ENGINEER PA-20 Universal Connector Crimping Pliers, 175mm, AWG 28-18 | Made in Japan, Crimps 100+ Terminals, Molex, TE, JST, HRS, D-Sub, 4 Die Widths (1.6-2.3mm), Oil-Resistant TPR Handles

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.IWISS SN-48B Non-Insulated Tabs and Receptacles Crimping Plier AWG26-16 0.14-1.5mm²

I don't know why I waited so long to buy one of these. They are so much better than ANYTHING I have used from the China suppliers. This feels solid, works well and does a very good job at crimping. I cant thank the EE that recommended these instead of the ratcheting crimpers for JST and Dupont connections enough. Sure you have to do two steps to crimp the insulation but its so much easier to crimp I dont mind the extra step. Just buy them and quit reading this review.I plan to add more of this brand of tools to my shop. They outperform everything else ive tried.

Driven by the need to create 25 - 30 custom sized servo connections for a multi-rotor project back in late February, I bought (for $13.47), the ratchet style of crimping tool and went through more than 100 female dupont crimp pins and a meter of 3 strand 22ga servo wire, and couldn't successfully make 1 custom servo extension.Late in March I bought ($8.33), a very simple plier style with 3 different sized crimp stations, they are better, but still no joy.Today, late in June I received a pair of these Engineer PA-20 crimp pliers (for $36.80), and can honestly say they are a joy to work with. As soon as I had a chance to make some test connections, I made 6 crimps and the were all near PERFECT !Rather small in size, they fit my hands well. The lack of compound leverage isn't a problem and might only be an issue if used in a high volume production role.What can I say? If you want the best result at an affordable price, don't hesitate, this is the correct tool.I had been searching for JST crimp pliers and did learn the JST stands for "Japan Solderless Connector".It makes sense, if you solder the wire, with a little luck or practice, you can get a strong connection. The problem though is that the solder wicks past the strain relief tabs that encircle the wire and the insulation, making that point brittle inside the insulation. Vibration and flexing causes the wire to fracture there.I just wished I'd bought these Japan Engineering PA-20 Connection Pliers first, I don't need the other 2 crimp pliers now.

Good quality crimper makes solid and secure crimps. I wanted a ratcheting crimper but couldn't find one in the right size. I purchased a different two cavity non-ratcheting crimper that was advertised to work with the crimp terminals I was using but one crimp cavity was too small and the other was too large. This crimper is just right! It apparently has every crimp size in the range it covers so it's more likely to fit the crimp terminals you have. The build quality is also very good and it's reasonably comfortable and ergonomic. I wouldn't want to make a thousand crimps in a day with this crimper. It's not a production tool, but for engineers and technicians making a couple of dozen crimps for some project as I did, it's ideal. Make sure the crimper handles completely close. You can see this as well as feel the handles close together. Then give the wire a gentle tug to verify that the crimp is tight. I had zero failures out of 24. I did double crimps - one for the wire electrical connection and the second crimp to grab the insulation to mechanically strain relieve the crimped connection.

I can't give a comprehensive review of this product yet, having only recently received it. Having said that, I did use it to crimp a few JST terminals and it performed well. It is not quite as easy to use as the OEM crimper, but at close to $500 per crimper tool for OEM models, this tool is far more economical, at least for intermittent use. This is especially the case when you need several different types of terminals, each requiring a different OEM tool.The tool comes with an instruction set, including photos. There is also a video on Youtube showing how to use the tool (this is how I found it in the first place).

These are GREAT for making molex .156 and for making smaller dupont connectors. The crimps are there for both of those sizes (and others as well). I succeeded in making Dupont connectors w/20 gauge ETFE wire, so long as I didn't try to stick too much of it down into the connector.Basically this tool is accurate, nicely coated, nicely made. Most of the other tools in my box look a little inferior next to him. I think I will end up buying an engineer wire-stripper next to match this as I do a lot of stripping and soldering.I wouldn't change a thing about this tool. The range is good, the "feel" is good, the grips are nice.When they say "Recommend faster shipping option" -- believe them, LOL. Mail from Japan is slow as Christmas.

I am not aware of a crimper that will do the tiny connectors used on my KTM and Ducati other than this brand. It is the one sold by the connector company's I use online. I guess the reason is it works PERFECTLY. It is super precision and crimps great. I do wish it was cheaper, but that's just me being cheap. I am happy with the results.

