5 volts max.
But you can still use this.
The instructions are on page 7 of the datasheet, use the 1st method: NPN (Sinking) Outputs.
Get yourself a power supply suitable to the sensor.
If it is 10 volts, you could also power the Arduino out of that, through the barrel jack.
Any way, connect the GNDs of the Arduino board and of that power supply.
Connect the blue and brown wire as shown in the manual.
The trick is to connect either the black (most probable what you want to do) or the white wire to your input pin.
Set that input pin as INPUT_PULLUP
The resistor drawn in the manual is now "generated" internally in the Arduino, but connected to its 5 volts.
That should work.
Now if your sensor is active, the level at the input pin will be LOW.
If it is inactive, it will be pulled HIGH by that internal PULLUP resistor.
