IEC 61076-2-113:2017描述了具有两个数据对和额定电流高达12 A的电源触点的M12圆形连接器，通常用于工业场所的数据和电源应用。这些连接器包括固定连接器和自由连接器，可重新接线或不可重新接线，带有螺钉锁定。公接头的圆形触点直径分别为1.50 mm、1.00 mm和0.60 mm。 本文档提供的不同编码防止了相应编码的公连接器或母连接器与其他标准涵盖的任何其他类似尺寸的接口的配合以及本文档提供的不同编码之间的交叉配合。 M12是这些圆形连接器的螺钉锁定机构的螺纹尺寸。 关键词:连接器，圆形连接器，M12。

IEC 61076-2-113:2017 describes M12 circular connectors with two data pairs and power contacts with current ratings up to 12 A, that are typically used for data and power applications in industrial premises. These connectors consist of both fixed and free connectors either rewireable or non rewireable, with screw-locking. Male connectors have round contacts diameters of 1,50 mm, 1,00 mm and 0,60 mm.
The different codings provided by this document prevent the mating of accordingly coded male or female connectors to any other similarly sized interfaces covered by other standards and the cross-mating between the different codings provided by this document.
M12 is the dimension of the thread of the screw locking mechanism of these circular connectors.

Key words: Connectors, Circular Connectors, M12.
