8D Series - MIL-DTL-38999 Series III
Introduction
This product family is in accordance with MIL-DTL-38999 K Serie III , EN 3645 and CECC standard
for bronze shell
Proposed in aluminium, composite, stainless steel, titanium and bronze versions.
This family gives :
• A high contact density up to 1 contacts #22D.
28
• A quick screw coupling with self locking mechanism.
• 100% scoop proof offering polarising options by angular positioning of keys.
• EMI enhanced protection by shielding ring and shell to shell bottoming.
Moreover, composite connectors reach high performance in terms of:
• Resistance to salt spray (> 2000 hours)
• Endurance : (> 1
500 mating / Unmating operations with specific contacts)
Its choice is recommended wherever weight is critical (typically –30% versus aluminium version)
or particularly in harsh climatic and mechanical environments.
8D Titanium version is characterized by a very high and mechanical resistance:
• Weight saving as compared to stainless steel
• Unplated and nickel plated version available
8D / D38999 family has applications in:
• Aeronautics and military
• Marine and offshore
• Industrial.
