Frequently asked questions
What is the price of ITR9909 Reflective Infrared Photoelectric Switch Sensor 940nm in Egypt?
ITR9909 Reflective Infrared Photoelectric Switch Sensor 940nm currently costs 19.38 EGP in Egypt.
Where can I buy ITR9909 Reflective Infrared Photoelectric Switch Sensor 940nm in Egypt?
ITR9909 Reflective Infrared Photoelectric Switch Sensor 940nm is available from UGE. Compare the offers above to find the best price.
How do I connect this sensor to a microcontroller?
The output is an NPN phototransistor, so it is usually wired with a pull-up resistor on the output line, and the MCU reads the change in voltage level. The IR emitter needs a series current-limiting resistor. Verify the maximum ratings in the datasheet.
Will it detect any surface?
Detection depends on the surface's reflectivity and distance. Dark or matte surfaces reflect less infrared, so test with your actual target and mounting distance before finalizing the design.
