EMI shielding gaskets for military electronics are used in everything from touchscreens to targeting systems. To prevent electromagnetic interference (EMI) from disrupting electronic equipment, Elasto Proxy custom-fabricates EMI shielding gaskets from particle-filled silicones. These specialized materials combine the materials properties of silicone rubber with the electrical properties of metal. Elasto Proxy uses waterjet cutting to convert shielding silicones, and bonds cut lengths with conductive adhesives.
EMI gaskets from Elasto Proxy meet the requirements of MIL-DTL-83528, a U.S. Defense Logistics Agency (DLA) specification for electrically-conductive elastomeric shielding gaskets. MIL-DTL-83528 establishes minimum shielding effectiveness levels for various material types over a frequency range of 20 MHz to 10 GHz. MIL-DTL-83528 also specifies hardness or durometer (Shore A) measurements for shielding silicones that are categorized as low, medium, or high durometer. Continue reading
