  • Non Flammable

SHX-4 (SnCuFe) is a flexible 4 layer knitted wire mesh EMI shielding material that is made of Tin plated, Copper clad Steel wire. The knitted mesh design creates a highly flexible shield that unlike many tubular braids will not change attenuation performance when articulated. The knitted wire mesh maintains constant window spacing during cable assembly movement and as a result yields excellent EMI shielding performance from 500 KHz through 1 GHz. The material is highly conductive, rugged and is ideal for airborne applications where lightning strike grounding is required. The mesh can be added to most Zippertubing® jacket materials to create an easy to install Zip-On EMI shielded assembly. SHX-4 shields come with a standard 15 AWG drain wire attached to simplify grounding.
