Hi.
I’ve seen that they call the sensors connector “DF13” which I found on Digikey and ordered a bunch of. But they seem to be misfit?
Are there different DF13 ?
@thorleif Those look right for a “through-hole” connector.
The more common rectangular DF13 connector is for a “surface mount” connector. 4 Position Surface Mount DF13 Connector
Thats so wierd, my connector does not fit, the “holes” back are for locking it my locking pins on my connector are closer together. See attached image:
Where did that header connector with the wires come from?
That doesn’t look like a DF13 header as all the real ones are tan or “natural” in color. You may have a PicoBlade header, what all the Chinese manufacturers like to use because they are cheaper.
Hey, you tell me? It is your temperature sensor, bought a few years ago. I do not get any i2c signal either 
it is the “super accurate” one, not the pressure and temp sensor. Thought all my sensors had these. Have you been changing them lately? Or bad batch? 
Aha, found the right connectors online and ordered a bunch of them so I can swap it 
Thanks for confirming that it was wrong, might also be someone changed it as I did not use them at the start.
The connector on those wires is not DF13, I think it was switched after it was received.
Thanks, christmas mystery solved!
Awaiting a bulk of DF13 connectors to swap to the right one.
