Lightweight low resistance hermetic connectors offer a cost-effective option

Powell Electronics now offers lightweight and low resistance CODE RED hermetic connectors from Glenair. The products are lightweight, feature low electrical resistance, cost-effective and meet NASA outgassing conditions as well as aerospace temperature and corrosion resistance standards.

CODE RED is an innovative sealing encapsulant and application process that was invented by Glenair. It offers durable hermetic sealing in a lightweight aluminium package. Glass to metal hermetic sealing has traditionally been employed in the aerospace and petrochemical industries due to the strength and long-term endurance of the materials. But glass-to-metal seal hermetics are far heavier, more expensive and have high electrical resistance.

Cost-effective hermetic connectors provide full hermetic sealing, better than 1X10-7 in a lightweight aluminium shell (weight saving of up to 50% compared with glass-to-metal seal hermetics) with low electrical resistance gold-plated copper contacts. The use of conventional gold-plated copper alloy contacts notably increases the electrical performance.

These connectors are available in Glenair SuperNine (D38999 Series III type metal and composite), Series 80 Mighty Mouse, and M24308 D-Sub connector ranges. Special non-magnetic (zero residual magnetism) versions are also offered. The operating temperature range is -65C up to +200C.
