#electronics #connectors #crimping The Voron Community has a lot of recommendations for what to use for micro-terminals (JST, MicroFit3, Molex, Dupont Connectors, etc): @Steve_Builds: "For the most part, for what I have to crimp anyway, the Iwiss 2820M for everything but Duponts. Then I use the Iwiss SN-025." ## Ferrules [Wago's Specifications for Ferrules](https://www.wago.com/global/building-technology/electrical-installers/helpful-tips/ferrules?utm_source=chatgpt.com) Wago seems to prefer a square crimp ferrule (and with a gas-tight tool like their variocrimp tool): [Crimp-Zange Variocrimp 4 (206-1204) \| WAGO](https://www.wago.com/de/werkzeuge/crimp-zange-variocrimp-4/p/206-1204#details) ![[Pasted image 20260105135542.png]] My take? I probably would not run high amperage mains wiring through a ferrule covered wire in a Wago. There is a lot of anecdotal reports of burnted up connections. There's plenty of debate as to 4 or 6 jaw ferrule crimpers. It probably doesn't really matter. The [IWISS iCrimp](https://amzn.to/49bGVTY) is a great inexpensive option. The [Knipex](https://amzn.to/3YLy3zL) are amazing, but crazy expensive. **pro tip 1:** use the smallest possible ferrule that can fit on the wire. **pro tip 2:** disable the spring for the ratcheting mechanism and compress the ferrules by feel. often, if using the ratcheting mechamism, too much force is used on small ferrules and the tool just destroys them / cuts through them. ## Duponts - [IWISS SN-025](https://amzn.to/47eLyNR) ![[Pasted image 20250802143759.png|500]] ![[Pasted image 20250802143812.png|500]] ## JST, Tyco, MicroFit3, etc: - [ENGINEER PA-09](https://amzn.to/41psYid) - Japanese made is VERY good -- extremely similar to IWISS 2820M - [IWISS 2820M](https://amzn.to/40J83Xm) ![[Pasted image 20250802143934.png|500]] ![[Pasted image 20250802143951.png|500]] ![[Pasted image 20250802143958.png|500]] ![[Pasted image 20250802144122.png|500]] ![[Pasted image 20250802144134.png|500]]
