Reflective IR Sensor data sheet Product ID 2349

by nathan_fpa on Tue Aug 11, 2020 9:49 pm

Hi, recently purchased a couple of "Reflective Infrared IR Optical Sensor with 470 and 10K Resistors" PRODUCT ID: 2349.

I have pulled one apart and want to know if anyone knows the part numbers/data sheets for the the IR emitter/receiver within the housing?

Any help much appreciated.

No, I'm afraid we don't have any information except that it's a phototransistor.

Most photoransistors have roughly the same specs: maximum current is around 20mA, dark current is about 100nA, and they're normally operated in the 1mA range. The response time is in the 10us range.
