MIL-DTL-38999 Connector: Selection and Application Guide — How to Choose the Correct Contact
The selection of contacts depends on your current and signal transmission requirements:
Signals and low current: #22D contacts are the most common choice, accommodating 24-28 AWG wires with a rated current of approximately 5A, suitable for high-density signal transmission.
Power and high current: #20, #16, #12, or even #8 size contacts can be selected, with rated currents ranging from 7.5A to 40A.
Termination methods: There are three main types: crimp, solder, and PCB. Crimp-style contacts are the most widely used due to their high reliability and field repairability.
