400 kHz sensing for fish finding and depth sounding
The BBUA-F400K is an underwater ultrasonic transducer specified at a center frequency of 400 kHz ±5%. Its 0.3 to 40 m reference range supports fish detection and marine depth sounding over short and medium acoustic paths.
Operating envelope
The transducer is rated for operation from -40 to +80°C. The supplied data states a pressure limit of ≤10 kgf or 1 MPa and an IP68 protection rating for underwater integration.
