Single action: All original tools allow insertion of the contact and crimping in one go. What differences can I expect using original tools versus generic tools? There are thousands of generic crimp tools out there. Personally I would prefer they spent their efforts improving the mediocre results of their own designed crimp tools, rather than copying others.ĭo your own research too. Don’t expect it to be made to the same standard as the Hozan. IWISS have added an exact copy of this tool to their catalogue – IWS-1442L. It’s not a clear-cut winner however as it is more effort to use than the IWISS ratcheting tools and gets less consistent results, owing to the fact that crimping force is controlled by your hand. You can crimp both separately to whatever extent you require. This gets around another common problem with generic tools where these are combined, in that one may be under or over crimped. The above two features are combined in a tool which crimps conductor and insulation separately. It has two ‘O’ shaped crimping dies, something that is rarely seen on generic tools. Single hinge tools like the Engineer PA-XX models cannot achieve this unless one has an extremely strong grip, or the tool is compressed in a vice. Its compound hinge amplifies the crimping force, meaning you can have as much as you like, you can even crush the contact into two if you so desire. It has two features which many generic tools lack: It tends to cost around $70-80 and has to be ordered from Japan. I recently obtained a sample myself and can confirm that it’s a good option for those happy to spend a bit more. Several readers have written to me about this tool over the years – it’s generally well spoken of. Not as well made but for the significantly lower price, it could be forgiven.įor those with a little more to spend Hozan P-707 It is a little pricey but definitely wins for crimping smaller contacts i.e. Unlike the PA-09/21 its jaw is cleanly machined, allowing easy removal of contacts after crimping. Recommended if you work with larger contacts. Another good 4 die tool from IWISS, however all significantly larger than the SN-2549. It tends to apply too much force to the insulation part, but one cannot have it all on a budget. It crimps the conductor and insulation in a single action, with the ratchet double hinge mechanism providing good force on the conductor part. 
It has a cleanly machined jaw, so contacts won’t get stuck in it.
It’s good for most medium sized power connector families on this page i.e. My preferred budget tools: IWISS SN-2549 and Engineer PAD-11 On this page I’ll cover some of the most common connectors in use today, and detail crimping/tooling considerations.Įvery connector system ever conceived has its own official crimp tool, in most cases the cost of these is over and above what any hobbyist could and would want to pay for a crimp tool. With so many different types of connectors available, it’s often difficult to know what to buy, especially when you’re buying for general use and/or personal stock. Big sellers like Digi-key/Farnell/Mouser literally have tens of thousands of product lines in their connectors category! The range of connectors available and in-use today is trully astonishing. 187 FASTON – TE ConnectivityĪs someone who builds a lot of electrical things, one of the perhaps most unexciting yet fundamental subject areas is connectors.
