MD801 Series Mil-Spec Qualified Circular Connectors

Cinch Connectivity Solutions miniature circular connectors, equivalent to MIL-DTL-38999 Series III, are designed for space- and weight-constrained aerospace and military applications. Dual-start ACME thread coupling prevents cross-mating and provides fast engagement. They are available with crimp, solder cup, or PC tail contacts in shell sizes 5 to 13, supporting up to 37 contacts. They offer IP67 sealed EMI shielding to 55 dB and an operating temperature range of -65°C to +175°C for 2,000 mating cycles. Cinch has expanded the mil/aero circulars MD801 series to include models available in several finishes, including OD/cadmium and electroless nickel. The connectors are available as plugs or receptacles with standard crimp, solder, and PC tail terminations for board-mount applications.
