OMRON informatio source ?

Hi,

I jsut got a few OMRON sensors, different types and cannot find
installation and wiring diagrams, nor technical data sheets.

I have an Omron E3F2-3lZ photoelectric switch. 24V to 240 V two
wire.

I am not sure what is does. If it needs a remote source of light or
what.

I didn't bring the othes home so I don't have those part numbers.
some are switches, some are capacitive proximity sensors.

can anyone point me to a URL that might have these data sheets ?

Google turned up nice sales ads and other model numbers that are
probably more current. I can't keep pulling my hair out, the
reflection is starting to annoy pilots.
