Douglas Electrical Components (Deco) has introduced 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 circuits that can be disconnected at the pressure bulkhead or the vacuum port plate, enabling mating and unmating.

Deco manufactures more than 1,000 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 pin-to-socket design.

Another feature offered by the Potcon line is the connector-to-wire configuration, which is available alongside the standard connector-to-connector and connector-to-solder cup designs.

Ed Douglas, president of Deco, said: ‘By providing a mated solution that uses the same connection in the vacuum chamber as on the bench, the Potcon feedthroughs facilitate bench-top testing prior to installation in the vacuum chamber, minimising the risk of project failures that may arise.

‘In vacuum-chamber applications, regular mating and unmating is common and a typical wire harness solution makes that operation very cumbersome.

‘With the Potcon connectors, customers can do dry-run testing through the same connections without having the vacuum bulkhead present.

‘This also saves undue wear on the actual installed wiring into the chamber, which can stay intact,’ he added.

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 Mil-C-series, circular-plastic, sub-D (including standard density and micro-D), coaxial, waterproof, thermocouple, high-current and high-voltage connectors.

Potcon feedthroughs are 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^-10sccm He/s, electrical hi-pot tests up to 30KV and electrical continuity.
