Souriau-Sunbank micro38999 Series (8DA, 8LTA & 8BA)


The Souriau-Sunbank micro38999 series is a miniature circular connector derived from MIL-DTL-38999 design and available in three coupling systems: threaded, break away and bayonet.

50% shorter length, 33% smaller diameter and 3 times lighter, Souriau-Sunbank micro38999 connectors are ideally suited for applications with space and weight constraints such as defense applications (display, UAV, helmet, tactical radio) and industrial applications (remote control, drilling, medical, instrumentation, etc.).

The Souriau-Sunbankmicro38999 series is the first complete platform on the market of integrated backshell products available with a 38999 design and is compliant with the harshest specification (high vibration, operating temperature, durability, corrosion resistance, EMI shielding, etc.)

Three coupling systems available to choose the best compromise for your application:

  • Threaded coupling (8DA range): high vibration withstanding and strong signal protection.
  • Break away (8BA range): quickest mating/unmating cycle for applications where reactivity is key.
  • Bayonet (8LTA range): tightest space requirements with reliable mating.

The electrical crimp contacts can be removed, enabling users to wire and unwire micro38999 connectors directly on site. The contacts have a M39029-based design providing a high-quality secure connection.

Souriau-Sunbank micro38999 connectors offer concrete RoHS alternative to cadmium with black zinc nickel, nickel and stainless steel. Souriau-Sunbank Connection Technologies – SOURIAU has more than 10 years of experience in producing Zn Ni with continuous improvements to comply with military and aerospace harsh environment conditions. Our Zn Ni connectors are the first one to be qualified by US Defense standards organization (DLA Land and Maritime).
