The angular and axial position sensor arrangement (10) comprises several sensors (S1, S2, S3, S4) arranged adjacently, and aligned parallel to the axis of an encoded member (20) that is angularly and axially displaceable relative to the sensors. The encoded member comprises N-1 axial detection encoded rings (21, 21', 21") with value A along their entire circumference and comprises an Nth axial detection encoded ring (22) that is axially adjacent with value B, different from value A, along its entire circumference. The values of axial detection encoded rings are distinguishable by the sensors overlapping some axial detection encoded rings. The encoded member comprises several angular detection encoded rings (23, 23', 23") axially adjacent to the Nth axial detection encoded ring. The angular detection encoded rings comprise a coding pattern composed of A and B values along their circumference to determine angular position by some sensors overlapping them. |
