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.
Consider whether it accommodates pressure. Another common occurrence in electric induced or coupled material is pressure. Such element needs control by adopting a device that can withstand it. The ideal application involves the use of a wire mesh seal which will reduce pressure inside the device by releasing it to the surrounding. If you intend to use solid metal, ensure that it has a high-pressure capacity and the right mechanism to hold it down.
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.
Confirm the amount of frequency that you will shield. Applications in aerospace and military might produce a lot of magnetic waves. Therefore, you have to look for a shield that can prevent the magnetic waves depending on their frequency. The best type of buffers to include the copper fingers or the knitted wire mesh which release the current created within the shields. If the rates are quite low, you have to look for solid protection other than the open one.
Learn how to maintain the seals. The gaskets tend to wear out with time. Therefore, one has to acknowledge various ways to preserve the longevity of these products. The right way includes regular maintenance and using compression collars and stops. The compression collars are quite useful since they reduce breaking in case of too much pressure.
