DPU1440C01-L85

RYD DPU1440C01-L85 is a Ø14x9mm ultrasonic transducer with a center frequency of 401.0kHz, built for fast-response sensing. Its decay time of 1.2ms or less lets the element ring down quickly after each transmit pulse, which shortens the measurement cycle and supports closer working distances, while an asymmetric directivity of about 120° on the X-axis and 60° on the Y-axis shapes the acoustic field to fit elongated detection zones. The element operates from -30℃ to +80℃ and accepts a maximum input of 140Vp-p, fitting presence sensing, level and proximity detection designs that benefit from a tailored beam and quick echo recovery. Customization available: cable and connection method, drive adaptation and protective treatment can be discussed per your system; new designs can be developed for volume projects. Target scenarios: smart home appliances, industrial equipment, IoT terminals and consumer electronics.
