As of August 2018 the State of California has changed the requirements of the “Prop 65” law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.
As an example: ABS plastic contains styrene PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP) electrolytic capacitors can contain Ethylene glycol Brass can contain Lead flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA) Aluminum alloys can contain Chromium To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching! |

Really a good part | |
| This is a part. If it works well depends how it is used. I used this to build a wheel encoder. I was prepared to design a circuit to detect a pulse. But I found I got text-book TTL level square waves right off the bare device using only a 4.7K pull up resister on the transistor. The IR diode runs fine at 5V with a 330R current limiting resister. It works well in high ambient light, although I shade it from direct sunlight. The diode side is marked with a diode symbol, the other is not marked so you have to guess which lead is the emitter. Test this yourself, but I found current flows in the transistor in the opposite direction it does in the diode. It is likely a photo-darlington. | ||
