L-shaped gasket 7500 series
L-shaped EMI/RFI-shielding gasket with water seal (IP seal) for thin doors and lids
L-shaped gasket 7500 series
Holland Shielding Systems B.V. has developed this L-shaped gasket as an efficient combined seal for doors and lids. The L-shaped gasket is used to achieve two goals at the same time: a water seal and an EMI seal.
This L-shaped gasket is made from a solid piece of neoprene foam. One side has been laminated with conductive textile (the conductive side) and the other side is uncovered neoprene which provides a water seal.
The flange of the door will compress the water-seal side of the gasket with very little force to assure a watertight seal.
The electrically conductive part on the other side of the gasket establishes an electrical connection between the door frame and the leaf of the door.
The picture above shows a closed lid with the gasket mounted on the inside of the lid. Please see the video to the right for more information.
The gasket creates a perfectly airtight closure and at the same time it makes electrical contact on the inside of the housing. The electrical contact remains free of water and dust.
The gasket can be supplied in virtually any size.
Please specify the size you are looking for by email, or use the contact form on the left side of this webpage.
In the picture above you can see how the gasket can be mounted on the inside of the lid. The L-shaped EMI / RFI-shielding gasket can be mounted with a self-adhesive that can optionally be conductive.
When the lid is closed, the electrical contact is shielded from water and dust.
