AIR TIGHT CONNECTIONS

There exist several applications where there is a desire to prevent air from penetrating an enclosure. One of these applications is on electronic boxes. In order to prevent a requirement to fill the box with potting, some applications simply put a light conformal coat on the board. Additional protection against oxidation can be achieved by sealing the box against air penetration after it is assembled and tested.A previous barrier to this application was the connector interface.A flange seal does a good j ob of preventing air migration at the flange, but in many designs, air can migrate through the pin terminal area. This air can bring water vapor with it and this vapor can condense on the board.

Deutsch has several designs that offer a seal around the terminal which prevents any air leakage through the connector at up to a 5 p.s.i. pressure differential. This pressure specification covers applications at  all altitude pressure differentials around the world.
