What tool should I use for crimping of a cable AWG22\19 (Stranded)
Use a special chart that will let you compare AWG with mm². AWG 22 matches the cross-section of a wire 0.32 mm². It is a stranded cable, so you will need pin terminals 0.32 mm² and a crimper ПКВк-6 made by KBT. But if you deal with a pair of 5e, maybe it will be better to use a special scotch lock splice connector.
