Overview

Zipper-Shield™ (VNH)
  • Shielding fabric provides exceptional protection from EMI, RFI, and EMF
  • Zipper closure allows for quick application and re-entry
  • Durable, military-grade jacketing for tough environments

Zipper-Shield™ (VNH) offers a quick and easy solution to shielding from EMI. The VNH-23 is a 0.023” thick nylon fabric coated with a flame-retardant PVC compound. The jacketing is military grade with meeting Mil-C-20696, Type II, Class 2. The flexible yet durable fabric is ideal for rugged conditions with having excellent abrasion resistance and exceptional low temperature performance. The VNH-23 jacketing is also available in either black or yellow coloring.

The Z-3250 is a nickel over copper-plated polyester taffeta cloth that is thin and lightweight. The shielding cloth is flexible yet strong, and has excellent corrosion resistance as well as resistance to environmental deterioration. With having shielding coverage of approximately 98%, the Z-3250 cloth is an excellent choice for protecting against EMI, RFI, and EMF. The molded, plastic zipper closure is ideal for applications needing quick access to wires and cables inside. The zipper is available in black and 5mm or 10mm tooth sizes. Zipper-Shield™ (VNH) also has an optional 15 AWG braided wire for grounding. The jacketing, shielding fabric, and zipper are combined together with a black nylon thread.

Zipper-Shield™ (VNH) is offered for diameters ranging from 0.5” to 4” with custom sizes available upon request, and has an operational temperature range of -40°F to 171°F (-40°C to 77°C).
