Series Five Lightweight Military Circular Connectors

The MIL-DTL-38999 series of connectors was born in the 1960’s to provide a ruggedized military solution featuring smaller contacts and higher density insert patterns than the already popular MIL-DTL-5015. In the decades since, D38999 connectors have increased in popularity and have become the standard in Mil-Spec connectors for military and aerospace applications.

Along the way, continuous evolution has brought about new shell styles, new coupling methods, new derivatives, and new capabilities, all while remaining as popular as ever.  Amphenol’s new Series Five connector is the next evolutionary step in that impressive lineage, combining all of the capabilities of the traditional 38999 style connector in a lighter, smaller, and more compact package to support the aerospace industry’s ever-changing demands.
