Hello,
I did recover the remote control and the IR receivers from an Epson EMP7100 videoprojector (for future use...)
But I have no informations about the receivers ! (I didn't find anything on the web  :~)
Can you help me identifying them ? (see attached files)
Thanks
Jacques
just keep it, it can be useful one day ...

They are standard 38KHz demodulated receivers.

On the last picture, the two rightmost pins are the signal and VCC. The top track going directly to the connector is signal, the lower one that is buffered by C300, is VCC 3 or 5V.

The two leftmost is GND.
