SEN0554 Seems to die frequently for me

I have 3 of these sensors and two have seemed to suddenly die and no longer emit light when viewed through an IR viewer (the 3rd one still does). Is this a common issue and are these sensors really “dead”?

Yeah, this is quite common. If it's not emitting light anymore, it's highly likely it's dead.

Thank you! Do you have any suggestions for keeping them from dying as frequently?

Maybe the loose connection?

I have swapped the wires to the working one and every time it works so I don't think that is the case unfortunately.

If you're meticulously following this wiki but still getting erratic data then maybe the sensor has a fault.

I am looking at the sensor with an infrared viewer which lets me see the light from the emitter (and this works on the working one where I see the light, but on the dead ones they show no light.
