I would guess that most units are between dataseet. Reflective Optical Sensor with Transistor Output.
This indicates how much current the transistor should pass, for a given LED current. Show a schematic diagram. Wish I could have enough reputation to upvote. Xcodo 4 The graph below shows Iout for 20 mA Iin at various reflector distances.

The main problem is that I don’t understand much from the CNY70’s datasheet. I couldn’t find anything about the ON state resistance of the transistor, which could make things much easier for me Could you please explain what calculations should I do, or which figures should I check in the data sheet in order to calculate the X resistance value for safe operation. The relevant curves from the datasheet specified with a known reflectance are below:.
For technical questions, contact: Did you use Fig. When I connect Vcc and Gnd, I can be sure that catasheet transmitter works because cellphone camera detects it but it won’t turn on the LED in any case.
