Hi John, I don't need the component.....I've a loot of those components in all kind of sizes.
I only want to know if a opto is also a option to use ?
I think a hallsensor is not acurate enough, and thats also the problem with this designe and software we use.
I test some new hard and software and see the differend between a hallsensor and a optocoppler.
The opto trigger every turn in the same degree, a hallsensor depent on the rotation speed.
At low speed the magneticfeeld of the magnet is bigger the at high speed.
