Proximity wiring for limit switches, safety relay and a contactor

[CharlieRam]

Can someone take a look at my quick sketch for proximity limit switche wiring please.

I have PNP NC switches so I believe I will need to wire in series for the limits to trigger. I want X, Y and Z all on one input for the Limits and I used normally closed as I believe they are safer as if a circuit is broken it will trigger the input.
Does the circuit look right?


For reference, this is how the AXBB_E manual shows to wire the PNP sensors in parallel but that is not suitable for normally closed switches.

Cheers,
Charlie
