IEC 61076-2-101:2024描述了M12螺丝锁定圆形连接器，双向可达17？方式，用于频率高达100 MHz的数据传输，以及每个触点高达250 V额定电压和高达4 A额定电流的信号和功率传输。 这些连接器由固定连接器和自由连接器组成，可重新布线或不可重新布线。 公接头有圆形触点，？0.6毫米，？0.76毫米，？0.8毫米还是？1.0 mm根据方式数和编码，所有触点尺寸相同。 不同的编码防止了不同编码的公连接器和母连接器的配合。 这第四版取消并取代了2012年出版的第三版。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更:a)有关尺寸信息（第5条）和特性（第6条）的技术规范已更新，并添加了新的子条款。 b)添加了新型NF（自由连接器）。 c)带玻璃与金属密封件的固定连接器（以前的款式WM、XM、YM、ZM和WF、XF、TF和ZF）不再包含在本文件中:相关定义和要求已被删除。 d)P编码已被消除。 e)附件B（信息性）钢导管螺纹、尺寸已被删除，并添加了与编码相关的新附件B（信息性）电缆出口方向。 f)以前样式AM和BM的尺寸规范已移至新的附录C（规范性）中。

IEC 61076-2-101:2024 describes M12 screw-locking circular connectors with 2-way up to 17？way, for data transmission with frequencies up to 100 MHz and signal and power transmission at up to 250 V rated voltage and up to 4 A rated current per contact.
These connectors consist of fixed and free connectors, either rewirable or non-rewirable.
Male connectors have round contacts,？0,6 mm,？0,76 mm,？0,8 mm or？1,0 mm according to number of ways and coding, all contacts with the same size.
The different codings prevent the mating of differently coded male and female connectors.
This fourth edition cancels and replaces the third edition published in 2012. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Technical specifications regarding dimensional information (Clause 5) and characteristics (Clause 6) have been updated, and new subclauses have been added.
b) New style NF (free connectors) has been added.
c) Fixed connectors with glass to metal seals (former styles WM, XM, YM, ZM and WF, XF, TF and ZF) are no longer covered by this document: relevant definitions and requirements have been removed.
d) The P-coding has been eliminated.
e) Annex B (informative) Steel conduit thread, sizes has been deleted and a new Annex B (informative) Orientation of cable outlet in relation to coding has been added.
f) The dimension specification of former styles AM and BM have been moved into a new Annex C (normative).
