Unictron’s A300A ultrasonic transducer is designed to deliver outstanding performance at around 300 kHz frequency. The transducer works as a signal transmitting and receiving unit. This ultrasonic transducer is particularly suitable for double feed detection, edge position control, splice detection, label detection, web guiding, banknote fitness detection and proximity measurement. It works reliably regardless of materials under detection, for example: paper, glass, transparent plastics, shiny metal, and cardboard. Please note to use the soldering tip to mount the transducer onto circuit boards. The transducer is not designed for reflow soldering process. Do not put the transducer in a reflow oven.
