• EMI Shielding & Environmental Seal

EMI Shielding Twinseal Gaskets

Twinseal gaskets provide an efficient environmental seal in addition to the EMI shielding from the attached mesh gasket. The mesh gasket is typically supplied in a rectangular profile and is available in all the standard materials and configurations found here. The environmental seal is available in either neoprene or silicone and can be produced with double-sided pressure sensitive tape for stick-on mounting or thru holes for fasteners. Picture frame configurations can be specified as a custom part with the environmental seal bonded at the corners. Click to Order Sample of this Shielding Product.

Design Guide for Custom Parts

1. Accurate steel rule dies are used for cutting the environmental seal. Accuracy of the finished part is influenced by the softness of the material.

2. Linear tolerances for sponge materials are ± 0.031 in. and ± 0.016 in. for solid per 6 in. run.

3. Position tolerances for hole locations are ± 0.016 in.

4. Minimum distance between any cutouts and environmental seal edge should be equal to the material thickness.

5. Minimum hole diameter should be equal to the material thickness.

6. Compression stops to prevent over compression of the gasket can be specified. Compression stops are available in sheet metal gauges. See Fig. 2.

7. Environmental seal dimensions A and B and mesh gasket dimensions C and D must be included in the specification for custom parts.
