Beschreibung
Zusammenfassung:	An ultrasonic sensor and method for using the same are arranged for capturing a value document transported through a capture region of the ultrasonic sensor. The ultrasonic sensor has an ultrasound transmitter arranged for emitting ultrasound into the capture region and an ultrasound receiver arranged for receiving ultrasound from the ultrasound transmitter from the capture region. A control and evaluation circuit is arranged for controlling the ultrasound transmitter and for capturing and evaluating the signals of the ultrasound receiver. A circuit carrier carries the control and evaluation circuit, the ultrasound transmitter, the ultrasound receiver, and conducting paths electrically connecting the control and evaluation circuit to the first and second ultrasonic transducers. The circuit carrier has a U-shaped configuration and two interconnected arm portions, and the ultrasound transmitter is held on one of the two arm portions and the ultrasound receiver on the other of the two arm portions.
