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
