This part of IEC 601 30 relates to circular connectors for radio and associated sound equipment.
NOTE IEC 61 076-2-1 06 specifies connectors with a similar mating interface for connectors M1 6×0,75 with screw-locking and degree of protection IP40 or IP65/IP67 and with M1 6×0,75 screw-locking accessory. As the IEC 601 30-9 connector styles mating with the corresponding ones of IEC 61 076-2-1 06 do not have a locking mechanism specified they are therefore not appropriate for industrial process measurement and control equipment.Users of this IEC 601 30-9 standard should be aware that some of the IEC 61 076-2-1 06 styles could be mated but not locked to some connector styles of this IEC 601 30-9 standard.
