Re: Amazon Molex Kit
Yes I also bought one a couple of months back and agree it is good value, I did have to buy a suitable crimp tool to fit them.

Re: Amazon Molex Kit
The key to crimping these tiny connectors is to make sure thet the two arms of the crimp area fold right down in the middle and crush the wire properly. A bit like a rounded "B" in cross section. Just squeezing with pliers leaves a very weak joint.
I laboured for ages trying to get a good crimp on these tiny connectors with pliers and finally gave up and bought the Engineer PA-09 crimper. A seeming over-expensive and simple tool. But it has been perfectly designed and made to do excellent crimps, and works over quite a range of the smaller crimp connectors. A good investment if you are making lots of these crimps. And I suggest you don't make the mistake I used to make of then soldering the crimped joint "just to make sure". This guarantees that the solder wicks up the wire, making a nice fracture point a little way up from the crimp! -Jeremy

Re: Amazon Molex Kit
40 Quid for a crimp tool, the last Molex one I bought (for work) was £300. I tend to harmonise (silly word for use the same) work and home connectors, I can borrow the tool (and get free connectors too), win win!

Re: Amazon Molex Kit
Yes I agree somewhat but I personally have no problem paying the money for good tooling, likewise with crimping terminations for Hi end and esoteric hifi with eye watering costs of cables etc, the terminations have to be spot on every time. But shall still be looking to making a purchase of something that fits the bill and its only small scale hobby things and projects these days. Years ago when we used lots of crimping activities with Car Radio etc installation and auto electrical works some of those were a bit trial and error, but smaller and much more intricate things at this level do require more precision style tooling so long as it does the job properly.
