MIL-DTL 38999 Series

MIL-DTL-38999 (formerly MIL-C-38999) describes four series of miniature, electrical connectors. The connectors are intended for use as follows: Series I connectors are used where a quick disconnect coupling system is required for blind mating or other mating problem areas, and these connectors provide high-vibration characteristics and are suitable for severe wind and moisture problem (SWAMP) areas with proper connector accessories; Series II connectors are used where the connector is not subjected to high vibration or SWAMP areas and where space or weight is at a premium due to their lower profile; Series III connectors are suitable for blind mating areas, and provide high-vibration characteristics at elevated temperature and are suitable for SWAMP areas with the proper connector accessories; and Series IV connectors are used where a quick disconnect coupling system is required for blind mating or other mating problem areas, and these connectors provide high-vibration characteristics and are suitable for SWAMP areas with the proper connector accessories.
