Fabric over Foam Gaskets for EMI Shielding: What You Need to Know

Fabric shielding gaskets, especially the fabric-over-foam variety, are extremely effective in protecting electronic devices from electromagnetic interference (EMI). Made from fiber cloth (usually nylon yarn or synthetic polyester) and the fabric covered with nickel and copper, these gaskets are conductive and resistant to abrasion. They use polyurethane-made foam core and are easy to configure. The mix of nickel and copper reduces the harmful effects of EMI. Flawless designing and affordable materials make these gaskets suitable for use in many industries. Read this article to learn more about these gaskets for eliminating unwanted interference.

Design and Shape

Most of these gaskets come with a cellular structure, and their design makes it simpler to slide them via the spaces for easy installation. EMI shielding product suppliers develop a range of fabric-over-foam gaskets to meet your specificshielding needs.Quality gaskets come in L, D, U, and P-shapes. The nature of the design is effective in removing unwanted radiations, thus protecting your expensive electronic devices, appliances, and equipment. Pick from a wide range of design, thickness, and shape to meet your shielding needs. Based on theirshape and material, gaskets can have a compression between 30 and 75 percent. This facilitates material system tolerance. Reputed suppliers design custom shapes and sizes to meet specific application needs together with pressure-sensitive adhesives.

Application Use

You can choose from EMI gaskets for applications with reduced compression force. With a plethora of features and advantages, shielding gaskets have application use in the automobile, telecom, military, and consumer electronics sectors. An easy-to-customize structure, lightweight nature, and resistivity to abrasionare a few of the properties you can rely on while opting for shielding products. Panel gaskets, IO gaskets and connector, digital cameras, computer servers, external and internal hard drives, cabinet doors, card cage gaskets, telecom enclosure cabinets, and printers are a few of the applications where fabric over foam gaskets produce optimal results.

Benefits

Besides EMI attenuation, there are multiple benefits of fabric-over-foam gaskets. These include the availability of copper and nickel in the fiber knit, 65 dB to 80 dB EMI shielding performance, low resistance for increased conductivity, and more durability. The other advantages are:

• Compatibility with diverse host materials.
• Custom shapes.
• Varied Designsand configurations.
• Optimizedperformance.
• No environmental degradation.
• Low compression, simple installation.
• Performanceeven within a temperature range of minus 40 degrees Fahrenheit to 158 degrees Fahrenheit.

Ease of Use

Though EMI shielding gaskets have many benefits, they perform best in a controlled environment. As sensitive equipment or machinery works under controlled conditions, you don’t needto spend exorbitantly on shielding materials. Even if a piece of machinerydoes not requirespecific temperature conditions to operate efficiently, it is worth building a controlled ambiance and use fabric gaskets to protect your equipment from interference.

Choose quality fabric-over-foam shielding gaskets for maximum EMI protection. If you want more information about these products, features, or benefits, consult with a reputed gasket supplier. Make an informed decision before you opt for a product.
