    L-shaped gasket 7500 series
    L-shaped EMI/RFI shielding gasket with water seal (IP seal) for thin doors and lids

    Holland shielding systems B.V. has developed this L-shaped gasket to make an efficient combined seal for doors and lids. This L-shaped gasket is used to achieve two goals at once. A water seal and an EMI seal.

    This L-shaped gasket is made from a whole piece of neoprene foam. One side has been laminated with conductive textile (the conductive side) and the other side is blank neoprene that 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 electrical conductive part on the other side of the gasket makes an electrical connection between the door and the leaf of the door.

    In the above picture you will see a closed lid with the gasket mounted on the inside of the lid. Please see the video to right side for more information.

    The gasket will realize a perfect airtight locking and makes at the same time an electrical contact on the inside of the housing. The electrical contact is free of water and dust.
