| Where can I buy molex connectors with pins? |

The "25 cycles" of plugging/unplugging duty refers to the flat white Molex "KK" series used on the Williams pinball sysyem 3 to 7 pinball machine circuit board interconnector. Regular .093" Molex connectors far outlast that by quite a bit. Normally the .093" connectors are rated to handle 8 amps per pin but many people 'share the load' by splitting power to two or three pins just for redundency's sake. I buy my Molex connectors from Mouser Electronics. The correct Molex hand crimper tool for the .093" terminals (and KK series .156") is the red handled # W-HT1919 (GC/Waldom Electronics). It will always crimp to the proper tightness with the terminals it was designed for. If you crimp .093" terminals with the yellow handled tool you will crimp too tight or even cut through the wire or chop off the terminal. The yellow handled tool is made for smaller terminals. AMP brand terminal & connectors use tools all their own since AMP terminals are different sizes/shapes/diameters (and are patented!). Sometimes you can get away with using a Molex crimper to crimp an AMP brand terminal. I don't recommend it though. Personally I use all Molex connectors since AMP is so far overpriced on their connectors, terminals, and tools. The only time AMP connectors make sense is if you're a manufacturer. Then AMP gives great price breaks. For little guys or the average repairman, AMP simply costs too much. Every control panel I build or coin counter/service/test switch panel I make gets MOLEX .093" connectors. I've been using these tools for 25 years and the red handled one is what I use most followed with occasionally needing the yellow handled one for .062" and KK .100 terminals. |

If you are only going to have one set of crimpers for Molex connectors, get the yellow handled ones. There is no such thing as too tight of a crimp, as long as it doesn't flare out so that it won't fit in the housing (which I've never had a problem with). I've crimped plenty of .093 Molex pins with the yellow handled crimpers and they come out fine. A crimped pin only has to do 3 things: - Stay secured to the wire - Fit in the housing - Conduct electricty If those three conditions are met, the crimp is fine. I've never had an issue with cutting through the wire or chopping off the pin. |

Ok, thanks for all the help ! |

fwiw, http://sayal.com/ has tons of molex connectors of various shapes and sizes and pinouts. I got a 3x2 config for my Betson trackballs there. And they are just up the road from me :) |

Crimper + Dies = £160 And that was 2 years ago........ |
