What is BS EN 61076-2-103 - Specifications for multipole connectors about? 
Electrical connectors are used to join electrical conductors to create an electrical circuit. BS EN 61076-2-103 is a part of an international multi-series standard that focuses on aspects of connectors for electronic equipment. BS EN 61076-2-103 applies to a range of circular multi-pole connectors with or without a latching device, having a nominal outer shell diameter of 19 mm, with 3 to 7 contacts (type ‘XLR’).
Fixed connectors are available in both panel-mounting and printed-board mounting versions.
These connectors are widely used in professional audio applications. BS EN 61076-2-103 establishes uniform specifications, type testing requirements and quality assessment procedures for a subfamily of circular connectors. It should be used in conjunction with the applicable sectional specification, see 1.1 of IEC 61076-2.