Like many here I first tried two cheap racheting crimpers with dismal results. If I got one successful crimp out of ten I was doing well. I use crimpers for "Dupont" pins as found on servos, Arduinos, etc. Here's the problem--researching crimping tools I found no specification for how thick the jaws are. The cheapies have jaws about 8 mm thick with two cavities, one for the wire crimp and the other for the strain relief crimp. The problem is that inserting a pin just right, so the two cavities line up and the ears are vertical is almost impossible. A slight misalignment, either in-out or rotated, ruins the crimp. And the ratcheting action makes it even harder to capture the pin without starting to bend the ears before inserting a wire.As many instructional videos correctly state, the way to crimp these connector pins is to do it in two steps, first the wire crimp then the insulation strain relief crimp. I tried doing this with the thick-jaw crimpers, but found it impossible to crimp one without mashing the other. These crimpers provide the solution, jaws that are only about 3 mm thick. Plus, the NON-ratcheting action gives you a delicate touch in gripping the pin before inserting a wire. I had to stop my initial crimps (10 for 10!) to write this review. I found the 1.9 mm well is perfect for the wire and insulation of 24 gauge stranded wire. After the first crimp I pinch the insulation ears so they stand straight up and fit best into the well. One tip--It doesn't take much pressure; you can feel a little "tick" when it's enough. This superb tool proves that you get what you pay for.Added tip--the amount you strip off the wire is very critical. It should not be more than about 2-3 mm. If you insert more than this into the connector for the first (wire) crimp the end of the wire can extend into the socket, and may block full entry of a mating pin, resulting in a loose, probably non-functional connection.

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

j'avais l'habitude d'utiliser une Plato SN-02B qui sertissait du molex proprement, en une seule passe (mors d'isolant et de conducteur). Mais le sertissage des broches Dupont nécessitait un doigté et un réglage de profondeur très délicat et minutieux, sous peine d'écraser l'intégralité du connecteurAvec cette pince, de bien meilleure qualité que ma SN-02B Chinoise, il faut effectuer deux sertissage distincts, l'un pour le conducteur, l'autre pour l'isolant. Mais la lame est assez étroite pour ne pas risquer d'abimer le fût du connecteur Dupont femelle (idem pour les VH et NH). Et accessoirement, la pince donne d'excellents résultats sur les petits modèles de cosses faston. La ferule du connecteur s'enroule proprement, comme elle le ferait avec une véritable pince Molex (laquelle coûte 4 à 6 fois plus cher).Mors en acier forgé et non estampés en série, poignée en élastomère, agréable à la main (les photos sur le Web laissent penser à un plastique de mauvaise qualité, ce n'est absolument pas le cas) ressort de rappel (en compression) un peu mou qui demande à être "étiré" avant la première utilisation. Si cette pince est utilisée avec soin pour ne sertir QUE des connecteurs électroniques genre molex ou dupont, sa durée de vie sera... largement supérieure à celle de son utilisateur.

This product is simple and it is not luxurious and it does not shout "precision!", but it is well-made and finished and the jaws mate together properly. The handle has detailing on it that must have been inspired by a Gundam - maybe not the most comfortable handle if you are going to crimp 1000 connections in a day. There are multiple sets of crimp jaws for crimping various kinds of terminals to wire. Like every other ENGINEER tool I have, it just works. Not sure what else there is to say? I am really happy I bought this after the more fancy ratcheting crimper I bought completely disappointed. You don't need a ratchet - your hands are easily strong enough to crimp these little connectors in one go, and getting a ratchet to release so you can clear the tool when the tool has messed up the crimp is so annoying. Perhaps if you're on a billion dollar contract you should buy the genuine Molex branded crimpers, a specific tool for each individual part number, and perhaps they would be better but at the price I will never know. Wish I had bought these a long time ago. (Crimping tip - wires with soft insulation, like PVC, crimp well. Wires with harder insulation like PTFE crimp better if the conductor part of the wire is stripped first.)

Nach langen suchen nach einer günstigen und guten Crimpzange, habe ich mich für eine Engineer der PA Serie entschieden. Die kosten zwar immer noch ca 40-50€, aber wenn man die Kontakte sauber Crimpen möchte, wüsste ich jetzt keine günstigere Alternative. Denn umso kleiner die Kontakte, umso präziser muss die Crimpzange arbeiten. Und das macht die, in meinem Fall, PA-20, wirklich klasse.Allerdings sind 2 Arbeitsschritte notwendig, zuerst für den Drahtcrimp danach für den Isolationscrimp. Doch für den Heimwerkerbereich sehe ich das nicht als Nachteil, sondern eher als Vorteil, da man so das Werkzeug vielseitiger für verschiedene Crimpkontakte nutzen kann.Ebenso muss man auch das Gewicht der Zange hervorheben, denn es macht schon einen riesigen unterschied ob mit ca.150g der PA, oder mit min.300g einer aufwendigeren Quetschzange in der Hand gearbeitet wird.Schwer empfand ich die Vergleichbarkeit der Zangen, mit der Produktbeschreibung auf der Engineer Homepage, bezüglich verwendbarer Crimpgrößen/kontakte und Kabelquerschnitte, da gleiche Crimpweiten wohl nicht für gleiche Kontakt u. Kabelgrößen gelten,?.Nachdem ich mit der PA-20, nun einige Zeit gearbeitet habe, kann ich nur sagen, ich bin mit den Ergebnissen sehr zufrieden. Mein Fazit lautet, eine sehr gut verarbeitete, leichte, sauber arbeitende, universal einsetzbare und relativ günstige Crimpzange.
