What is a CNY70 sensor? The main problem is that I don’t understand much from the CNY70’s datasheet.
Vishay – Optical Sensors – CNY70 – Reflective Optical Sensor with Transistor Output
I couldn’t find anything about the ON state resistance of the transistor, which could make things much easier for me. I know this because I have used them occasionally since long long long ago and they do work. The relevant curves from the datasheet specified with a known reflectance are below:.

CNY70 product information
It’s more like a current source until Vce drops to below a volt or so. Using it to turn on an external output transistor fspaol give a vastly better result. Sign up using Facebook. Please contact authorized Vishay personnel to obtain written terms and conditions regarding products designed for such applications. For definitions of compliance please see www. Wish I could have enough reputation to upvote. Email Required, but never shown. The CNY70 is a reflective sensor that includes an infrared.
Such statements are not binding statements about the suitability of products for a particular application. How did you hook it up?
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. Sign up using Facebook.
Today with your help, I learned that there are photoresistors around and work quite different than bipolar transistors: SoajanII espaool 1 6. Please provide a schematic for this purpose Link to datasheet: The transistor will bottom out at mV or so. For definitions of compliance.
