semi permanent screw terminals on enclosure

I'm using a Mega board and putting it in a small general purpose enclosure.

I would like to install something like the link... https://www.carltonbates.com/Through-Bulkhead-Blocks/PHOENIX-CONTACT/Through-Bulkhead-Terminal-Block-30A-600V-HDFK4/0707086/p/78037398891-1

Are there other/better options?

Have you looked at the online catalogues of large electronics suppliers like
DigiKey, Element14, etc?

How about a Mega Screw Shield? Available for worldwide shipping http://www.crossroadsfencing.com/BobuinoRev17/ |500x265

You're looking for a connector that you can mount on the side of the box (a "bulkhead" connector), right?

How many terminals and how many amps are you looking at?

Exactly. The I've checked the larger vendors that I'm aware of, and the product I linked to above is the only one I've found for bulkheads.

Maybe 10 connectors would be enough, but the idea is to build this thing so that I don't have to dork with it too much in the future. I would rather over build it now and never use the capacity...

It would be nice if I could run an automotive cooling fan with it... 40-50 amp / 12v would be the most I would put through it. most everything else would be 5-10v sensors, low current.

Perhaps you could arrange a choc-block connector strip to be trapped in
a slot in the case between the two rows of shrouded screw terminals:

Not all of them have much space between the rows like that one though…
They are at least cheap and available standard parts…

We use several different panel mount style connectors from automation direct. Basically you wire everything inside your cabinet to the panel bulkhead, then you make a wiring harness that plugs into that bulkhead. They come in many different pin configurations. Might want to double check the current rating though.
