hookup info?
are these parts polarized? how much current should they draw? can you hear/feel when one is emitting?
forgive the newbish questions, but this is my first time experimenting with ultrasonic transducers, and I'm having trouble measuring any coil resistance or current through the device @ 5v. thank you.

Is a datasheet out there?
I'd like to design this part in and having a datasheet on hand would be helpful. Is there one out there anywhere?

Any data sheet on the XDR-24? Can't locate.
The marking on the back side appears to be a Mitsubishi logo, but cannot find any reference to a data sheet on this item.

Anyone lucky enough to find one?

Excellent Experimental Sensor
These are excellent units. So much so I bought 30 of them for my robotics experimentation. They are extremely sharp, requiring a signal between 23.5 and 24.6khz. Units can be used as both receiver and transmitter. I set up a test rail, spacing two transducers 30cm apart. With a square wave of 5 volts fed into one transducer I read a signal of 60mv on the second transducer, used as a receiver.
In my application my receiver is an op amp with gain of 10 feeding an LM567 tone decoder. With 1.2 volts peak-to-peak, fed into the sending transducer, the tone decoder recogizes the signal at the distance of 1.5 meters, with the receiving transducer set at an angle of 45 degrees to the sender. These results assume some fine tuning of LM567 components

Good and inexpensive if you know how to use it
To answer the previous review, yes, these transducers are capable of both transmitting and receiving. I have constructed two ultrasonic rangefinders with these transducers, one uses a single transducer for transmit and receive while the other uses two - a dedicated transducer for tx and the other for rx. Both configurations require a rindown period although the single tranducer configuration requires a significant ringdown period before you can start receiving. I have been able to range large objects up to 9 feet away and as close as 1.5 inches with the dual-transducer configuration.
