Using 24v+ & GND to power a part-present prox sensor.

Yes, I agree about the grounds. What about the commons / neutrals for 24VDC?

Unless the power is shared through the different units/panels then I would not run commons between them if not needed.

What are the consequences of doing such things? I don't want to experiment, haha, but maybe someone else has more experience than me ))

Potential short circuits shutting down the 24V power supplies or blowing fuses.

And, ina panel that the problem might not be in.

Better put the old lever limit switch back in.. nice and durable without that extra common wire nonsense

Why not just get a 2-wire proximity sensor ? They only cost a few dollars.



You can always drive an optical isolation relay in the panel with it if it is not compatible with your inputs.
