Pivoted arms are often used for supporting a sensing transducer or head at a free end. Such sensing transducers can be of the sonic, optic, capacitive, conductive, electric field, or magnetic flux sensing type. A rotary actuator can pivot the arm about an axis for scanning the sensing head in the direction of double-headed arrow F. It is desired that the actuator be low cost, if possible, and that the head's movement for each actuation be predictable. This not only means that the actuator operation should be repetitive, but that any drag on the head arm should be consistent throughout the pivoting range of the arm.
