Knitted Wire Mesh0 pages
Knitted wire meshes are produced from a single
continuous filament and produce very high levels
of EMI shielding performance when evenly
compressed between two metallic contact
surfaces.
Our KP Shielding meshes are available in four
basic wire types - Monel, Aluminium, TCS (Tinned
Copper-clad Steel) and Stainless Steel. Each has its
own specific characteristics but TCS is generally
regarded as the most suitable for EMP (low
frequency) shielding.
KNITSHIELD Knitted Mesh
KP Shielding
Applications:
Because knitted wire meshes are not as resilient as elastomer cored
meshes (see KE Shielding), and will eventually take a compression-set,
they are generally used where the panel mating surfaces are perma-
nent or fixed.
KP meshes provide only limited environmental sealing so are normally
used for applications that are not exposed to the elements unless they
are protected by a further external elastomeric seal (see KC Shielding).
They do, however, have a long service life and a high temperature
tolerance.
For optimum effectiveness knitted mesh gaskets should be
compressed by 20 - 25% of their relaxed height. If surface irregularities
prevent this, an elastomer cored mesh (KE Shielding) would be more
suitable.
Gaskets can either be retained in a groove or channel or fixed with
adhesive (the wire contact points can penetrate a thin film), welding or
soldering.To facilitate clamping or riveting,'round-with-tail'and
'double-round-with-tail'sections are available.
