DF40
The Hirose DF40 series comes in multiple pin counts — it’s not fixed.
They are fine-pitch board-to-board connectors (0.4 mm pitch) with versions starting from 10 pins all the way up to 100 pins (and even beyond, depending on the variant).
For example:
DF40C-10 → 10 pins (5 per side)
DF40C-40 → 40 pins (20 per side)
DF40C-100 → 100 pins (50 per side)
If you tell me your exact DF40 model number, I can tell you exactly how many pins it has.
