Overview
IEC 61076-2-103:2004 is an international standard published by the International Electrotechnical Commission (IEC) that specifies detailed requirements for a range of multipole circular connectors, commonly known as type 'XLR'. These connectors, recognized by their nominal 19 mm outer shell diameter, can accommodate 3 to 7 contacts with or without a latching device. Serving as an essential subfamily under the broader IEC 61076-2 series, this standard establishes uniform specifications, type testing requirements, and quality assessment procedures crucial for electronic equipment connectivity. It is instrumental in ensuring connector performance, reliability, and interoperability in various electronic applications.
