I use a ratchet type crimper that is side entry and is a "one size fits all" solution from 0.25mm to 6mm cable. It is dieless.
The wonderful thing about this beast is that it consists of 4 sides that form a rectanguler die moulded type crimp. With this little beasty I can quite comfortably fit a 1.5 sq mm ferule crimp in smaller relay bases such as Omron P2RF type bases, the AB equivalent, the Izumi equivqlent, Finder, Telemecanique (Finder) etc.
The standard type ratchet crimper tends to spread the ferrule and this makes it very hard to fit into many pieces of equipment out there. The square die type crimp makes it easy.
These things are probably available world wide but are certainly sold in Ozz by a company named Cabac.
Unfortunately the link to the little dear in their catalogue is broken. If it comes up again, I will post the link here.
By the way, our local Legrand product manager took away some sample crimps to send back to France. He was very impressed.
I have given away Weidmueller crimpers and cable strippers as I consider them to be plastic toys. They do not last. I have thrown away 100s of dollars worth of the damn things. Have gone back to the old "Tyranasaurus Rex" type strippers thank you. They are front entry.
