Z-Shield® (3250) is a wrap around EMI shielded jacket made of fire-retardant Polyurethane film, Z-3250-CN EMI shielding cloth, and an adhesive closure. This combination provides excellent electromagnetic shielding of wires and cables in applications requiring outstanding flexibility, flame retardant and good dielectric strength. Extremely useful in electronics applications where space may require a thin and flexible shielding.

Z-Shield® (3250) can be configured to fit most Round, Flat or Rectangular cable configurations and is available with or without a drain wire installed.

This product has an operational temperature range of -45° to 80°C (-49° to 176°F).


  • Easy to install adhesive closure, requires no tools
  • RoHS compliant


  • Product provides shield coverage > 98%
