Hermetic Seal Corporation’s HTX Connector for Aerospace

By News Release | February 09, 2015

The Hermetic Seal Corporation’s HTX connector for aerospace applications performs in temperatures ranging from -65°C to +440°C.

Hermetic Seal CorporationAmetek Hermetic Seal HTX Connector for Aerospace, a unit of AMETEK Interconnect Technologies, has developed interconnection technology that meets the increasingly stringent temperature range and leak rates required for even the most highly demanding aerospace applications.

The new HTX connector not only performs in temperatures ranging from -65°C to +440°C (-85°F to +824°F), but it maintains its hermetic integrity at an unparelleled 1×10-9cc/sec of helium at 15 PSI leak rate and an insulation resistance value greater than 500 megaohms at 500VDC. At +426°C (800°F), the HTX connector has an insulation resistance value greater than 1,000 megaohms at 500VDC.

The current generation of hermetically sealed electrical connectors used by the aerospace industry operates reliably in the -65°C to +260°C (-85°F to +500°F) temperature range with a 1×10-7 leak rate and an insulation resistance value of 1,000 megaohms at 500VDC. However, when subjected to higher temperatures, not only does the likelihood of a hermetic seal failure increase, but the resistance value of the glass insulator also declines. These factors significantly limit the functionality of many instruments and motion control devices in high-temperature environments.

The new HTX connector for aerospace applications utilizes a proprietary glass insulation material that was developed by Hermetic Seal Corporation. This technology enables full electrical functionality in the hermetic receptacle welded to a high-temperature instrument or device as well as the cable-terminated plug with which it mates.

In addition, the HTX connector series is available in shells and insert arrangements that meet the dimensional requirements of several MIL specifications.
