For a new design, I’m looking for a wire-to-board connector similar to those found attached to the backup battery (CMOS) of my old ThinkPad T420s. Pictures can be found on Lenovo parts lookup: Select by part number, then search for 02K7078.
Ideally I want the cable preassembled with a length of say 50mm. On the board I want the counter part as SMD.
(Think these are quite common, just lazy… )
