Overview

Hook-N-Shield® (VNH)
  • VNH-23 jacketing offers rugged component protection
  • SHX-4 shielding mesh provides good EMI protection
  • Velcro® closure allows for quick installation without tools

Hook-N-Shield® (VNH) combines durable jacketing with shielding mesh for component and EMI/RFI shielding protection. The outer jacketing, made from VNH-23 material, is flexible, PVC coated, military grade and flame retardant—ideal for applications in rugged environmental conditions. The inner jacketing has SHX-4 material for highly flexible EMI shielding. 

Hook-N-Shield® (VNH) has a hook-and-loop closure for an easy, no-tools-required installation. This closure type also allows accessibility to the components inside when needed. There is an optional sewn-in braided ground wire for applications with such requirements. The operational temperature range of Hook-N-Shield® (VNH) is -65°F to 171°F (-54°C to 77°C).

ATTENUATION DATA WAS OBTAINED USING MIL-DTL-83528H (MODIFIED). TESTING WAS PERFORMED BY ACCREDITED, THIRD-PARTY EMI LABORATORIES.
