interfacing Sensor with 9V input to Arduino

Hi,

typically sensor voltage range is from 0V to 5V, but I need to implement inductive proximity sensor where minimum input voltage is 6V. Is anyone here know how to interface such sensor with arduino? because the output signal is 6V if the input is supplied with 6V. I need some circuitry advice if possible, Thanks!

Best Regards.

Two 5K resistors in series from sensor to Gnd, take voltage from junction into analog input pin.
