A new edition of IEC 61076-2-109 has been published by the International Electrotechnical Committee. IEC 61076-2-109 applies to “Connectors for electronic equipment – Product requirements – Part 2-109: Circular connectors – Detail specification for connectors with M 12 x 1 screw-locking, for data transmission frequencies up to 500 MHz.” The new edition is available for purchase on the IEC website.
“IEC 61076-2-109:2014 describes circular connectors with IP 65/IP 67 degree of protection and suitable for data transmission with frequencies up to 500 MHz. Applications include, but are not limited to, vision systems and data acquisition. These connectors consist of fixed and free connectors, either rewireable or non-rewireable, with M 12 x 1 screw-locking. Male connectors have round contacts ∅ 0,6 mm. This standard covers two different types of connectors, denominated X and H, with different contact arrangement, not mutually interchangeable, but with common ratings and purposes.”
