Yes it is possible with certain sensors, but I advise against it.

As stated before, to stop the cylinder's piston the pressure on bot sides of it must be equal. Air under pressure takes a finite time to move. That time is much longer than the processing cycle of the cRio.

Also, if the load on your piston changes, it will move. Air is a gas, and gasses are compressible. So asking the piston to stay on one place (even if you ask nicely) might not work.

There are other issues as well, but all are solvable. The question is, is it more effort to solve these issues or develop a design that doesn't have them in the first place? Only you can decide.
