Overview

VNH-23 jacketing offers rugged component protection
SHX-4 shielding mesh provides good EMI protection
Velcro-style hook-and-loop closure for quick installation

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 Velcro-style 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).

Features

VNH-23 jacketing provides better flexibility and better abrasion resistance
Hook-and-loop closure requires no tools for installation
Operational temperature range of -65°F to 171°F (-54°C to 77°C)

Benefits

Wrap-around solution requires no disassembly or disconnection of components
Flame-retardant, waterproof VNH-23 jacketing for use in rugged environments
SHX-4 (SnCuFe) shielding mesh can withstand harsh conditions

Installation Instructions

FREQUENTLY ASKED QUESTIONS

Q: What lengths of hook & loop jacketing are available?

A: Our hook & loop closed sleeves can be ordered in lengths as short as a few inches to lengths of 100 feet or more. When quoting or ordering, make sure to clearly state the length of each sleeve in inches, which is typically referenced at the end of the part number (-X120.0 for example).

Q: What diameter of jacketing do I need? Is it recommended to oversize?

A: We will often suggest oversizing the sleeve diameter by 1/8” to allow for ease of installation. If the application requires significant bending or flexing we will suggest even more extra room. For assistance with sizing you can also contact one of our design engineers.

Q: Can I cut the Jacketing?

A: Yes*. *We recommend ordering hook & loop closed
jacketing to the exact length required, but you absolutely can trim down a spool of Hook-N-Shield jacketing using standard scissors. When cutting lengths of Hook-N-Shield jacketing, keep in mind the newly trimmed edges will not have the back-stitching found on the factory edges and the stitching may come loose over time. For more details on cutting or size recommendations please contact one of our design engineers.

Q: What is the minimum bend radius of the tubing?

A: There is no minimum bend radius for our Hook-N-Shield products. The flexible jacketing material allows for extreme amounts of bending and flexing. The bend radius of the installed tubing is typically dictated by the harness it is covering.

Q: What is the difference between Hook & Loop and Velcro?

A: “Hook & Loop” refers to the family of closures that utilize small loops of fiber and tiny hooks to interlock and hold material together. Velcro is the name of the company that originally created the hook-and-loop fastening system. Here at ZT we use Velcro brand fasteners as well as fasteners from other brands.
