A sensor detects the absolute angular position of a rotatable clamp arm between full opened and full closed positions. The sensor is coupled to a clamp arm pivot shaft to provide output signals corresponding to the absolute position of the clamp arm. One or more programmable angular position set points are setable at angular positions in advance of the full open and full closed positions of the clamp arm. Outputs are generated when the clamp arm reaches and/or exceeds each set point.
