## **KNITTED WIRE MESH** 

## **Knitted Wire Mesh** 

## Overview 

Kemtron Limited (Kemtron), now part of TE Connectivity, manufactures a range of knitted wire mesh products, providing a costeffective solution to high shielding performance applications in both the magnetic and electrical fields. 

These products are manufactured on a circular wire knitting machine using a single wire. The mono-filament interlocking-loop construction gives strength while allowing it to conform to almost any size or shape. The range of solid knitted wire mesh products are not suitable in applications that require regular opening and closing. If you require this feature please look at products with a sponge elastomer core. 

Solid knitted mesh products provide an excellent radio frequency interference (RFI)/electromagnetic interference (EMI) shield between two metallic surfaces. A range of wire types is available to allow for good galvanic compatibility thereby reducing or limiting the possibility of corrosion. 

## Kemtron’s knitted wire mesh 

## is available in 2 options 

- Solid Knitted Wire Mesh 

- Elastomer Cored Knitted Wire Mesh

## Production Capabilities 

Kemtron has developed its knitted wire mesh production facility and expertise in this area to enable it to produce RFI/EMI gaskets in a wide range of materials and in many different size configurations. Together with our extensive fabrication capabilities and large stocks of raw materials, we can manufacture knitted wire mesh gaskets to suit many applications that support electromagnetic pulse (EMP) survivability. 

We offer a bespoke service, which can also produce economical gaskets, with good delivery times, in prototype quantities or for short, medium or large commercial production runs.

## **Solid Knitted Wire Mesh** 

## Product Overview 

The product consists of a knitted wire that is formed into an all wire profile forming a continuous gasket strip. 

## Application 

Solid knitted mesh gaskets provide an excellent RFI/EMI gasket shield between two metallic surfaces and with the choice of wire mesh material available allows for a good galvanic match with mating flanges, thereby limiting the possibility of corrosion between gasket and flange. 

- RFI/EMI applications 

- Panel seals in screened rooms 

- Areas with infrequent access 

- Cable Shielding (Wrapping with flat bandage) 

## Availability 

- In continuous lengths, cut to length in continuous lengths or cut to length 

- Variety of profiles and sizes available 

- Self adhesive backing is not recommended with this version of mesh 

## Design Considerations 

- Consideration should be given to the termination of cut mesh ends. Sometimes loose wires are evident after cutting. If you choose to cut the mesh yourself loose wires can be avoided by: 

- Dipping the end in glue 

- Spot welding the cut end 

- Sewing the cut end 

- Sufficient compression forces are required to achieve good contact. Contact seal between the metalwork 

- Galvanic compatibility can be achieved by choosing a suitable wire type 

- Water and moisture sealing is not possible with this product. However it does offer a limited dust seal 

- Solid knitted wire mesh suffers from compression set. So it is not recommended for frequent opening of panels. If you require this feature, refer to the knitted wire mesh over an elastomer core section

## **Knitted Wire Mesh** 

## Product Overview 

This product is a knitted wire mesh over an elastomer core such as silicone cellular profile. Usually this consists of 2 layers of knitting over the elastomer core. The knitted mesh is then formed into the selected profile making a continuous gasket strip which is flexible and compressible and which makes an excellent RFI/EMI gasket. 

## Application 

In addition to making an excellent EMI/RFI shield between two metallic surfaces the choice of wire mesh material available also allows for a good galvanic match with mating flanges, thereby limiting the possibility of corrosion between gasket and flange. Further, the elastomer core of the gasket allows it to be compressed using low to medium force conforming to uneven surfaces and recovering well after use. 

- Groove gaskets such as O-rings 

- Due to its resiliency and low compression force, ideal for use in situations where repeated opening and closing operations are necessary 

## Availability 

- In continuous lengths 

- Cut to length 

- Variety of profiles and sizes 

- Selection of wire to meet galvanic compatibility requirements 

- A selection of elastomer cores are available to meet conditions such as temperature range, compression set, compression force 

- Self adhesive backing is not recommended with this type of product 

## Design Considerations 

- Consideration should be given to the termination of cut mesh ends. Sometimes loose wires are evident after cutting. If you choose to cut the mesh yourself loose wires can be avoided by: 

- Dipping the end in glue 

- Spot welding the cut end 

- Sewing the cut end 

- Compression forces required to allow good contact. Also the rigidity of the host metalwork 

- Galvanic compatibility can be achieved by choosing a suitable wire type 

- Water and moisture sealing is not possible with this product. However, it does offer a limited dust seal
