ENGINEER PA-21 Engineer Precision Crimping Pliers, Crimping Tool, Open Barrel, Long Barrel Terminal

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 controlCons:- 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 storesAdditional 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.

If you've ever had the misfortune to crimp any number of small (<2mm) pitch connectors with a pair of needle nose pliers, you know how painful that can be. While I have never used the "official" crimpers from JST or MOLEX (>$400), these crimpers are a dream to use compared to trying to do JST-PH or ZH connectors with needle nose. They are not some cheap stamped steel affair, but precision ground tools, that feel great in your hand and do the electrical and insulation crimps perfectly every time. While there are other, cheaper crimpers out there, these are the only reasonably priced ones i've found that go down to 1mm, which is essential if you want to crimp the smallest JST connectors (most bottom out around 1.6mm).My only compliant is that the connectors sometimes get a little stuck in the tool and require a little wiggling to remove them from the jaws, not a big deal, but a little annoying, especially when you're working with thin wires that have a tendency to break.So far, I have used these with JST-XH, PH, and ZH connectors and they work perfectly. If you're working with these connectors with any regularity, I highly recommend that you buy these crimpers and save yourself a lot of frustration,

I use this crimp tool to crimp the tiny little JST series connector pins. It is the only tool that I have found that does the job very well. The tool is made in Japan and is of very high quality... it should last a lifetime of crimping these tiny terminals.

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 crimping tools is perfect. Simple, light and really sturdy. Will sure last for a very long time.

Cometí el error de comprar pinzas genéricas para ponchar cables en un inicio. Vaya error, pues solo salía bien una de cada 5. Tras estar lidiando con dichos problemas me decidí a comprar este modelo por recomendación y la diferencia es muy notoria. He ponchado molex y jst con estas pinzas y quedan perfectos a la primera, ya no tengo que comprar conectores de repuesto a cada rato. Totalmente recomendadas.

Looks cheap, but is a very precise tool. Works perfectly.

Pince de qualité, très précise, on ne loupe plus ses connexions à conditions d'avoir des conducteurs de qualité.
