how to wire tip ring and sleeve for sensors

[crouchorama]

HI
I am using phono stereo 6.5mm connectors for various sensors on my home built CNC machine. I would like to know if there is a good or bad way of wiring 5 volt power through the connectors.
at the moment I am using sleeve for shield /negative, the ring for signal and am using the tip for +5 volts.
Does anybody have some advice here.
Thanks
me

dont do it, when plugging/unpluging  the tip often  makes  contact with the other connections

"Generally" if you are only using microswitches you should be ok from an electrical noise point of view but shielded to ground (not negative of a PS) and wires up the middle (negative, positive and signal for proximity sensors if you are using them)  is what you should be doing. That said if it is a small one like a 3018 (small DC spindle) or a 3D printer then don't stress to much about the shielding.

If you want to use connectors then DIN style (metal bodied) would be a much better alternate over the 6.5mm and as in the previous post no chance of getting a contact you don't expect when plugging in or out. I picked up a used 6090 Chinese router a few months ago WITHOUT limit switches  and it came with empty holes on the case so I will be doing the DIN thing in the back of the box when I get to it. While I have some spare proximity switches more likely I will just go with longer lever type micro switches on this one.

I might consider putting some copper sleeve I have left in stock over the Spandle  wires to ground as the cheap and cheerful inverter is bound to be noisey.

"Spandle"? I love it!
Nice connectors, but not DIN though (yours are better). I know them from CB radio microphones etc., but am unsure of the correct name. EDIT: common term seems to be GX16.
Can be recommended, robust and with very good strain relief.

BTW, it's 6.35 mm or 1/4" phone jacks, not 6.5 mm.

inverter? so there's three phase AC at ~240V on a male connector?

Din for the Sensors as they are easy to get the others were just what it came with. I have a small stack of the plastic connectors below I really like too from other jobs so I might use them yet.  AliX Link

So many small dumb things on this one but I got it really cheap and it will finish up as a small Plasma Cutting Table rather than a Router including internally disconnecting the Inverter.

A higher quality alternative to those DIN connectors would be what is commonly called the XLR series of power connectors. These are the ones where the three pin version is frequently used for professional audio, but they are actually power connectors and there at least are four and five pin versions easily available. They have a push-button style latch and would be less susceptible to coming lose due to vibration.

XLRs are nice, but also much chunkier.
