Definitions for "Face seal"
Device which seals by means of axial contact pressure, usually between two surfaces in a plane at right angles to the axis.
(connector) See interfacial seal.
Sealing of a multiple contact connector over the whole area of the interface to provide sealing around each contact. This is usually done by providing a soft insert material on one or both of the connectors which are in compression when mated. This provides an environmental seal between the interface of the plug and the interface of the receptacle and also increases the dielectric between contacts.
