38999 Series III: 8D Series
Since the early 80’s, Souriau is a major supplier of 38999 Series III, the screw-coupled
version of MIL-C-38999. Present on the main international programs, Souriau has
developed a range of products that meet the performance required in extreme
environments:
• Civil and military aeronautics
• Ground military
• Industrial
• Marine and offshore
This evolution of MIL-C-38999 allows:
• A high contact density up to 1
28 contacts #22D
• A quick screw coupling with self locking mechanism
• High resistance to harsh environments (vibration, 200°C)
Always at the cutting edge of innovation, Souriau’s teams have continuously improved
this range of connectors:
• Composite version in the 90’s (Its choice is recommended wherever weight is critical)
• Titanium version for weight saving and very high and mechanical resistance
• Today Souriau remains innovative with cadmium free and RoHS solutions.
In 2009 Souriau was the first to be QPL qualified for Zinc Nickel plating.
This product family is in accordance with MIL-DTL-38999 Series III, EN 3645, CECC
(standard for bronze shell), ... and also meets many customers’ standards (Rolls Royce,
ABS, BACC, ...)
