A170W1 170 kHz Air transducer
P/N: H2KA170KW1CD00

A170W1 ultrasonic transducer works as a signal transmitting and receiving unit. This ultrasonic transducer is suitable for web guiding, double feed detection, banknote fitness, and proximity measurement, etc. Particularly, the transducer can transmit relatively uniform sound intensity, which results in good proportional band as wide as 28 mm (±14 mm).
