High Failure Rate
I ordered two of these Tx/Rx pairs. The first pair failed after two months. The transmitter had no output. I installed the spare transmitter, and then three months later the Receiver failed, indicating that the beam was constantly interrupted(which it wasn't). I replaced the Receiver, and the system was working again. After 6 months, this second Receiver quit. I did not buy any more of these items after the failure of one transmitter and two receivers in less that a year's time. Also, the output of the receiver is only a few hundred milliamps, so it really requires external voltage sensing circuit to drive a load larger than 200 mA.

This thing smoked as soon as I energized.

Burned out and smoked within a day.
We were only at the point of setting it up in the application when it smoked and burned out. Good timing really a day later could have burnt our business down.
