Ultra soft twin shield 7800 series
EMI/RFI shielding gasket with low closure force to prevent bending of doors, lids and panels combined with a environmental seal (dust/waterseal)

Ultra soft twin shield 7800 series is a combined HF gasket / water seal with very low closure force. All gaskets are provided with a self-adhesive strip on the water seal side.

Ultra Soft Twin Shield 7800 series consists of an HF gasket (compare Ultra Soft Shield 7400) combined with an environmental seal of closed-cell foam rubber.

The standard material for the water seal is neoprene foam. As an alternative a slowly recovering PVC foam, which is fully watertight at 30% compression is available.

Shielding performance

Shielding effectiveness depends on surface, shape of gasket and material used.
