Knitted wire mesh tape is used to provide EMI shielding for electrical and electronic cable assemblies. The tape is structured as knitted wire mesh in a double layer to provide the best shielding. Knitted wire mesh is a metal strand or wire which is knitted together to create a mesh-like structure. A mesh is best described as a structure similar to that of a web or net since it has many attached or woven strands.
The knitted structure is beneficial for EMI shielding since it is conformable and flexible while being lightweight. Knitted wire mesh tape is usually made up of selenium, copper, iron or monel wire to ensure the tape is most effective.
