Ultrasonic transducer help

Dear Friends

I am working on the Ultrasonic Transducers.

i am not able to understand the Voltage given in the datasheet.

what will be affect on my boards.
Pls suggest.

Thanks
marx

i am attaching snapshot of same.

It says 140 V peak to peak, this is 50V rms. maximum rating?

To get max power out of the device, you will have to excite it with an AC wave of 140V peak to peak (see post #2) at 40kHz. The output power has not been specified. It may be wise to reduce the max voltage by about 20% to leave some headroom. That will reduce the output power but that will depend on the nature of the coupling.
