MIL-DTL-38999 Series III Connectors

DEUTSCH DTS Series and ACT Series are the standard circular connector for use in harsh military and aerospace environments. High density layouts with up to 187 data connections and power contacts rated up to 23A. They feature a triple-start coupling with anti-decoupling ratchet for high vibration applications, grounded plug for superior EMI shielding and 100% scoop-proof contacts for blind-mate coupling. They are qualified to stringent MIL-DTL-38999 Series III specifications.
