The ones I used are .093 which are good for wire awg 22 to 18. I also have the same crimpers, they work good enough on this type of connector, you need to be careful. |

Nowhere near Nep's production values--or budget. >:D Unformed and preformed Molex .084" female pins. Once the preform is done insert the stripped wire and pinch the insulation tabs in just enough to provide enough friction so the wire doesn't shift too easily. Position the pin and wire in the jaws for crimping with the wire on the numbered side and the open ends facing into the recessed side of the crimp. You end up with a not-very-pretty crimp that has a good mechanical and electrical connection. Unlike D-sub connectors, the molex housing has lots of room for ugly/flat crimps. The one for the green wire turned out a little better, but I don't have a pin extractor. Scott |

Ah, OK. You're basically just mashing them. I didn't think there was any realistic way to get a contact that big into the little Radio Shack tool (which, while remarkably versatile, is not really meant for stuff this big) and do a normal wrap-around crimp. You can probably get a lot more force than the normal needlenose trick, and hey, if it holds, it'll work. The crimp tool will probably not last nearly as long as it might when using it on "appropriate" size contacts, but they're a whopping nine bucks, so who cares. FWIW, the PA-21 I have crimps this series pretty well (down to the #18 size contacts - it can't do the ones intended for giant wires correctly), but it's like a $60.00 tool. Despite having a couple of generally nicer tools, I actually keep one of the Radio Shack ones around. It actually works better on certain kinds of contacts (the ones where the jacket retension is meant to form a circular opening and has the two prongs offset e.g. Harwin M20) than my PA-21 and PA-09 does. Price is certainly right, and they're easy to get. If you want a nicer tool for this series, Molex has a largeish "Universal" tool. It's commonly found in KK and 0.093/0.062 field service kits and is reasonably priced standalone (~$30, I think). It does OK on things about this size. It looks like the Molex contacts for this series don't have the excessively long insulation prongs that the AMP ones do, which is what makes the real crimping tool somewhat essential. |

A somewhat controlled and slightly shaped mashing, but yeah, I've been just mashing them. I have been looking for some better crimpers before I (eventually) wire up the D-subs on my portable/modular. I've used some nice ratchet crimpers before and they are definitely the way to go if you don't mind shelling out the big bucks. For those of us who are a little more budget conscious, Nep posted some suggestions and links for inexpensive crimp tools here. Scott |

Molex .062 FTW! :D |
