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?

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.

If you use proximity sensors with the 7I76E, make sure you
select "PNP" type sensors
(NPN types require an external pullup resistor per sensor)

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.
