  • Linear Motion Position Sensor and Method of Use
    Publication number: 20090097040
    Abstract: A linear motion sensing system for sensing at least shaft position of a linear moving shaft of a linear motion device includes a sensed structure associated with and moving linearly in unison with the linear moving shaft; a light sensor assembly including a light emitter emitting light directed at the sensed structure and a light detector receiving light from the light emitter, the light sensor assembly emitting signals indicative of at least position of the sensed structure; and a sensor module receiving the signals indicative of at least position of the sensed structure from the light sensor assembly and determining at least shaft position of the linear moving shaft of the linear motion device.
