MAJR Grounding Washers

Electromagnetic Interference / Radio Frequency Interference (EMI/RFI) Shielding Washers

EMI/RFI grounding washers are manufactured from knitted wire mesh stocking that is formed into a resilient metal washer by compressing in a close-tolerance forming die. The grounding washer can be supplied in various diameters and thicknesses to satisfy the many requirements.

By varying the weight of the stocking mesh inserted into the compression die, the density of the washers can be varied, thus increasing or decreasing unit resilience, depending on the needs of the specific application. Washers with a metal density of 15 to 20 percent will "flow" under compression and thus will fill a gap or seam under minimal pressure (10 psi).

• EMI Grounding Washers are all-metallic construction and can be supplied in varying alloys makes them especially effective in hostile environments of temperature or chemicals.

• Resiliency: Grounding washers, when designed into applications that require recovery after the unit has been deflected, can be supplied in a resiliency that will return to 90 to 95 percent of free height after deflection of 25 percent.

• Multiple Applications: The compact construction of the metallic grounding washer makes the unit suitable for applications where the unit is in compression, rotating or sheer, without degrading the effectiveness of unit conductivity.

• All Metallic Construction: For applications requiring grounding where the temperature and chemical environments are extreme, MAJR can supply grounding washers in a variety of wire types.
