| Decent DC power connectors that aren't barrel or powerpoles? |

Neutrik ones are rather interesting. Just about in budget. I looked at some Cinch ones that were similar to that but found they were discontinued. I had Molex ones on my FT450D - they were pretty good. Aware of the problems of misconnection. I walked into my local radio shop and someone had blown up their Yaesu thanks to a "polarity incident" :palm:. I haven't done that yet. In fact I'm so paranoid about it, I tend to DMM check everything before I plug it in several times. They are genuine ones from Torberry (UK distributor). I have been soldering them on as I don't have a crimp tool and I think this has caused some problems with contact alignment. Perhaps I should scrap this idea and stop being a cheap arse and just buy a crimp tool! I notice Torberry do booted ones which might help the strain issue as well: https://www.torberry.co.uk/product/powerpole-pack-red-black-cw-contacts-and-sleeves-1327-1327g6-13312 --- Quote from: sleemanj on May 29, 2019, 09:03:43 am --- --- Quote from: bd139 on May 28, 2019, 08:20:47 pm ---(XT30/60/90) Have discounted these as they're not latching. --- End quote --- Amass makes latching versions.... but even the standard unlatched type fit together very snugly, after all they are used in relatively high vibration models etc. I use XT60 for test leads, love the things, XT60-banana, XT60-alligator, XT60-testhook, XT60-wire, XT60-2xXT60 (parallel), XT60-XT60-XT60 (series), XT60-USB, XT60-Barrel, XT60M-XT60M, XT60F-XT60F.... and so on, so I can just plug together the ends to make up the right cable as needed. The connectors are even marked with a small embossed +/- so you can always be sure you're following the same "standard". --- End quote --- I'm liking that. Thanks for pointing me at these. |

Have you considered Rean Tiny XLR connectors? They are rated to just shy of 5A, with less than 10 mOhms resistance after 5000 mate-unmate cycles. Rean is an alternate for the original Tini Q-G parts from Switchcraft that include mating, male, PCB-mount receptacles. The wired connectors are limited to a maximum wire size of 24 AWG (0.22 mm^2). If you can live with that, they are fairly common, and not expensive for what they offer. |

My favourite DC power connectors are these: https://www.toby.co.uk/powertoboard-connectors/75-amp-cable-connectors/ |

There is a difference on whether the connectors will be included in a fixed panel or only just attached to the cables. These look like they would work: https://www.te.com/usa-en/product-350786-1.html |

Those Toby connectors are awful. They are on some laptops and on Synology NAS systems. They extend -a lot- away from the product. And do not offer good tactile feedback. Both correct and incorrect goes tough, and you must look to verify correct insertion depth and orientation. DC connectors are either expensive, or not very good. Or you're getting into very niche crimping products. Also, 5000 mating cycles is a lot. |
