ABSTRACT:
A cost efficient electrical feedthrough is provided for forming a hermetic seal with a container and allowing a desired number of inputs to be connected between varied environmental conditions. The electrical feedthrough can be employed for environmental conditions including high pressures, high temperatures, low temperatures and the presence of corrosive gases. A first wire situated in a first environmental condition and a second wire situated in a second environmental condition are connected via a conducting material. The first environmental condition and the second environmental condition are separated by a divider having an opening for passing therethrough either the first wire or the second wire. A first seal extends from the divider to a material in contact with the conducting material. In an aspect, a second seal forms an enclosed area with the conducting material for surrounding a wire engaging hole and any wire extended therethrough and sealing the first environmental condition from the second environmental condition.
