Sensor device for generation of a control signal from the relative position of two motor vehicle components that move relative to each other has accuracy increased by use of a varying gap between moving control member and magnets

摘要

Sensor device (10) comprises two magnets arranged parallel to each other with a control member (55) between them. Field lines from the magnets extend through sensors, at least part of the control member and a gap (70) the width of which changes as the control member moves relative to the fixed magnets.
