Description: These crimping pliers allow you to easily make your own wiring harnesses using crimp pins and cable housings. These are not a regular set of crimp pliers. These pliers are capable of crimping very small 1.00 - 1.9mm crimp pins. These work well with JST PH, SH, SHL, and ZH series pins as well as DF14 HRS and micro-latch from Molex. A similar set of crimpers from JST can be more than $400! We found these pliers to be very high quality at a great price.

  • It would be cool if you could offer a little started kit of connectors so we could play with all the different types these support.

  • Forgive my lack of knowledge when it comes to connector types. Will these crimp pins for standard 0.1" housings?
    For example, something like this?
    Thanks.

  • I have a crimper from below link, best crimper for the jst ph contacts i have found

  • Will these work with the connectors found in the WowWee Robosapien V2 robot. If they do which connector should I get as well?

  • These are a fantastic crimper and a great price. We use them for JST crimps. They get a hammering at our workplace and are still going strong, just ordered 5 more.

  • Do these crimpers work with the 1.25mm Molex Picoblade pins? It seems that there are not many good/cheap options for working with the Picoblades, so it would be wonderful if these worked.

    EDIT: I found a pin-compatibility chart from the manufacturer which includes the Molex Picoblade, but no mention elsewhere in forums about how easy/effective they are.

  • Yes the price is right (I guess precision dies cost a bit to make!), if you’re UK based & in a hurry, they can be bought this side of the pond too, for example…

  • These are good quality crimpers, but when using them with the JST-RCY connectors, you do need to pre-squeeze the insulation retainer portion of the pin first. Otherwise, it is too wide to directly crimp in the largest die position. Other than that, very nice.

  • Is the price correct? £37.23 seems a bit steep when I can get some for around £8 somewhere else. Evidently they’re not the same standard, bu they do the job.

  • Just received these today, a few days after receiving two other crimpers from Pololu.

    The Pololu crimpers http://www.pololu.com/catalog/product/1929 $29.95 and http://www.pololu.com/catalog/product/1928 $34.95 have a better build quality and a more advanced ratcheting mechanism, as well as being designed to crimp both the conductor and strain relief in one pass.

    • Could you measure the barrel width of the pololu crimpers like the PA-09 shows in step 1-1, and put them on your site (or here?) That would be awesome.

      The PA-09 indeed works with JST-SH pins. But wow are those things tiny. Don’t squeeze too hard or it flattens the barrel out and doesn’t fit in the header. Took me 8 pins and two headers to get a single 4 pin header built :p

      • conductor crimp widths : 1.41mm and 1.56mm for the TWO position crimper. AND 1.69mm, 1.93mm and 2.18mm for the THREE position crimper. I did not measure the strain relief crimp widths.

        For comparison, using the same method for the PA-09, I get 0.99mm, 1.41mm, 1.53mm, and 1.86mm for dies nominally “1.0mm”, “1.4mm”, “1.6mm” and “1.9mm” respectively

        I used my best caliper measuring technique, but the “inside” prongs on hand calipers are notoriously lacking in accuracy, and I don’t have a set of precision gauges.

        YMMV!

  • Got them in the mail a couple of weeks ago. First impression: very sturdy action and soft, comfortable and grippy handle. Good quality rubber. Did a first crimping job today on crimp pins. Result - perfect! Very quick and precise.

    5 out of 5. “Made in Japan” still means something today.

    BTW: Looked for a similar tool in the Knipex lineup. Found only a combination of a tool and a special attachment for different pins. Very versatile, but the price for the 2 added up to nearly $600.

  • These work amazingly well. They are not for production use but for prototypes they work awesome. You must crimp twice and be careful or you’ll cut off the wire (the process is not easy, don’t fool yourself). But eventually you can produce great cables for prototypes.
    I used the crimper on SPH-001T-P0.5L and SPHD-001T-P0.5L, part of the PAD connector series. Worked great. It is literally impossible without this tool (I tried, gave up and tried solder, and it was FAIL).

  • Do these work with JST XH series conncetors?

    • Not bad crimpers for $60. They won’t beat a nice pair of Molex Crimpers ($300+) but they work for my side projects.
      I got them to work well with the Polarized Connectors (see products below). Now onto to connectors of choice - JST XH series.

      • So did they work with the XH series of connectors?

        • To answer my own question, I’ve received these and they do a fine job on the XH connectors.

          $60 is STILL far more than it could possibly cost to make these, but that is the world of crimpers, these work, and they’re among the cheapest. So take it with a smile I suppose!

  • Used this tool with various connectors e.g.
    example
    And here is a compatibility chart from the manufacturer
    Works great after a little practice.
    You have to crimp twice. Much faster than soldering and more control (crimp both times with the correct diameter).
    Because the metal “flap” is curved inwards the connection becomes tight and strong.
    There is also a little larger version (PA-21) here with here a youtube instruction
    Regards, Leo

  • I don’t understand what makes JST crimpers so expensive? I mean:
    Plastic $1
    Metal $5
    Tooling $10

    • You think $60 is high? try $925!!!

  • I could have really used these a couple months ago when I made a VGA cable for my home server.

  • I’ve just been using needle nose pliers and then soldering the pin and wire together but these would be nice to have.

    • I’ve used both and these are MUCH better. If you’re going to use them a lot, it’s worth the money.

  • Any chance for a crimping tutorial? I’ve seen a few guides online but I still can’t figure out why I only get 1 out of every 6 right, even with tons of practice. My finished connector blocks with crimped wires also come out terribly and I hate having to hot glue inside the access holes just to keep them from popping out of the housing when I plug/unplug.

    • There’s a little mini picture tutorial on the back of the box. It’s pretty easy if you have the right tools.

  • Added to the wish list !<br />
    <br />
    You know if it works for RC servo style crimps ?<br />
    <br />
    Regards,<br />
    Thomas.

    • I have a similar pair of crimpers, perhaps slightly different, that is actually too narrow for standard servo connectors like futaba or hi-tec varieties. It still works, but you have to crimp twice for both insulation and conductor.
      What you want is something like
      http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=WM9999-ND
      for servo connectors.

      • I use this for LiPo balance connectors and servo connectors all the time. I am the go-to guy at the RC track it seems like :D. At work I also use the Molex crimper that you linked to. I would have to say the fit and quality of the PA-09 (this one at SparkFun) is better. With the Molex we had to grind the top side down because it was too thick and you couldn’t get a separate crimp on the insulation tabs and the contact tabs.
