Micro Molex solution - slice them off, use gold D Sub pins and sockets and a bit of heat shrink.... Move on

I think that is because the tooling assumes a thicker commercial PVC type insulation.

Our Tefzel stuff is pretty thin compared to most insulation.

Or just use the Dsub housings. In any case, Dsubs are much better quality and fewer headaches down the road. The Dsub pins are rated up to 7 amps each (5A if you want to be ultra conservative), and you can use 6" pigtails to parallel multiple pins if you need higher current.

If you insist on using Molex style terminals, know that the industrial quality crimpers (at least the ones I have access to, that spent their previous life in a GM/Packard/Delphi wire harness plant) do a 'B' crimp on both the wire and the strain relief (insulation). The insulation crimp is just a slightly bigger version of the wire crimp.
