Xpro V2 controller and proximity sensors

Hi and a happy new year to you all in the next few days.
As per title. I have xprov2 board and have just received some pnp proximity sensors. My question is do I need to change them for npn type or is there a way of using the ones I have with 5 volt input ? I understand that the limit port is normally pulled down to ground rather than the opposite which the pnp type of sensors do. Also the pnp sensors I have are the normally open type.
Best regards

Hi Gary and thanks for fast reply
Here is a link to the sensors

The same guy does sell the npn version but after reading and watching people on internet videos they say this one works at 5 volts rather than higher voltages which would be ideal for the xpro V2 board

I think I had seen this video but became a bit confused with thinking the probe pin setting $6=1 was for When using a probe to zero x y z with a probe plate. But I’m hoping this means I can invert $6 and the pnp sensors can be used to home my xyz axis’s. So in effect I will wire The same as second option posted by Michael in this thread and just change $6=1 in grbl settings?

Thanks for the video Gary. This is where I’m confused by grbl settings to use prox sensors

$5 - Limit pins invert, boolean
By default, the limit pins are held normally-high with the Arduino's internal pull-up resistor. When a limit pin is low, Grbl interprets this as triggered. For the opposite behavior, just invert the limit pins by typing $5=1. Disable with $5=0. You may need a power cycle to load the change.

NOTE: For more advanced usage, the internal pull-up resistor on the limit pins may be disabled in config.h.

$6 - Probe pin invert, boolean
By default, the probe pin is held normally-high with the Arduino's internal pull-up resistor. When the probe pin is low, Grbl interprets this as triggered. For the opposite behavior, just invert the probe pin by typing $6=1. Disable with $6=0. You may need a power cycle to load the change.
