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.

Seems to work as parking sensor
Purchase along with a 12 volt power supply and 12 volt LED strip.Wiring:12v+ > LED+12v+ > Both Brown Sensor Wires12v- > Both Blue Sensor WiresLED- > Black Sensor WireOperation:NO / When beam is broken (car parked), light is turned on

Garbage
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.
