One of the secrets of the extraordinary precision of Hexis, which permits to recognize coins in standard conditions at first insertion, lies in its new Caesium Pro validator module.

Traditionally the coin validators measure different parameters or features of coins: one of the most important has always been the electromagnetic analysis of alloys. Another main operation is the measurement of the coin diameter, in the validators designed by Azkoyen Group, instead, another parameter which permits to contrast the different types of fraud comes from the sound analysis.

The main innovation of Caesium Pro module is the collection of information on the metallic and magnetic composition of the coins with three different depths of penetration: three different wavelengths are used at the same time in order to get a higher quantity of information. Therefore the new coin analysis sensor integrates the advantages of the multimodal technology already patented by Azkoyen, which permits to the three detection coils to work at the same time with the processing and the multifrequency stimulation.

Furthermore, Caesium Pro validator module incorporates a new faster and more powerful microcontroller which permits a higher number of readings during the coin passage and a higher precision for each of the magnetic measurement parameters.

This innovative technology, covered by two new patents, involves a better quality of coin identification by Hexis Change-giver Coin mechanism, whose result is a better acceptance and, moreover, a better counterfeit discrimination and the fraud attempts.
