The general trend of miniaturization leads to PCBs with more and more functions on the board, as well as different kinds of connectors. Using just one connector fulfilling all the technical demand could reduce the needed PCB space. For that, har-modular® is a preferred solution that can be used in applications where different kinds of signal, power, and data needs to be transferred from PCB to PCB. It can save space in replacement of different single connectors.
