Resumen (inglés):
IEC 60139-9:2011 relates to circular connectors for radio and associated sound equipment. This fourth edition cancels and replaces the third edition of IEC 60130-9, published in 2000, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- the scope has been amended to clarify its separation through its field of application, from IEC 61076-2-106;
- 8-pole connector styles 60130-9 IEC-22 through 60130-9 IEC-25 with screw locking have been deleted as obsolete and overlapping with some styles of IEC 61076-2-106;
- application and connections in Table 1 have been deleted because of referencing obsolete sound equipment. Titles of the dimension sheets and the clause headlines of Annex A have been amended accordingly;
- the reference to safety requirements according to IEC 60065 has been deleted.
