IEC 61076-2-012:2020规定了带内推的圆形连接器？拉锁机构的尺寸源自M12螺钉，因此与M12螺钉兼容？符合IEC 61076的锁定连接器和配合接口？2？101，IEC 61076？2？109，IEC 61076？2？111和IEC 61076？2？113. 根据本文件的具有内部推拉锁定的母固定连接器可与根据IEC 61076-2-101、IEC 61076-2-109、IEC 61076-2-111或IEC 61076-2-113的具有M12螺钉锁定的相应编码的公自由连接器互配。 本文件涵盖以下两个方面: a)额定电流高达16 A和额定电压高达630 V的电源连接器，通常用于为工业场所中使用的电气设备供电，以及 b)用于频率高达500 MHz的数据和信号传输的连接器。这些连接器包括固定连接器和自由连接器，可重新布线或不可重新布线？可重新布线，带M12内推？如上所述拉动锁定。公接头的圆形触点来自？0.6毫米至？1.5毫米。 本文件涵盖了由其“编码”标识的各种类型的连接器，具有不同的触点布置，不能相互互换。 内推的设计？拉动机构防止公内推的意外配合？用带M12螺钉的母接头拉自由接头？即使对于相同的编码也能锁定。 根据IEC 61076-2-010，本文件中涵盖的带有母触点的一些类型的自由连接器配备了内部和外部推拉锁定，以实现互配，还配备了相应编码的公固定或自由连接器。

IEC 61076-2-012:2020 specifies circular connectors with an inner push？pull locking mechanism of a size derived from and thus being compatible with M12 screw？locking connectors and with mating interfaces according to IEC 61076？2？101, IEC 61076？2？109, IEC 61076？2？111 and IEC 61076？2？113.
A female fixed connector with inner push-pull locking according to this document is intermateable with a correspondingly coded male free connector with M12 screw-locking according to IEC 61076-2-101, IEC 61076-2-109, IEC 61076-2-111 or IEC 61076-2-113.
This document covers both:
a) power connectors with current ratings up to 16 A and voltage ratings up to 630 V, typically used for power supply of electrical equipment used in industrial premises, and
b) connectors for data and signal transmission with frequencies up to 500 MHz.
These connectors consist of both fixed and free connectors, either rewirable or non？rewirable, with M12 inner push？pull locking as explained above. Male connectors have round contacts from？0,6 mm up to？1,5 mm.
This document covers various types of connectors identified by their "codings" with different contact arrangement, not mutually interchangeable.
The design of the inner push？pull mechanism prevents the unintended mating of the male inner push？pull free connector with the female connector with M12 screw？locking even for identical coding.
Some styles of free connectors with female contacts covered in this document are equipped with both inner and outer push-pull locking for intermateability also with correspondingly coded male fixed or free connectors according to IEC 61076-2-010.
