On about a 20x blowup of the pdf'd brochures page showing the pin names, it looks like this for a bottom view.
led end sensor end |-------------------------------| | K . .vcc | | 0 .vo 0 | | A . .gnd | |-------------------------------| And the footprint in the library has both + terminals on the same side. And its this ambiguity in the docs on this stuff that cost me the last 3 of a different type device about 18 months go when I was gung ho to do this then, and it all smoked in about 10 milliseconds when I applied 5 volts. The markings on the tops of the towers are of zero utility other than being marked with a + sign on opposite corners, and I presume the 3 or E on one end is the emitter end, and the 5 or S on the other towers top means sensor, it has 3 leads out the bottom at least. And that also corresponds with the rest of the outline drawings supplied with the HoneyWell HAO2001 slot sensor.
