Supporting wire gauges from AWG32 to AWG18, these tools feature an open-barrel design with higher lug height capability for superior pin curling. Trusted by professionals for their durability and accuracy, they provide vendor-quality crimps at a competitive price, making them essential for any serious electronics or DIY enthusiast. ## Description From the manufacturer ENGINEER PA-09 Crimping Tool with Super Precise Crimping Dies -- Crimp Open Barrel Contacts with a neat & professional finish! The ENGINEER crimping pliers facilitiate the crimping of the conductor part of the pin and the insulating part of the pin individually/separately (therefore two crimping actions per pin) , this allows the user to finely adjust the crimping force applied to suit (for example, more force applied when crimping the conductor, with less force applied on delicate insulation). Additionally, this type of crimping arrangement allows the pliers to be more adaptable & versatile, thereby resulting in these pliers being able to crimp many different pin variants across several Manufacturers' pin products. Operation & Features Step 1. Use the jaws at the tip of the pliers to slightly pinch in the lugs of the pin so they are parallel - like a U profile (when supplied the pins typically have more of a V profile) Step 2. Crimp the conductor part of the pin first. Establish the most appropriate die size for your pin (the pin should fit into the die neatly), then apply sufficient grip force so that the pin's lugs crimp firmly & securely onto the conductor wire. Step 3 Now, crimp the insulator part of the pin. Once again, establish the most appropriate die for this part of your pin, then apply the appropriate amount of grip force so that the pin's lugs crimp securely onto the insulation. (the precisely engineered crimp dies will safely 'roll' the crimp pin lugs onto the insulation) Spiral Spring & Locking Mechanism The ENGINEER crimping pliers have spring grips and a locking latch mechanism to keep the jaws closed when not in use (for safe storage) ENGINEER PA-09 SPECIFICATION ENGINEER PA-21 Crimping Tool with Super Precise Crimping Dies - Crimp Open Barrel Contacts with a neat & professional finish!

(when supplied the pins typically have more of a V profile) Crimp the conductor part of the pin first. Establish the most appropriate die size for your pin (the pin should fit into the die neatly), then apply sufficient grip force so that the pin's lugs crimp down firmly & securely onto the conductor wire. Step 3. Now, crimp the rearmost (insulator) part of the pin. Once again, establish the most suitable die for this part of your pin, then apply an appropriate amount of grip force so that the pin's lugs crimp securely onto the insulation. (the precisely engineered crimp dies will safely 'roll' the crimp pin lugs onto the insulation) The PA-21 works with pins that have longer lugs The ENGINEER PA-21 can also successfully crimp terminal pins that have longer type lugs.

It is not a single stage crimper. I find it best to crimp the conductor first then the insulation. **Q: Will this crimp tool crimp connectors for the jst ach type connectors?** A: Having researched jst ach type connectors it is evident that the PA-09 crimp tool is suitable. **Q: Will they work with jst sm connectors?** A: With practise I think yes. I have found them excellent for the price. Very small connectors are difficult unless you pay out for crimper many hundreds of pounds. Had cheaper crimper but they all went in the bin. Buy the best you can afford! ## Frequently Bought Together - ENGINEER PA-09 Super-Precise Crimping Tool & PA-21 (Made in Japan) Open-Barrel Crimping Pliers Featuring Higher Crimp Lug Height Capability (lugs) - Compact Precision Compact Long Nose Pliers (Needle tip),Professional Grade, ESD Safe with Carbon Steel Jaws.
