Engineers Precision Crimping Pliers PA-09

I had few picoblades in my design. This crimp tool can handle picoblade connectors. It forms nice crimp. I was able to get reliable crimps in first attempt itself. This is not a sophisticated crimp tool like molex. however, with 1/5 the cost, I can achieve the crimp.

It’s a genuine Japan made product, perfect and easy to use

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

PA-20は所有していたのですが、小型端子の圧着が出来なかったため、今回PA-09を購入 日圧XH,PHに使っていますが今の所問題ないと感じます カタログでは 幅等が表記されていますが、それより先端の刃の薄さが重要 PA-20では刃の厚みが2.6mm、PA-09では1.8mmと細いので小型端子によく合う。 １点気になる所として、刃先のロック機構が扱いづらく なかなか開閉できない。PA-20の方がやりやすく感じるのでいつかは修正されることを期待する。 もう長年このタイプの圧着工具を使っているので慣れていますが、メーカー専用工具だと１種類しか対応できないのに高額で複数所持するのは無理です。このような汎用タイプは重宝しますので１本は持っていると安心でしょうか。

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.

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.
