Holland shielding systems B.V. have 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 (the conductive side) and the other side is blank neoprene that is provides a water seal.
The flange of the door will compress the water seal side of the gasket with very little force to realize 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 on the 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.
The gasket can be supplied in every size. Please specify the size that you are looking for by e-mail or use the question form on the left of this webpage.
In the picture above you can see how the gasket is mounted on the inside of the lid. The gasket can be mounted with an adhesive or an conductive self adhesive.
When the lid is closed the electrical contact is free of water and dust.
Benefits
Bends easily around sharp corners without interrupting the water seal.
Excellent water sealing up to IP65 (depending on construction).
Easy mounted with a self-adhesive strip.
Easy to use with small doors and lids.
Low closure force to prefent bending of doors and lids
