potential divider as signal conditioning

Hello DAQ experts.
I have digital sensor switching between 0 --> 12 V. I wish to feed this into a counter channel on a PCI DAQ which only supports +5V on the digital input. I was thinking of using a simple potential divider network (two resistors) to scale the signal down to 0 --> 5V.
Can anyone suggest if this may or may not be a good idea? If it isn't I would love to hear why not (analogue electronics is not my stongest skill
)
thanks
