What is BS EN 60130-9 - Circular connectors for sound equipment about? 
Electrical connectors are used to join electrical conductors to create an electrical circuit. BS EN 60130-9 is a part of an international multi-series standard that focuses on aspects of connectors for electronic equipment.
BS EN 60130-9 relates to circular connectors for radio and associated sound equipment. IEC 61076-2-106 specifies connectors with a similar mating interface for connectors M16x0,75 with screwlocking and degree of protection IP40 or IP65/IP67 and with M16x0,75 screw locking accessory. As the IEC 60130-9 connector styles mating with the corresponding ones of IEC 61076-2-106 do not have a locking mechanism specified, they are therefore not appropriate for industrial process measurement and control equipment.
Note: Users of IEC 60130-9 should be aware that some of the IEC 61076-2-106 styles could be mated but not locked to some connector styles of IEC 60130-9.

Why should you use BS EN 60130-9 - Circular connectors for sound equipment?
Electronic equipment is used in applications that rely on mechanical or electric systems for their operation. They are essential to any work on electronics systems for creating signals and capturing responses from electronic devices. There are certain specifications regarding the performance of electronic equipment. Electrical connectors are manufactured for power, data, and audio-visual applications. They can be differentiated by their specific method of connection, pinout, size, materials, contact resistance, mechanical durability, ingress protection, insulation and lifetime.
BS EN 60130-9 provides you with technical and dimensional information about circular connectors that depicts a clearer idea. BS EN 60130-9 discusses characteristics of circular connectors that help users to manufacture highly efficient electrical connectors. BS EN 60130-9 also provides you with a schedule for type tests to verify the performance characteristics of circular connectors which ensures their reliability.
The guidelines in BS EN 60130-9 help you specify circular connectors for sound equipment that enable you to provide a superior quality product to your customers.
What’s changed since the last update?
BS EN 60130-9:2011 supersedes EN 60130-9:2000. BS EN 60130-9:2011 includes some technical changes with respect to EN 60130-9:2000. These include: 
- The scope has been amended to clarify its separation through its field of application, from EN 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 EN 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 EN 60065 has been deleted.
