We’ve used the Hansen Hobbies Deluxe ratcheting crimper on the Hansen Hobbies pins. My strategy is to use precision needle nose pliers to first slightly form the strain relief “wings” over the wire insulation to hold the pin onto the wire. Then the assemblage us placed into the large side of the crimper die and crimped, then into the small side of the die and crimped again. It’s about a 90% success rate this way. They come out acceptable. Not as good as factory crimps done with a more precision tool, but plenty acceptable. It does bend the pin slightly which I manually straighten with my fingers.
We also have the red handled crimpers from Hansen. I find them difficult to use and not great.
We also have the JST SM series pins and official JST crimpers. It’s a different crimper for male and female and around $500 ea, it’s no small investment. But, they work absolutely flawless. There’s a reason good crimpers cost a lot. I will say though too, due to the cost, these get kept put away, and are only used with supervision/authorization.
Finally, we got the Molex 638111000 on FIRST Choice. Haven’t had a chance to try it on anything yet. I think it may not go small enough for CAN or PWM wire.
