The package inserts for two layers of woven mesh compression to the original height of 75%, get the best EMI shielding effectiveness, shielding effectiveness of a single layer of wire mesh will reduce the 5-10dB, more than two layers of wire mesh of the screen Not significantly improve efficiency.
This is a kind of woven wire mesh with elasticity and conductivity of porous elastic materials, a better combination of compression and deformation characteristics of a product. It is outside the core in the matrix material wrapped one, two woven wire mesh.

Standard wire material is Monel (a nickel copper alloy) and Ferrex (tin, copper-clad steel). Other metals and alloys (such as aluminum mesh) also apply to
Monel (most used, because it has good aging properties, tensile strength and spring-like quality.
Ferrex provide the best shielding performance, especially in the H-field, but the corrosion resistance is limited.
Standard foam core materials include neoprene (MIL-R-6130, Type 2) hollow solid neoprene (MIL-R-6855, grade 2), closed-cell silicone foam (AMS-3195) and solid silicone hollow Tube (ZZ-R-765, Level 2B)
In addition to the standard set out in almost any elastomer core sections are capable of producing, including the UL94V-0 to determine the core material.Listed in Table 2-6 in accordance with the provisions of material number and length needed to order, usually lining the length of the coil to a continuous supply.
Note: The core of the MESH STRIP elastomer lining is not easy to pad connected inseparable. For this reason, the lining should be processed in the factory specifications for custom sizes.
The lining of fabricated - by item number in Table 2-6 to determine the material. Provide the required size of the sketches lining, if possible, including shielding / sealing applications, a brief description.

Rectangular body (mm)
Overall width, single-round with flash
Diameter of 12.70 ± 0.79
Diameter of 12.70 ± 1.19
Note: These dimensions and tolerances for elastomer core material, the lateral size or diameter, including the grille, you can get along plus 0.79mm.
