These are 3-pin male-contact PCB-mounting connectors in a Neutrik A series housing, which mate with the Phoenix 3-pin screw terminal block connector. They have the same PCB footprint as the Neutrik A series XLR, allowing them to be used on PCBs laid out for XLR types.
NC3MAFH-PH has a PCB footprint that corresponds to XLR NC3FAH. NC3MAMH has a PCB footprint that corresponds to XLR NC3MAH.
Suitable mating Phoenix connector is stock code 43-495.
