See if this helps you.

There is some additional stuff that you don't need.

Or 5v or 24v or other.
Personally, I ordered a power supply from Antek with:
56V tap for steppers
12V tap for prox circuit
5v tap for laser, led's

I have a toroid trans output of about 30V and 9V/1A

can I use the 9v for pmdx-122 and prox?

Most Prox are 12v/24v but to vary. For instance, you can order a version that is 10vdc-30vdc allowable. 9v might be low for the sensor to activate and sense properly.

hmm,
Then, without complicating remains (repeatedly presented)

DC Switching Power Supply,
Slim-line,
DIN-rail mount,
Plastic Case,
12V/4.2A Output,
85-264VAC Input

Do you agree?

4.2A (50VA)is too big... you can save easily 50% if you go for a 2A SMPS which is still too much capacity for just 3 proxy switches. If I remember off the back of my head, each swith is 200mA & a3x200ma=0.6A double safty factor (which is already way too much for such application) is 1.2A & triple the safety factor is 1.8A... Why don't you save the difference in price to get a 6-pack?
