Units work as described. I do not se any difference between Rx and Tx in addition to the T and R marking. They both seem to perform the same as transmitters or receivers.The big ring on the transmitter pin does not mark polarity. If you are going to use transmitters in parallel you must measure the output and reverse the wiring if phases are reversed. You need an oscilloscope to test this.4* because of the random marking. Otherwise, no issues.

I hooked the up to a 3v 40Khz signal and the receiver put out 1v at a distance of .5 inches with no amplifier.

When paired with the proper IC in an appropriate circuit, these sensors work great.

I've sourced these elsewhere, and they all seem to be identical in quality, perhaps from the same source. The transmitters function well as receivers, also. I get the idea that they are the same, except for the marking.
