Abstract (en)
Method for identifying disk-sheet metal parts having a central orifice by means of a selector which includes optical sensors (3, 4) and an electromagnetic sensor (5) consisting in obtaining and measuring characteristic values of the signal produced by the passage of the central orifice (2) of the coin (1) through the electromagnetic sensor (5) to obtain parameters which are representative of the existence and size of said hole, and the calculation of the length of the chord of the hole (2) intercepted by the optical sensors (3, 4). <IMAGE>
