Abstract
An example rotary actuator includes: a housing having a cavity therein; an output shaft disposed in the cavity and configured to rotate within the housing upon providing fluid flow within the housing; a cam coupled to the output shaft and configured to rotate therewith; and a rotary′ sensor mounted to the housing, wherein the rotary′ sensor interacts with the cam such that the rotary sensor provides sensor information indicating a rotary′ position of the cam and the output shaft.

A rotary actuator comprising:
- a housing having a cavity therein;
- an output shaft disposed in the cavity and configured to rotate within the housing upon providing fluid flow within the housing;
- a cam coupled to the output shaft and configured to rotate therewith;
- and
- a rotary sensor mounted to the housing, wherein the rotary sensor interacts with the cam such that the rotary sensor provides sensor information indicating a rotary position of the cam and the output shaft.

A method comprising:
- providing fluid flow to a rotary actuator, wherein the rotary actuator comprises:
- (i) a housing having a cavity therein, (ii) an output shaft disposed in the cavity, (iii) a cam coupled to the output shaft, and (iv) a rotary sensor mounted to the housing and comprising a follower extending into the cavity of the housing, contacting the cam;
- responsive to providing the fluid flow within the cavity of the housing of the rotary actuator, causing the output shaft to rotate, thereby causing the cam to rotate with the output shaft, such that rotation of the cam causes the follower to move linearly;
- determining, based on sensor information from the rotary sensor, a linear position of the follower;
- and
- determining, based on the linear position of the follower, a rotary position of the cam and the output shaft.
