I have a number of Intellitron (and MFJ) digital SWR/Power meters that use a very small pin coxial power connector. They are so small that the center pin (+) does NOT make connection to industry standard sizes (even most MFJ) power plugs. There is NO plug size shown in the manuals for these devices : WM1001D, WM-1002A, WM-1004A or WM-1005D. You have a special power cord shown as a 2.1mm coaxial connector to Power Pole DC Power cord. (SKU-Z12-DC-21-PP) does this power cable properly fit the listed Intellitron meters ?
Yes, that power cable is our recommended power cable for the Intellitron WM 1002a SWR meter and the WM 1001D. So the answer is yes, that cable connector is used for Intellitron SWR meters. That connector is widely used, but as you note that it is a 2.1mm connector.

My fear is that the center pin is sooo small in diameter that it won’t actually make reliable contact in the plug body can you actually try one in the digital meter to make sure ?
