Have been Quiet lately of course everyone else has been to. Hope to Get back and start working on some upgrades, I have been wanting to upgrade my inductive Proximity sensors power. For as long as I have owned my 3D Printers I have operated all proximity sensors with a +5volt source. I plan to add a optical coupler then supply the correct operating voltage to my Omron TL-W3MC2 driving the correct +5volt for controller operation. Example shown below. Do not know if it will change the operation of my 3D Printers, as I believe they are barely outside the operating voltage level now.

Will be interesting to see your progress. I did not use an optocoupler when I had installed my inductive sensor on my old Ender 3 Pro, and I had the original z stop still connected to z stop and the probe connected to a dedicated port on SKR mini E3 board, which took a little figuring out in Marlin. But it did work well.

Have been busy the temperature was in the 60's in Washington State this weekend so though would get a jump start on spring yard work.
Will get back to this project soon.

Started looking for my optical couplers and have not located them, do not know when I put them.
Will continue looking though my have to repurchase.

I finally found the item I was looking for an of course it was in the last place I looked.
I got a thought that I put the optical sensor where I would have to look before needing it.
Well guess what, the coupler was in a place it should have never have been put because the location it was found in had nothing to do with the use.
it just finally snapped into my mind that this was the only box that I had not searched for the optical coupler.

Today I started working with this Optical Coupler and my TL-W3MC2 inductive proximity sensor.
However I find myself is somewhat of a dilemma. I wired according to the above layout, measured the signals and find no measurable signal from the TL-W3MC2. Thinking that this could be a bad TL-W3MC2 inductive sensor, then tried another Optical Coupler both with same results. When I measure TL-W3MC2 inductive sensor with a 12 volt supply alone the signal changes from 4.71volt to 5.87volts. I even tried to add both a pull-up and pull-down resistor to circuit.
Can someone help with a anything that I could try to fix this problem while using my TL-W3MC2 inductive sensors
The optical sensors work in on my 3D Printer with a 5 volt supply was wanting to test with a supply voltage closer the the working voltage of TL-W3MC2 inductive sensor.

do you need the coupler for a reason, or could you simply put a JST connector on the sensor and connect directly to your board?

The Proximity sensors has been operating at 5V for three years now. The operating voltage for this sensor is 12V. Have not had any major problems though thought if it was operating in the correct voltage range it would give better accuracy. An of course something to gather more information, learning and post about. Its been a long time sense being in a classroom and learning, this the forums is now my classroom learning centers. Though cannot give all credit to forums, You-Tube is one major contributing resource for my learning.
I found this circuit below an have a few breadboard components it an give it a go.
