In sewing machine connectors, the socket contacts shall be recessed so as to comply with the distances specified in clause 26. This dimension shall be equal, if possible, to the dimension specified on the standard sheet in IEC 60320-1 for a similar connector.
NOTE 2 A sewing machine connector with entry holes having a diameter or a width not exceeding 3 mm and recessed not less than 3 mm, as measured from the engagement face, is considered to be acceptable; see Standard Sheets C 1, C 5 and C 7 of IEC 60320-1.
NOTE 3 A more precise relationship between the dimensions of the entry hole and the distance from the socket contact to the engagement face is under consideration.
The internal length of the socket contact shall be such that the contact overlap between the socket contact and the corresponding pin of the sewing machine inlets is not less than 4 mm.
Additional subclause: (following 9.6):
9.101 Sewing machine couplers shall not be interchangeable with connectors or appliance inlets complying with the standard sheets in IEC 60320-1 nor with plugs or socket-outlets for household and similar purposes (e.g. those complying with IEC 60083).
12.1.3 Replacement:Rewirable sewing machine connectors shall have terminals which can accept flexible conductors having a nominal cross-sectional area of 0,75 mm2 and 1 mm2.For screw and studterminals the diameter D is 1 ,4 mm, see standard sheet C27 of IEC 60320-1.IEC 60320-2-1 pdf download.
