Electric induction and coupling can cause electromagnetic interference. Therefore, a lot of equipment that has such electrical functions should have a gasket to avoid affecting critical applications such as aerospace electronics, military, medical and vehicular systems. Anyone who intends to buy such a seal should consider a few aspects. The following are guidelines for buying EMI seals to consider.
Confirm whether it can withstand heat. Quite a few applications that lead to electromagnetic interference produce heat. Therefore, they need a gasket that can withstand such temperatures and work perfectly well as well. Make sure that you are familiar with the amount of heat that the device can produce before you decide to buy the seal.
Ensure that it can accommodate pressure. Some applications lead to tension. Such phenomenon requires a reliable gasket that can withstand it. There are varieties of materials that one can use depending on the amount of pressure induced. The best types of seals include the wire mesh types and the copper fingers which release force to the environment.
Determine which stage of manufacture is ideal to use the gasket. Clients who prefer custom-making the seals should consider which manufacture stage is suitable for the product. The best period is during the design since you can leave enough flange to fit the gasket. You can choose different types of mounting starting from clip-on, slot, channel and the pressure sensitive clips.
Ensure that they have a moisture sealing. Most seals with knitted wire mesh or copper fingers cannot protect from dust and moisture. Therefore, they should have protection such as rubber seal required to provide cover from such elements. A conductive fabric can also be an excellent material that protect the device from dust. You can as well use a conductive elastomer.
Confirm whether the seals are compatible with the enclosed material. Galvanization corrosion can happen when there are salt spray and the metal used in the seal, and the enclosed one has different noble states. So, one should use metals that have more or less close galvanization scale to avoid such occurrence. One of the commonly used combinations includes coated silicone elastomer to cover a coated nickel product.
Determine which frequencies you want to shield. Most aerospace and military applications require a shield that can inhibit magnetic waves. Therefore, using a knitted wire mesh or copper fingers can be a perfect match to release the induced current within the guard. For low frequencies, one should use a solid metal while electric can fit in any gasket to their limitation.
Acknowledge the maintenance measures that you should use. The longevity of a gasket relies on the means used to maintain it. Some of the steps that one can use include using an open and closing mechanism that allows you to do necessary maintenance. Besides that, repair the gasket if it wears out. Most people leave the gasket unattended for quite a long time which needs compression stops or collars. The collars or stops will evade the possibility of breaking of the gasket due to pressure.
