M I S S I O N - D R I V E N D E S I G N : MIL-DTL-38999 TYPE Micro Miniature Conne c t o r s a nd Ca b l e s
The Series 806 Mil-Aero is a high-density, high- performance micro miniature circular connector ideally suited for harsh military/ aerospace applications.

SHOCK + VIBE The Series 806 Mil-Aero is an aerospace-grade micro miniature circular connector with triple-start threaded coupling. The 806 connector is smaller and lighter than conventional aerospace connectors. Featuring size 22HD and 20HD contacts, plus size 8 power and high-speed El Ochito®, quadrax, and fiber optic options, the Series 806 offers up to twice the number of contacts—with no reduction in performance—compared to MIL-DTL-38999 Series III. In fact, independent laboratory testing has demonstrated that the Series 806 meets, and in many cases exceeds, the requirements of MIL-DTL-38999. Glenair pioneered integral shield banding platforms to allow direct attachment of cable shields, boots, and overmolds. This innovation continues with the 806— Glenair’s first connector to exclusively use the ultra lightweight Nano shield Band-Master ATS band for maximum size and weight reduction.

But there is more to the 806 than just size and weight reduction. This flight-proven high-performance connector has many innovative features that meet the most aggressive requirements of the military/aerospace industry, including better resistance to vibration-induced decoupling. This is accomplished by re-engineering the ratchet mechanism and introducing a shallower mating thread ramp angle than is available in D38999. When it comes to sealing, the Series 806 Mil-Aero connector features an O-ring radial interface sealing design instead of a flat gasket. This allows for easier metal-to-metal coupling for improved sealing, as well as better EMI performance. The MIL-DTL-38999 Series III and other legacy aerospace circular connectors have a flat gasket inside the receptacle shell. This peripheral seal must be compressed sufficiently to allow full metal- to-metal connector bottoming. In certain tolerance conditions this seal can make it difficult to fully mate the connectors “without the use of tools” as is required by MIL-DTL-38999.
