Does a 96 ford Windstar have oil safety cut off sensor?

No, a 1996 Ford Windstar does not have an oil pressure safety cut-off sensor in the way that some modern vehicles do. While it has an oil pressure sending unit that feeds information to the gauge, this is primarily for monitoring purposes, not for automatically shutting off the engine. If the oil pressure drops significantly, the engine could suffer catastrophic damage before the gauge shows a problem, or even before the engine's internal components fail.
