FIELD: personal use articles.
SUBSTANCE: invention relates to an ultrasonic converter module for an ultrasonic sensor for detection of valuable documents. The ultrasonic converter module contains at least one piezoelectric ultrasonic converter with electrical connective litz wires and a mounting module for retention of at least one such ultrasonic converter for mounting on a connective substrate; the mounting module has connective strips that are electrically connected to the connective litz wires of at least one ultrasonic converter and have contact surfaces that are designed so that the ultrasonic converter module to be mounted is installed onto the connective substrate surface where contact surfaces are positioned that correspond to the contact surfaces; the contract surfaces and the corresponding contact surfaces are solder-connected to each other.
EFFECT: improving accuracy of valuable documents review without detriment to sonic vibrations.
