Prox sensors for plasma table - Advice needed

Yes, but a LOT cheaper, and i do not mean the price! Omron are good, like really good, like .....

Just to make sure I understand you correctly, the Omron model I linked to is (in your opinion) a good product at a good price?

Lets put it this way:
If i could find them locally any time i need them, i would not bother to think about the price.
Just the time wasted to get the parts here costs me much more.

Ok, I get what you are saying.

There are quite a few options, sort of makes my head spin. What sort of sensing distance am I looking for?

Would you go with the plug in model, or a short pig tail that you would splice?

select "PNP" type sensors

(NPN types require an external pullup resistor per sensor)

Can you explain this further? I am certain I have NPN prox sensors on my 7i76 (not Ethernet). NBN8-12GM50-E0-V1 Pepperl Fuchs to be specific. But I don’t use resistors. They seem to work. Just want to make sure I didn’t wire them wrong.

Unrelated to your question... what type of connectors and wire are you using on your sensors?

Thanks

I bought the cables and female panel mounts here:

www.avidcnc.com/proximity-sensors-c-48_6...det8ueuj58p09qjifl67

I did not buy the sensors there. I actually got them used on eBay for a steal.

Sweet! Are you using the field wireable connector at all?

Thanks

I’m not sure I follow what you mean?

Checked my notes from my original build and PCW suggested then to use a 2.2K 1 W resistor which worked from me. Connect from the +24V wire and the output wire.
