Weatherizing EMI Shielding and RFI Shielding

How do you deal with design complications that result from the elements and weather? One of your best choices for a variety of different applications is EMI shielded combo strip gaskets. Combining EMI shielding and weather gaskets allows for engineers to produce electronics that are highly resilient. This shielding option is typically constructed from knitted wire mesh with elastomers integrated into the design for weather sealing. You can commonly find EMI shielding combo strip gaskets in these applications:

• Electronics Cabinet Doors
• Wing Panel Gaskets (protection from lightning strikes)
• Telecommunication Trailers
• EMP Specified Requirements
• Sealing of Shipboard

You have five main considerations to make when working with EMI shielding and RFI shielding that can withstand harsh weather. These include:

1. There are several material options available, which include silicone sponge, neoprene, and more. The most important consideration to make for elastomer types are temperature requirements, fluid exposure, and compression characteristics.
2. You have options for metal alloys. A broad range of metal is used because of the growing demands of galvanic and electrical corrosion. Budgetary needs are the main consideration when choosing a metal alloy.
3. There is a variety of mesh knit layers that are available. Make sure to choose a mesh knit layer based on your required electrical performance. Doing this ensures EMI shielding and RFI shielding is working at peak performance.
4. Combo strip gaskets come as both overmolded and bonded. Overmolded gaskets are typically used in wing panel applications.
