Frequently Asked Questions

What is the operating voltage and current for this ultrasonic sensor?

The sensor is a passive piezoelectric transducer and does not have a fixed operating voltage. It requires an external driver circuit (typically an AC signal at 40kHz) to excite the element. The current draw depends entirely on the driving circuit's design and the applied voltage.

Can this sensor be used as both a transmitter and a receiver?

Yes, its open structure and piezoelectric design allow it to function as both a transmitter and receiver. However, for optimal performance in pulse-echo mode, impedance matching and dedicated driver/receiver circuits are recommended for the respective transmit and receive phases.

What is the beam angle or directivity pattern of this 40kHz transducer?

As a 16mm diameter piston source at 40kHz, it exhibits a moderately directional beam pattern. The exact beam angle is not specified but is typical for its size and frequency, providing a balance between directivity for targeted sensing and a wide enough cone for general detection applications.
