ROSEMEAD, CA— Recent aerospace developments have driven the need for instruments and systems to perform in extreme environments at temperatures not previously specified, especially in commercial jet engine applications.

Hermetic Seal Corporation, a unit of AMETEK Interconnect Technologies and a leader in hermetically sealed connectors for extreme environments, 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 -65oC to 440oC (-85oF to 824oF) it maintains its hermetic integrity at an unparelleled 1x10-9 cc/sec of helium at 15 PSI leak rate and an insulation resistance value greater than 500 megaohms@500 VDC. At 426oC (800oF), the HTX connector has an insulation resistance value greater than 1,000 megaohms@500 VDC.

The current generation of hermetically sealed electrical connectors used by the aerospace industry operate reliably in the -65oC to 260oC (-85oF to 500oF) temperature range with a leak rate of 1x10-7 leak rate and an insulation resistance value of 1,000 megaohms at 500 VDC. However, when subjected to higher temperatures not only does the liklihood of a hermetic seal failure increase but the resistance value of the glass insulator also declines.

These factors result in significantly limiting the functionality of many instruments and motion control devices in high-temperature environments.

The new HTX connector 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.

Founded in 1945, Hermetic Seal Corporation was a pioneer in the development of glass-to-metal seal technology. Today, as a unit of AMETEK Interconnect Technologies, Hemetic Seal Corporation is the largest independent producer of hermetically sealed connectors for extreme environments, such as those found in oil and gas, aerospace, medical and other industries.

AMETEK Interconnect Technologies (www.ametekinterconnect.com) is a global leader in highly engineered hermetic interconnects, custom glass-to-metal-sealed connectors, and high-temperature, high-pressure bulkheads and a unit of AMETEK, Inc., a leading global manufacturer of electronic instruments and electromechanical devices with annual sales of more than $4.2 billion.
