Title: Battery pogo connector temperature rating
Post by: hcglitte on May 27, 2020, 02:25:54 pm

Hi,
I'm going to use a pogo connector, originally intended as a battery connector, for connectivity between 2 boards.

The specs state it works down to -20 C.

In my design it must work down to -40 C.

I'm curious if the specs only says -20 C because batteries normally only operate down to this temperature. And that they don't care to test it below this level because its expensive to test, and not needed.

It's a rather simple part consisting of plastic and metal. I guess the plastic could crack at low temperatures perhaps?

Any experience here, anyone?

Maybe the pogo springs stop flexing at -21c ?

It's Bc‐11‐4pd in attached file.

So it's spring contacts. Not sure about the flex properties.

But a freeze spray may find this out.
