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.
Confirm when to design the seal. Custom-made gaskets have high chances of offering the appropriate service. Even so, you should acknowledge the best manufacture stage to design and manufacture the seal to get the best result. The best step is the designing phase where the manufacturer can leave enough flange to fix the gasket. It also provides flexibility in the choice of mounting to use.
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.
Consider compatibility. Compatibility depends on the galvanization corrosion of the respective material. Therefore, you should look for metals that have similar galvanization scale. For instance, you can rely on a coated nickel to enclose a silicone elastomer in a graphite coat. The galvanization process results from the presence of salt spray. It can significantly break down the conductive joints.
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.
