1. A non-contact sensor system, comprising:

  • a first sensor element;

    a rotary member disposed proximate the first sensor element without physically contacting the first sensor element, wherein the rotary member is configured to be rotated about an axis Y by a shaft configured to pass through the rotary member along the axis Y; and

    a second sensor element disposed on the rotary member proximate the first sensor element without physically contacting the first sensor element, wherein the first sensor element and the second sensor element are operatively coupled to facilitate sensing a displacement value X, wherein the displacement value X represents displacement parallel with the axis Y,wherein the rotary member is configured to interface with a wear pin, and wherein the wear pin comprises a channel configured to facilitate rotation of the rotary member about the axis Y, in response to the wear pin moving through the rotary member along the axis Y.
