ENGINEER PA-20 Universal Crimping Tool (Made in Japan) for AWG28-18 Open-Barrel JST XH, NH, VH Series, MOLEX KK, Micro-Fit Series, TE Mate-N-LOK, etc, Orange

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.

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 connecteur Avec 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.)
