Claim:
1. A system, comprising: a first capacitive sensor disposed about a longitudinal axis and along a first axis radial to the longitudinal axis, wherein the first capacitive sensor is configured to transmit a first signal based at least in part on a first position of a face of a rotational component along the first axis relative to the longitudinal axis, wherein the rotational component comprises a shaft; a second capacitive sensor disposed about the longitudinal axis and along a second axis radial to the longitudinal axis, wherein the second axis is different from the first axis, and the second capacitive sensor is configured to transmit a second signal based at least in part on a second position of the face of the rotational component along the second axis relative to the longitudinal axis; a third capacitive sensor disposed about the longitudinal axis and along the first axis opposite to the first capacitive sensor, wherein the third capacitive sensor is configured to transmit a third signal based at least in part on a third position of the face of the rotational component along the first axis; and a fourth capacitive sensor disposed about the longitudinal axis and along the second axis opposite to the second capacitive sensor, wherein the fourth capacitive sensor is configured to transmit a fourth signal based at least in part on a fourth position of the face of the rotational component along the second axis.
