ENGINEER PA-09 Super-Precise Crimping Tool (Made in Japan) Works with AWG32-20 Open-Barrel JST ZH, PH, XH, SH/SHL, Molex KK, Picoblade and Other Narrow-Pitch Connector Contacts

Best tool I ever had for JST crimping, including ZH size, which is tiny. Recommended.

This tool exceeds its simple looking appearance

Just received my PA-09 and was happy till I saw the Made In Taiwan stamp on the packaging prompting further inspection of the product. I found the following on my fake ones. 1- Made in Taiwan not Made in Japan 2- No engraving on the tool handles (Made in Japan like in pics) 3- Latch mechanism is different and uses a rivet instead of screw 4- Coating seems glossier than the real ones 5- You can see the tooling of manufacturing process on the backside. 6- Then engraving i.e. size of die is smaller and fainter than the original Japan ones. While the quality of the Made In Taiwan seems to be good, its just not what was advertised. I should have read more carefully about the seller before I made the purchase. Finally, I felt so deceived I immediately initiated the return within 30 minutes of receiving the fake products and Immediately purchased from Amazon UK as they seem to sell them. Am putting 2 stars for the fake one.

Love this thing, anyone who doesnt has a skill issue.

I’ve become a big fan of ENGINEER tools over the past year, and they’ve quickly become my go-to brand for precision electronics work. The quality and attention to detail have been consistently excellent, and these PA-09 crimpers are no exception. I already own a ratcheting crimper, and while it’s great for larger terminals, I’ve found it to be a little too bulky and aggressive for delicate JST and other micro connector pins. The PA-09 gives you much better control over the crimping process, allowing you to feel exactly what’s happening instead of relying on a ratchet mechanism. That extra precision makes a noticeable difference when working with tiny open-barrel terminals. The dies are well-machined, alignment is excellent, and the finished crimps come out clean and secure with very little effort once you get the hang of the two-step crimping process. It’s a versatile tool that handles a wide range of small connector types, so I don’t need a dedicated crimper for every style of terminal. The build quality is exactly what I’d expect from a tool made in Japan—solid, smooth, and built to last. If you spend much time assembling cables for electronics, 3D printers, RC projects, or microcontroller boards using JST, Molex, Dupont, or similar connectors, this is a worthwhile investment. It isn’t the cheapest crimper available, but the improved control and consistently better crimps make it well worth the price.

Wow do these work well. I struggled for some time with another brand of ratching crimpers that were cheaper and thought would suit my intermittent use needs. I had all but given up on making JST crimps since most of the time they mangled the connector or the crimping was not tight. For my first few crimps with these, I tried the 1.9 mm die for some smaller JST connectors. Once I switched to a smaller die every crimp was perfect. Goes to show what a quality tool can do.

Excellent product. Tried a cheaper random brand ratcheting crimper and all it did was make a mess. These units have a precision jaw profile and the JST crimps actually work. Narrower profile allows a better view of what you are crimping and taking two crimps to complete the termination is not an issue.
