ABSTRACT:
A sensing device for monitoring the presence of a tool or other object on an automatic machine comprises a sensing head adapted to be mounted on the machine. The sensing head has a sensing needle mounted on the output shaft of a reversible motor actuated on each cycle of the automatic machine for movement through a swing angle such that the sensing needle will either contact the monitored object or complete the full swing angle movement resulting in a cycle continue or cycle stop signal to the automatic machine control. The swing angle is manually adjustable by a setting ring on the sensing head for either clockwise or counterclockwise initial rotation of the sensing needle through any desired angle up to 180.degree. degrees.
