Hermetic Feedthroughs Allow Interchangeability

Douglas Electrical Components, Inc. introduces its PotCon line of hermetic feedthroughs, which incorporate standard connectors and/or wire harnesses in a single, fully-sealed housing. The PotCon product family features disconnectable circuits at the pressure bulkhead or vacuum port plate, allowing easy mating and unmating.

DECo manufactures over one thousand different varieties of PotCon connectors for vacuum, pressure and environmental containment. These feedthroughs are capable of the standard pin-to-pin or socket-to-socket configurations, but also offer a unique pin-to-socket design. This feature allows for easy bench top testing. Another unique feature offered by the PotCon line is the connector-to-wire configuration, which is available in addition to standard connector-to-connector and connector-to-solder cup designs.

PotCon feedthroughs may be specified and sealed to the housing for reliable mounting. The sealing technology employed allows customers to specify virtually any connector from any manufacturer and have it sealed in either a custom or standard fitting of their choosing. Pre-tested, vacuum outgassed and ready to install, PotCon solutions can seal a variety of connectors, including Mil-C series, circular plastic, sub-D (including standard density and micro-D), coaxial, waterproof, thermocouple, high-current and high-voltage.

PotCon feedthroughs are most often used in space simulation, semiconductor manufacturing and glovebox applications. Testing conducted on these feedthroughs and optional mating connector/cable sets includes Helium Mass Spectrometry Leak Detection to an allowable leak rate of 1.0 x 10^-10 sccm He/second, electrical hi-pot tests up to 30KV and electrical continuity.
