Knitted Mesh Tape is a double-layered strip of knitted wire mesh providing an effective EMI shield for electrical and electronic cable assemblies. The knitted construction maximizes conformability and flexibility while minimizing bulk and weight. Knitted mesh tape uses Sn/Cu/Fe knitted or Monel wire to provide good physical strength and shielding effectiveness.

Tape Lenght vs Cable Size Figure 2
Recommended lead for most applications is 13mm (0.50 in.), although some additional shielding will be achieved when utilizing a 6mm (0.25 in.) lead. The length of EMC Shielding Tape required for each cable using these two types of lead wraps can be obtained by referring to Figure 2.
