Recommended Crimping Tool for JST XH
I needed to crimp approximately 300 JST XH connectors as part of a home automation project. I initially used a non-original universal crimping tool, which completed the task but did not produce results that met my expectations. I also considered purchasing the original JST crimping tool; however, given its high price and my occasional need for such work, it didn’t seem cost-effective. I was pleasantly surprised by the results — both visually and functionally. The connector wings are neatly rounded and securely attached to the wire and insulation. So far, I’ve crimped 16 JST XH connectors with zero failures. Overall, I highly recommend this crimping tool for anyone working with JST XH connectors.

Conforme
Plus petite que je n'imaginais, mais conforme. A l'air solide et précise. A tester en condition réelle.

Känns gedigen och bra
Köpte den till JST SH men behövde till PicoBlade, visade sig att tången skall passa båda +++

It works! And very well!
Bought a blue crimper sometime ago and was never successful in crimping connectors without wasting connectors. Especially micro JST connectors, was persistent in trying100connectors and all failed. I almost concluded it is the fault on my part until I bought Iwiss crimper. I was successful with the first try.
