Rigorous Qualification Testing Glenair has completed numerous rounds of qualification testing on the Series 806 and has all necessary test reports on file. A comprehensive summary report on Series 806 performance, including operating temperature range, moisture resistance, vibration and shock, and dielectric withstanding voltage is offered here in this issue. But for overview purposes, let’s take a look now at four of the most important qualification benchmarks. High-temperature tolerance in the range of +200°C is a rare capability in micro miniature connectors. High temperature tolerance is critical for the Series 806 Mil- Aero as high-altitude DWV and the placement of the connector in FADEC controls and other areas in close proximity to engines was a primary design requirement. Dielectric insulators are fabricated from high-temperature tolerant, glass-filled rigid dielectric. And unlike many current and legacy military/aerospace connectors, insert retention in the Series 806 is guaranteed through the incorporation of a mechanical retention ring.

For applications requiring even higher temperature tolerance, special ThermaRex and ThermaRex Cryo designs are currently in testing, with expanded temperature tolerance from -200°C to +300°C.

Insert retention ring

 Both the dielectric glass material and the insert retention ring contribute to the improved strength and reliability of Series 806 Mil- Aero connectors in high-temperature environments like aircraft FADECs.
