I have a couple pcbs that will mate together with pin headers. I will have a 15mm standoff to separate these 2 boards. In my research it looks like the female pin header sockets seem to be about the same size and the male headers vary in length. I've looked at multiple female pin header spec sheets, but I haven't seen any that tell me how deep I can push in a male pin or how deep into the socket I need to push the pin in order to make a connection. I'm just trying to size my male header correctly.
Does anyone know? Or can you point me to a spec where you've seen that before?
