  • Mystery Neutrik Connector

    Has anyone seen this type before? Model No. NP2RCS. I can't see how to connect the shield/ground wire. There is no solder lug and the body is aluminum.
    I can't find the exact datasheet, looked at the Patent, still no clue. I have a few of these new in the package. Had them for years and don't remember where I got them.

    I guess I could drill and tap a hole for a lug, but I'm just curious.

    I see a slot in the inner sleeve. Is it possible that the ground wire goes through that and makes it's connection by just getting sandwiched in the threads of the cap that screws on?

      Or maybe the shield is folded over the end of the sleeve and is pushed against the body when the cap is tightened. I wouldn't trust that connection though.

        It's supposed to be nickel, not aluminum. Have you tried soldering to it?

          I can't solder to it. I think it's cast aluminum. It's fairly light weight. The barrel and tip are probably nickel plated same as any phone plug

            The shell is supposed to be nickel or nickel plated, not that it necessarily means you can solder to it.
            Attached is datasheet for it and for it's updated version. The newer x style has a tab. The older rcs type I could not find an assembly sheet for.

              The 2rcs is supposed to have a little tab, like the rx. Where the rx has it below the tip connection, the rcs is supposed to have it to the left of the tip connection.
              He mentions it in the comments section of the video.

                I can confirm that the 2 RCS plugs have NO solderable ground lugs/tabs (at least the two I once bought). The body is a single massive piece of metal (probably nickel plated cast zinc). It doesn't take soldering, tried different spots and extra flux. So I never used them. Also don't like the non-conductive plastic cap, which prevents complete shielding.

                  It's possible there was a manufacturing error and some were shipped around the world before it was discovered. I didn't buy mine from a dealer. I got them from a junk store or Ham Radio fleamarket or wherever.
                  Agree about the plastic cover, though they would be OK for speaker cables.

                    Yes, that's what I originally bought them for. But with high speaker currents I wouldn't want to rely on some press fit grounding.
                    So they are useless.

                      That's what I think too. I'm guessing maybe the rejects were liquidated and ended up on the market rather than being destroyed. In the video (post #7) you can make out the little tab he solders the shield to.
