Application process

Any system that use low-intensity signals are vulnerable to electromagnetic interference (motors, relays ...) radio (telephone, TV, radio ...)

The shield can protect low-intensity signals from interference.

Protection levels required. Control parameters:

  • Meshing density (step, angle of attack, number of threads per coil).
  • Cable diameter.
  • Meshing Requirements: compromise between weight and EMI-RFI protection.
  • Type of material for the braid: tinned copper or nickel of 120 microns thick.
  • Textile Nomex Protection.


  • The shielding degree is measured with a Ro meter (measured in Ohms).
  • The application will determine the degree of protection.
  • Shielding measures are complementary to the electrical testing of wiring.
