I can't remember the brand name, but it cost a couple hundred dollars.
#Sn 28b crimping tool professional
I used to have a professional grade crimper with several dies for various wire crimping needs. Reviewed in the United States 🇺🇸 on July 5, 2017 Also the ratchet can be released by that little lever on the short handle side that comes out when it engages as it is closed (incase it slips you Can back it off and maybe save the connector rather than hopelessly smash it) His process seemed to be a very good approach and likely more inline with the intended usage than "multi step" methods I saw being suggested, which on their own may work very well too. I found a very good video over at youtube titled "Using IWISS SN-28B Crimper" which is virtually the same tool, but if you watch it note that the dies (crimp head) are installed in reverse on his tool compared to the Glarks model I received today. See in the pictures as assembled and in the one with the Red one I did beside a factory done one on a white wire.
The two crimps I did to test the process and tool both worked perfectly. Also putting them in upside down or not aligning them properly would easily wreck them. These are small and delicate connectors and a hefty tool with enough force to wreck them if you over do it. I carefully used pliers to narrow it back. It seemed best "not" push as hard as you can, just go until it barely releases the ratchet as to not smash the connector, even at that with the wire I used it was slightly wide from being crimped. The 2.54mm Dupoint is done in the smallest of the 3 sizes on the SN-28B marked on the one side as 0.25 and not the large one that is marked 1mm (I expect using too large a slot will overly flatten the connection or not end up with a tight enough crimp or both). While I have seen various uses of a "multistep crimp" approach where you do a partial crimp to get the shape easier to work with and even do the bare wire with one crimp and then the insulation section as another, it can be done in one step and I believe it was meant to. Based on what the connector specs are, you only strip 3mm of insulation.
#Sn 28b crimping tool manual
These connectors are designed for a machine to hold onto that back strip that you break the connector off of, and since you take it off to do the connections with a manual tool like this, it gets rater awkward. It is not a strait forward process with such small connectors, I looked at various tools listed of the SN-28B model (which is the proper tool for 2.54mm Dupont connectors), and all appear practically identical with very mixed reviews. I purchased this tool to make some 2.54mm Dupont cables. Reviewed in the United States on July 5, 2017
