38999 Connectors in Brief
The MIL-DTL-38999 connector ranges (originally MIL-C-38999) are a family of high-performance circular connectors originally designed to meet the needs of the Military and the Aerospace Industry, but which are now also used in many commercial applications where high performance and complete connector reliability is essential.
MIL-DTL-38999 Series I (8LT)
MIL-DTL-38999 Series I from Souriau is a sub-miniature bayonet coupling, aluminium circular connector with high contact density & rear release crimp contacts. Good for harsh environments & 100% scoop-proof, the MIL-DTL-38999 Series I connector remains the perfect connector for most general purpose applications.
MIL-DTL-38999 Series III (8D)
MIL-DTL-38999 Series III is designed to provide extremely high performance capabilities. Available in Aluminium, Stainless Steel, Composite & JVS (Marine) Bronze shells, the 38999 Series III connector range is ideal for severe environmental use as well as being the perfect general purpose 38999 series connector. The improved quick screw coupling system, rear release crimp contacts and increased shock resistance, make the 38999 Series III connector, the connector of choice for many users.
MIL-DTL-38999 Series Derivatives
The MIL-DTL-38999 Series III connector range also includes derivatives for:
Power: 38999 connectors with maximum Current ratings of: 45, 80, 250, 400, 600 and 750 amps.

All of the above 38999 derivatives are mounted in MIL-DTL-38999 Series III housings and are available in Composite, Aluminium, Marine Bronze & Stainless Steel/Firewall Shells.
Micro 38999
The micro38999 series is smaller and more compact than D38999, but retains all the technical features and excellence required by the Military and the Aerospace industry. The micro38999 miniature range is made to meet a new generation of defence and industrial applications where space and weight are limited.
