Is there any special requirements/limitations to how 100Mbps Ethernet conductors can be connected to the PCB?
For instance in the design prompting the question I have a Ethernet connection entering the enclosure via a M12 panel mount (4-pin, D-coded), on the other side of the M12 are 4 conductors - these conductors need to be connected to the PCB holding the Ethernet PHY.
Can I put them into the board via a screw/spring loaded terminal? should I solder directly? Are there special connectors for this purpose that I have not yet stumbled across?
