    We chose the EMSA050300 adapter for 12v input for my project.
    So we can select the Connector PJ065A to the EMSA050300 adapter.
    Hence how can connect the PJ065A with my circuit board.
    Because we need to give the 12v from the adapter to LM2675-3.3(converter)IC in our circuit.
    The PJ065A has 3 Contacts in that schematic.
    Please can you give the description about the 3 contacts in PJ065A for me as earlier.


    Which one is connect to the VIN pin of LM2675?

    and What about another 2 pins?
