ENGINEER PA-09 Precision Micro Connector Crimping Pliers 175mm. Made in Japan. Crimp AWG #32 to #20 Wires across 100 Different Terminals & D-Sub Connectors Contacts

If you are a Hobbyist, buy these. Skip the cheaper ones you can find. These were so good, that I ended up buying a size up, and an extra pair so I always have one in reach. These are a must have whenever I work on my 3d printers, Electronics etc. Pros - High quality and durable - Versatile and compatible with various connector types (JST, Molex, etc) - Precise and consistent crimping results - Comfortable handle / Feel Good to Use - Easy to use - High level of control Cons: - Expensive compared to others - You might need some practice before you master them (due to them being completely manual) - Doesn't work with barrel connectors (IE Spade, etc) that you commonly find at local hardware stores Additional Details: 2 versions of these pliers exist, Taiwan and Japanese made. I've had both in my hands but of different sizes. The Japanese ones are subjectively better, but I wouldn't return the Taiwanese ones. The only major difference is that the Japanese ones have the crimped connectors slide out easier. There are some minor visual differences as well. I mostly view these as a hobbyist tool, if I were using these everyday 9 to 5, I think I might get something else. They are very much a "do it once, do it right, take some more time to do it" type of tool instead of churning out millions of connectors. Though I'm unaware of anything better, these are just so dang good.

I used to think crimping was a waste of time and money, especially since companies like Molex charge $Texas for "proper" crimpers. As a result I would normally solder terminals onto the ends of my wires, and sort of bend what was left with some needle-nose pliers to make it fit into the connector body. Then I did a couple projects where I spec'd PicoBlade connectors. These things are pretty diabolical and soldering them basically rendered them useless because they are so small, and the solder basically wicked everywhere you don't want it. Finally desperate enough, I decided to try the PA-09. It's well-built. Solid, no play in the joint, and does not shift or deform at all while you are doing the crimp. The grip is also solid. I would probably not want to do 100+ crimps in one sitting with this thing, but I can't imagine wanting to do that with any crimper. The docs are brief but effective. You want the sides of the connector to be parallel when you place it into the tool. If it's not, you picked the wrong size, and you will get bad results. I think I managed to destroy one PicoBlade terminal and after that I was producing perfectly serviceable crimps. I've gone on to crimp other terminals as well and it's unlikely I will go back to soldering them. One thing I would mention, and feel silly for not realizing at first. Normally you have to make two crimps to put a terminal on the end of a wire. One for the actual conductor, and another which crimps into the insulation as kind of a strain relief. I made the mistake of trying to use a larger size for the insulation crimp. They are the same size. It makes sense when you think about it, but of course I did not think about it.

This made in Japan version is an authentic Engineer precision PA-09. Please Don’t be full by the Made in Taiwan version. My first order on Amazon was fulfilled by one of the sellers from Japan, but it was made in Taiwan, so I immediately know this was fake and return it. Thus, I reached out to another seller based in the United States and it was confirmed he had Made In Japan version which is true authentic. ( why? When you buy it from other parts stores, it’s all made in Japan) The tool is excellent to crimp all kind of connectors, after I received it today, I had already crimped 20 JST-XH connectors without any issue.

Let me start by saying that these Engineer PA-20 Universal Wire Crimps are the best you can find on Amazon for under $50. They beat the generic blue handled crimp tools and many of the ratcheting crimp tools. It took me some time to decide on the PA-20's but I wish I would have purchased them first over the other two tools that I tried out. The Engineer PA-20 is well built and seems like it will last a long time if used properly for its intended purpose. I like that the crimp tool has a plier-like nose so you can manually shape terminals to hold wires in before accomplishing the crimp. The 4 size options will cover most of my needs working with smaller automotive connectors. The die is shaped and sized accurately so that the terminals don't bend or get crushed when performing the crimp. I tend to use the size up for my initial crimp and then the exact size to finish off the crimp and I always achieve great results with that method. Overall, the Engineer PA-20 is a great precise tool that I will get lots of good use out of. I will be looking to their other selection of tools for future projects. Previously, I had purchased and used this linked ratcheting crimp tool. It made a complete mess of the terminals I was working with even though it was rated for 22 gauge wire and terminals. Also, the ratchet didn't release until you completed a full crimp which often times resulted in too much force being applied. All in all I found I prefer the manual crimp tool over the ratcheting crimp tools since you can control force and accuracy.

Used these to crimp SXH-001T-P0.6 connectors (22–28 AWG) for a 6S FPV battery. Worked well.

Crimpadora en dos pasos. De calidad excelente, se ajusta a la mano perfectamente.

This is exactly the tool I have been after. I haven't been able to find a tool to crimp a specific type of terminal I use regularly but this has worked a treat. Basic easy to use tool allowing for perfect crimps.

Fait un travail précis et de qualité pour le sertissage de cosses miniatures pour connecteurs JST et semblables. L'opération doit se faire en deux temps pour la partie conducteur et la partie gaine du fil, et la pince a l'épaisseur appropriée pour cela. J'utilisais jusqu'ici un modèle plus gros (pour cosses de connecteur type MOLEX KK), dont les mors ont deux sections différentes permettant le sertissage des deux parties en une seule opération, mais leur épaisseur est trop importante pour les cosses miniatures. Vue la simplicité du mécanisme de la pince, il ne devrait pas y avoir de problème de durabilité.

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