Connector suggestions - motors and probes

[GND]

Just wondered what types of electrical connectors people like to use on their machines?

I'm currently rigging up a Z-axis probe, and so want something that is reliable and latched so that it won't come adrift without me noticing. I'm thinking an XLR type connector could be appropriate, but I thought I'd cast the net out to see what forum members use more generally on their machines for the motor drives, limit/home switches and probes. Or is hard wiring preferred?

Looking forward to hearing any thoughts!

Cheers

Hi Graeme,

I use hard wired for mine, less to come loose and cause problems 😁

My first build used 4 pin xlr's worked well.

There are some pretty heft stuff available in RS if you are inclined to spend.

May actually have some male and female 4 pin XLR's left over if you are interested.

I'm using XLR 4-pin for motor connections. Signal connections (limit switches, e-stop, touch plate, etc) use GX16, bought cheap from Aliexpress. That's (I believe) the same connector that the usual air- and water-cooled spindles use with a screwed locking ring for security. Just hold them over a box or tray when you try to refit the fiddly little screw on the side...

Hardwired. And buy yourself conductive tape from Aliexpress, so motor, limit switch and similar are properly grounded both sides

Thanks for the feedback, guys - some good suggestions there!

From this small sample it seems like there's no single solution, and that hardwiring is often chosen. I can certainly see why that might be a good approach. I suppose it depends on the circumstances.

In my case I am keen to have my touch plate detachable, but obviously there is no room for this connection to be unreliable, else cutter breakages will occur! Hence a good quality latching connector, if you have to use one at all, is essential. I now have a couple of options to investigate further!

Just curious, Boyan - how do you deploy your conductive tape? Would you mind elaborating?

I don't see any reason to do this, just what is the point

Limit switches and servo connection example. may be not "by the book" as it must be using collars bolted to frame, but works fine

Thanks Boyan - so essentially shielding?

If you're just talking about a touch plate why not use 4mm banana plugs? That way the wire can be fixed and put out the way and then plugged in to the plate (or corner plate)
