I know I could use a 120v sensor with a contactor but I was looking for a single unit.
Does anyone make a 240v wall mount occupancy sensor?

Leviton does

It may only be single pole, though.

The instructions only illustrate a supply voltage of 120 to 277 with respect to neutral, and load connected line to neutral. The detector itself is powered by a connection to ground rather than neutral. This leaves wide open the question of whether it could handle a 240 split phase load or a single phase line to line load from three phase. (In other words, how far the return side of the load is allowed to deviate from ground, which could also be interpreted as K8MNZ's single versus multiple pole concern.)
The instructions also give an allowed load wattage or amperage and voltage for both incandescent and fluorescent. No spec for LEDs.
Incandescent loads are only allowed up to 120V.
