I think they call these "16mm aviation plugs" in the CNC machine tool world. They are common for connecting servo or stepper motors to their controllers.
they have any number of poles from 2 to 6 or more and screw rings that secure them. Usually really good quality even from Chinese eBay vendors. But they are really used only for a cable to chassis and only up to a few amps. here is one <http://www.ebay.com/itm/5pcs-Aviation-Plug-4-Pin-16mm-GX16-4-Metal-Male-Female-Panel-Connector-New/172271528592?_trksid=p2047675.c100009.m1982&_trkparms=aid%3D888007%26algo%3DDISC.MBE%26ao%3D1%26asc%3D44840%26meid%3D1f63ff61ed134f628c9629d26b2690b1%26pid%3D100009%26rk%3D1%26rkt%3D1%26sd%3D281469838889> Why so many connecter types? So you don't cross stuff up. Power poles are great for low-tech 12 volt buss systems that don't need any kind of engineering and are tolerant of connecting "anything to anything." Amateur radios and lead acid batteries are OK. Not good for high tech battery or their chargers or loads. Th XT60 or if you need 90 amps, the XT90 is ok because it is gendered and you can't accidentally connect two sources. The aviation type are perfect for cabling four or six lead motors. I would not use 3-pin XLR for anything but audio. Don't make it easy to connect line level audio to a battery. A really dumb idea was this guy, I heard this story secondhand. He used A/C extension cords for speaker cables because they work well for that purpose, but then someone plugged a speaker into a 120vac well outlet. I assume it made a load 60 Hz tone for a few cycles. Best to follow industry conventions because that is what people expect. Even though it would work well electrically, no one uses a mini-USB jack for Ethernet and for good reason On Thu, Jun 22, 2017 at 11:42 AM, Mark Spencer <[email protected]> wrote: > Sorry if I have caused any un due confusion thru my perhaps incorrect use of the terms "cannon" and "XLR." > The green connector with 4 separate female contacts is what I perhaps in correctly referred to as a "cannon" connector.
