Conductive metal mesh strip securely crimped into
either one or both edges of a metal frame or mounting strip. Optionally
available with metal shielding strip on one edge and an elastomer pressure or weather
sealing strip on the other. Ideal for shielding sheet metal enclosures where
this semi-rigid gasketing provides ease
of mounting and added stability while, at
the same time, exhibiting high shielding
shielding and sealing with easy mounting
In one form of Frame
Knit Shield and Seal gasketing
a length of knitted wire mesh is securely crimped
onto the edge of an extruded
aluminum mounting strip. The mesh may be all metal
(Knit Shield), usually monel, SnCuFe, or
aluminum; or it may be metal mesh wound
on an elastomer core (Knit
Shield and Seal). The metal mesh provides
inherent high performance shielding
effectiveness and the elastomer, the extra resilience and a
partial seal against rain and dust. Alternately, the
metal mesh wire gasketing may be
inserted in both edges of an aluminum mounting strip, to provide
a solid frame mount and a double EMI/RFI shield; or the sealing gasket
strip may be plain elastomer
(silicone or neoprene) to provide a separate pressure or weather
When the extruded
aluminum frame strip is utilized, it serves as a convenient means for mounting by
bolting, or attaching via sheet metal screws. In addition, the
mounting strip may serve as a compression
stop to prevent undue pressure on the
metal mesh gasket. It also stiffens the surface
to which it is attached, thereby serving as a load-bearing element in the
structure, capable of meeting exacting shock and vibration requirements.
Product supplied in custom fabricated strips and
Knit Shield and Seal gaskets are commonly supplied
in custom fabricated strips or frames ready to
install. Holes are drilled, or other machining
performed as required. It can also be provided in bulk
lengths, fabricated to the customer's specifications.
