Review: A simple set of crimpers, that work extremely well. - Another excellent quality tool from the Japanese 'Engineer' company. These are a pair of manual crimpers for individual connection pins, such as Jst or Dupont pins. They are spring opening, with a catch to keep them closed when not in use. They come on a blister card, which has some helpful instructions and sizes on the back. (Photo). There is nothing fancy about them. There is no ratchet mechanism, no holding mechanism. All you get are a pair of manual grip crimpers. (Photo). Fortunately, none of that is really necessary and these work extremely well. In fact they are the best I've used. You place the pin in the relevant sized hole and squeeze. You do the conductor first, then move the pin to crimp the insulation. It works extremely well. Just make sure you use the right size hole. It can be fiddly, so it's a massive advantage if your pins are still attached to their manufacturing strip. You can still crimp the pins if they are individually loose, but it is a lot more fiddly. 'Engineer' do 3 different sizes of these crimpers. I personally think that these, the PA-20, are the most useful. I have never had to use a size bigger than 2.3mm or smaller than 1.6mm in all my years, so, I can't imagine needing a different pair. Your circumstances may be different, but if you are crimping standard 2.54mm pitch pins, these are the ones you want. Overall, these are a great set of crimpers, that work really well. Yes, they are a little expensive, but with nothing to go wrong, there is no reason why these shouldn't last a life time. Recommended. I hope you found this review helpful.
Review: Well made, but not without problems. - I have been using this now for a couple of cheers to crimp JST pins onto ribbon cables, I love the JST connectors but I really do not like crimping them. There's a definite "knack" to using this tool, and even having crimped thousands of these, I still find them very fiddly to crimp. The JST crimps have 2 tab sections, one is used to crimp to the insulator ensuring that the cable is held in place, and the second is the actual terminal itself. The method that works for me is: 1.) bend the insulator tabs inwards very slightly with needle nosed pliers, if you don't do this, you won't be cable to perform the actual crimp. 2) place the crimp into this tool, I rotate the tool in my hand so the legend is facing away, I need to do this is ensure that I'm only crimping the insulator and not the other tabs, I gently close the tool slightly to grab the crimp, then rotate the tool back so the legend is visible, the back of the connector is now facing me. 3.) As I'm looking at the rear of the crimp, I insert t he cable into the crimp and look at the other side to make sure that I haven't pushed the cable in too far or not enough, it should be positioned so that the cable insulator is touching the outer tab, and the conductor is touching the inner tabs. 4.) very carefully I close the tool to perform the crimp. At this point, you might get a good crimp, or, you might end up with the crimp rotating in the tool jaws, in which case you have to reset everything and try again, the final problem you may get is that the tabs just didn't fold properly, in which case you need to remove the crimp/cut it off/trim the cable and so on. If the crimp was OK, then you repeat the process again, and crimp the inner tabs, just make sure that you check that you are not crushing the end of the crimp, if you do the pin won't be usable. Other issues also include the crimp bending. It works reasonably well most of the time, but sometimes they can be infuriating, especially when the tabs don't fold properly. This is a common issue I've read with this tool, but this is one of the best tools for these crimps, so I kind of just live with these issues. Take your time, and inspect everything before you make the actual crimp. It's also well worth having a multimeter set to "beep" mode, after crimping you should check that the cable is ok, sometimes the cable may more and the conductor might make no or poor contact.

## Questions & Answers

**Q: Can anyone tell me how thick the jaws are on these?**
A: The manufacturer (Engineer Inc.), have a specifications table on their product page ....http://www.engineer.jp/en/products/pa09e.html  ....the column you need is the one headed   Dies T(mm)    (the T is short for thick)

**Q: Will these work with molex 505153 crimps?**
A: Yes, the molex 505153 is for AWG 22-24 and this tool covers AWG 20-32. as with all small crimps it is fiddly to use and you will ruin a few connectors before you get the knack.  It is not a single stage crimper. I find it best to crimp the conductor first then the insulation.

**Q: Will this crimp tool crimp connectors for the jst ach type connectors?**
A: Having researched jst ach type connectors it is evident that the PA-09 crimp tool is suitable.

**Q: Will they work with jst sm connectors?**
A: With practise I think yes. I have found them excellent for the price. Very small connectors are difficult unless you pay out for crimper many hundreds of pounds. Had cheaper crimper but they all went in the bin. Buy the best you can afford!
