Hi,

Please ignore my previous post, I unfortunately hit "send" way too
early.

Ok,

to gain the speed of a Motor I'm looking for a realy small
"reflection-ligth-barrier" ( this term may be translated in a wrong way
). The part I've already used is a SFH 610. Now I'm looking for someting
similar but in a different case if possible.

I'm looking for a device which is available in a 3mm diameter round
shape.
e.g. like a two color 3mm LED.

Distance to the surfact which is "detected" for being there or not is
approx 5mm.

Ideas ?

Kind regards,

        Stefan
