For a perfect seal
WISA connectors distinguish themselves from other connectors. They have, in addition to two support rings, an inwardly folded flap. This flap ensures a perfect seal because the contact area is much larger than only of support rings.
The connectors are made of a very flexible plastic. The material has a very long life and is highly reliable.
The connectors have proven to be able to handle the dimensional tolerances of the ceramic particularly well because of these properties and therefore combines fast assembly with great operational reliability.
The WISA connector is a quality product that should not be absent from your work.
