Compatibility in Electrical Wire Interconnect Systems

Optimizing Material Selection for OPERATING TEMPERATURES

When you absolutely need high temperature technologies with proven electrical performance Many applications demand interconnects that function beyond the usual mil-spec limits of -65°C to 200°C. ThermaRex ™ High-Temperature (HT) connectors are designed to function up to 300°C continuous. Cryogenic connector variants are suitable for applications as cold as -200°C or 73 Kelvin. Two key technologies are utilized: the first being an ultra high- and low-temperature tolerant dielectric material, and the second a unique crown ring contact series, resistant to stress relaxation at high temperatures compared to standard split-tine sockets. 1 Designing interconnects for temperature extremes also depends on suitable wire and cable that can perform with continuous service at 300° C. Most legacy high-temperature wire designs utilize thick insulation made of fiberglass—not suitable for use with high-density aerospace interconnects. Glenair ThermaRex wire is small enough to work with standard wire sealing grommets and back- end accessories, and has been fully tested for continuous service at 300°C. 2 High-temperature wire shielding solutions are also a critical requirement. Traditionally, high temp applications would use Nickel 200 or pure stainless steel braid for shielding—heavy options with only moderate EMI shielding. Glenair ArmorLite ™ CF is a stainless-steel-clad copper microfilament braid with -80°C to 300°C temperature tolerance and outstanding EMI shielding performance. 3
