Meterland I MIL-C-38999 Circular Connectors

MIL-DTL-38999 (LJT/HE308, TV..)

Subminiature cylindrical connectors were developed to meet the needs of the aerospace industries and provided the impetus for development of the MIL-C-38999 specifications, which recently were superseded by MIL-DTL-38999. Circular connectors MIL-C-38999 are available in different materials such as aluminium, stainless steel, marine bronze, composite and with various surfaces such as zinc-tin, green cadmium, black-zinc-nickel and nickel-plated.
