Dacă nu mă înșel,acest optocuplor este compus practic dintr-un LED clasic și un fototranzistor,într-o "cutiuță" oarecum demontabilă.Și dacă-mi aduc aminte(am avut o dată probleme cu așa ceva)l-am realizat dintr-un LED roșu și un BC107,la care i-am pilit "căciulița". Iar mecanic,le-am așezat față-n față,într-o bucățică de tubuleț negru.
