Protecting cables against electromagnetic interference: EMI sheaths Protecting cables against electromagnetic interference: EMI sheaths


EMI (ElectroMagnetic Interference) protective sleeves shield cables from interferences generated by nearby cables. By directing these disturbances to the ground, they ensure continuity and reliability of device operation.

HellermannTyton’s EMI sleeves are made from a unique combination of tinned copper and polyester. This combination provides effective shielding while maintaining flexibility and high abrasion resistance. These braided sleeves easily adapt to angles without pinching or breaking, ensuring durable installation even in complex configurations. They are essential in various industries:

  • Railway
  • Automotive (especially for electric vehicles)
  • Shipbuilding
  • Defense
  • Any industry with devices sensitive to interferences
