Selecting the Right Tool

We also have a less expensive, narrower (4 mm) crimper that can also crimp JST connector, JR, Futaba J, and 0.1" housing crimp pins, though this alternate tool can only crimp the full extent of wire barrel on the JST pins. You can use the following table to help you decide which cavity of which crimping tool you need:

Using the Crimping Tool

Prepare the wire by stripping about 1/8" (3 mm) of insulation from the end. Place the wire in the crimp pin, lining it up so that the stripped portion lies between the inner set of tabs on the crimp pin, while insulated wire lies between the outer set of tabs.

Place the wire and crimp pin on the appropriate tooth of the tool’s die, making sure that the insulated end is on the raised and wider half of the tooth. The tabs should point toward the cavity on the other side of the die so that the tool bends them inward around the wire when it closes.

Close the jaws of the tool slowly and completely until they release. The tabs on a properly crimped pin should form one barrel around the wire conductors and another barrel for strain relief around the wire insulation.

Tip: The strain relief barrel sometimes ends up a little overly flattened, making it too wide to fit comfortably into the crimp pin housing. In such situations, you can use a pair of pliers to gently squeeze the wider axis of the barrel into a more cylindrical shape that will slide easily into the housing.

One of Pololu's customers has made a very nice video tutorial that talks about how to make custom cables with Pololu's pre-crimped wires and with self-crimped wires. The section on using Pololu's crimping tool starts at approximately 4:15 and shows the process in detail. One of Pololu's distributors has also made a short video tutorial that shows how to use this crimping tool.

This useful inspection chart (pdf) by JST shows properties of good and bad crimp connections to look out for when checking your own connections.

    These take quite a bit of practice to use - especially with fine connectors. Handy once you get the hang of them. Youtube is a useful resource for how to's! (Posted on 20/10/2017)

    Well built. Crimping the ends is pretty fiddly, but with practice it's not too bad. The video explainer is helpful. (Posted on 14/09/2017)

    Works really well. Feels solid and the mechanism responds well. A little pricey, but have nothing to compare to, so it's worth the money at the moment. (Posted on 26/09/2016)

    Of the low-end crimp tools I have tried, this one was the most successful, however it should be noted the "Pololu" tool is just an unbranded SN-28B model which can be easily bought for approx. one third of the price from lots of other places. Sometimes they will still not easily go into the connector shells, and overall I would say the success rate of the crimps is about 60%, which is pretty atrocious really. (Posted on 17/05/2016)

    What a great tool to crimp those mongrel small male/female crimp pins... It did take me 3 or 4 crimps and then a short session on youtube to get it right (Posted on 14/03/2016)
