Series low
compression versions)
• Ability to retrot equipment when higher clock speeds limit current
slot mount product without changing slot size or location
• One piece construction eliminates handling individual pieces,
thereby shortening installation time
• Ideal for grounding and shielding in the following electronic
enclosure applications:
– Front panel handles – Chassis covers – Backplanes
– Plug-in units – Subrack assemblies
