A combination for determining the relative positions between a first and second object, comprising: said first object having fixably mounted thereto an array of detectors along a defined detector array pattern, each of said detectors being constructed to output a logic unit “1”or “0”such that said output of said array of detectors produces a binary output; said second object being displaceable relative to said first object and having a generating portion aligned with said detector array pattern such that displacement of said second object causes said generating portion to displace correspondingly along said detector array pattern; said generating portion having generating means for causing said binary output of said array of detectors to change in a gray encoded manner with respect to successive changes in position of said generating portion of said second object; and, said detectors being Hall-Effect devices responsive to a magnetic field, and the generating means being a magnet divided up into plural North and South poles, wherein the detector array is fixed with equal center-to-center spacings, and the magnetic poles of said magnet have non-equal center-to-center spacings.
