In an air feeder equipped with a movable clamper reciprocally driven by an air cylinder, magnetic parts and non-magnetic parts are alternately formed at equal pitches in the piston rod of the air cylinder, and a predetermined alternating current is applied. A sensor including a primary coil and a secondary coil magnetically coupled to the primary coil is provided in close proximity to the piston rod, and the output of the secondary coil corresponds to a change in magnetic resistance due to movement of the piston rod. A controller that includes a stroke detection means for calculating the stroke of the air cylinder through the controller, and stops the air cylinder when a preset stroke and an actual stroke of the air cylinder detected through the stroke detection means match. An air feeder feed length control device comprising:
