Understanding Oriented Wire Shielding and how it Works

EMI and Shielding is rather important for containing and working with electromagnetic fields. The shields work by blocking the magnetic field with conductive or magnetic barriers. Shielding gaskets are designed to be in enclosed spaces, which will allow it to isolate the electronic devices from nonelectric device­s. EMI shielding differs from RFI shielding. RF shielding is responsible for dealing with radio waves, where as an EMI shield deals with electromagnetic and electrostatic fields. Shields can be made in different ways with different materials. This creates different results from each shield. This allows for better shielding and output.

Wire Oriented Silicone Gaskets are a specific type of shield. It is technically called a composite gasket. It is used to suppress both RFI and EMI. One of the clear benefits of an oriented wire shield is its ability to give effective and full pressure environmental seals (between mating surfaces). The product is made with conductive wires that are placed perpendicularly with the mating surface (or embedded in a sponge when applicable). Most commonly, the military and commercial applications, ones that deal with heavy doses of EMI and RFI, utilize oriented wire shields

Another big perk of using oriented silicone gaskets is its ability to function properly in extreme environments. Because the shield works with a metal-to-metal conductive path, it can operate in extreme temperatures. The range of temperature usage for this sort of shield is roughly from -65 degree Celsius to 200 degrees Celsius. Not only are these shields durable under extreme temperatures, but also they are also resistant to water (not water proof, meaning you wouldn't want to submerge your shield). If you are working outdoors, you do not have to worry when it starts to rain or drizzle.

You can acquire this sort of shield in three different types: strip, ring, or sheet form. Each type of material operates and functions differently. Calling a local EMI/RFI shielding company will allow you to fully talk through your wants and needs.
Customized oriented wire shielding is available. Shields need to be built specifically for an industry, function, and product. This requires shielding at different lengths and thicknesses. You also must identify the type of silicone and adhesive products being used because these two things directly affect the temperature range. Solid silicone can get hotter and colder than sponge silicone.

These decisions are difficult to make alone, so reach out to a local EMI/RFI company today.
