Zipper-Mesh (VNH)

SHX-4 EMI Shield, VNH-23 Jacket, Zipper Closure

Zipper-Mesh™ (VNH) cable shielding is a convenient and efficient method of providing EMI/EMP protection to harnesses and wire bundles. It is a highly-flexible shield constructed of 4-ply knitted wire mesh utilizing an internal shield overlap, an integral grounding strap, and a heavy duty zipper closure. The zipper closure mechanism allows installation to be "tool-free", and re-entry to be very simple for cable repair or modification. The Mesh jacket is protected by a rugged, Mil-Spec, PVC jacket of flame retardant VNH-23.
