I have been struggling with this photointerrupter/coupler combination in my project, and somehow just can't get it to work the way I think it should work.
As interrupter I am using RPI-246 (link to PDF)
and for the coupler it is TLP117 (link to PDF)
Do I need a transistor after the interrupter's detector, in order to create a darlington pair? ... would that fix it?
It somehow looks like I just can't get the emitter on the coupler to light up bright enough in order to drive the gate on it.
Or, is there a flaw in my schematic?
Thank you for helping me out.
