HD38999 Connectors

Amphenol Aerospace HD38999 Connectors offer 30% more contact density than the highest density Mil Spec 38999 connectors of its size. Designed using mil-specified 38999 components, mil-qualified 39029 size 23 contacts, and mil-qualified 38999 insert materials, these connectors are essentially a drop-in replacement for the standard 38999 connector. The design allows the user to increase the number of contacts without increasing the size of their connector. To meet reduced system size requirements, users can select smaller shell sizes without decreasing the number of contacts. Amphenol Aerospace qualified their connectors to the requirements of MIL-DTL-38999 making the HD38999 Connectors well-suited for applications such as avionics, C⁴I, commercial airframe, military vehicles, space, radar for ground and air, and missile and ordinance.
