alortegac Posted January 4, 2019 Share Posted January 4, 2019 (edited) These are both sides of the roller sensor. Can someone confirm what kind is it? Is it ir diode and phototransistor? What would the diagram be for this circuit/switch? thanks a lot! Al Edited January 4, 2019 by alortegac Quote Link to comment Share on other sites More sharing options...
ChildOfCv Posted January 4, 2019 Share Posted January 4, 2019 (edited) The one labeled "PT" is likely the phototransistors, and the side labled "IR" is likely the infrared LEDs. Also, this dude's project page has a picture of the schematic symbol. http://www.utopiamechanicus.com/article/arduino-photo-interruptor-slotted-optical-switch/ Edited January 4, 2019 by ChildOfCv Quote Link to comment Share on other sites More sharing options...
