4 pin slim din connector?

[lunacyworks]

Anyone recognize this connector?   I see there are companies calling it a slim din connector. It seems to be M5 size connector (similar to the M8/M12) style.  I see 4 pin versions that are similar but the Key is inverse or reversed.   This one was for a video cable.
