标准范围

IEC 61076-3-122:2021涵盖8路、屏蔽、自由和固定矩形连接器，用于频率高达500 MHz的I/O和数据传输。它旨在规定该系列连接器的通用尺寸、机械、电气和环境特性以及测试。符合本文件的连接器提供IP20的防护等级；然而，它们特别适用于具有高振动水平的工业环境。本文件中定义了两类连接器，用“A类”和“B类”表示，它们通过一些电气和机械特性来区分，以满足一些工业应用的特定要求。A级符合本文件第1版规定的要求。根据ISO/IEC 11801中定义的组件类别Cat 5和Cat 6A，具有A和B两个类别、I和II两种编码类型以及两组传输要求-如图1所示，本文档规定了2 × 2 × 2=8个变体。本文件涵盖的所有连接器的载流能力均超过ISO/IEC 11801 1中定义的60°C环境温度下每引脚0.75 A的最低要求。这第二版取消并取代了2017年出版的第一版。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)标题已修改。b)引入“A类”和“B类”连接器的两组要求，其中A类与上一版本中定义的要求相匹配。c)除了先前版本提供的高达100 MHz的性能要求之外，还定义了高达500 MHz的频率的新性能要求。d)重组以反映连接器类型I和类型II之间的共性和差异。e)修订图纸以澄清某些尺寸。e)降额图已被校正，使其与气候类别中的上限温度一致，目标应用的性能没有降低。

IEC 61076-3-122:2021 covers 8-way, shielded, free and fixed rectangular connectors for I/O and data transmission with frequencies up to 500 MHz. It is intended to specify the common dimensions, mechanical, electrical and environmental characteristics and tests for this family of connectors.
Connectors complying with this document provide an ingress protection level of IP20; however, they are particularly suited for industrial environments with a high level of vibration.
There are two classes of connectors defined in this document, indicated by "class A" and "class B" which are distinguished by some electrical and mechanical characteristics to meet the particular sets of requirements of some industrial applications.
Class A meets the requirements defined in Ed.1 of this document.
With the two classes A and B, the two codings Type I and II, and the two sets of transmission requirements according to the component categories Cat 5 and Cat 6A as defined in ISO/IEC 11801-1, this document specifies 2 × 2 × 2 = 8 variants.
All connectors covered by this document feature a current-carrying capacity beyond the minimum requirement of 0,75 A per pin for an ambient temperature of 60° C as defined in ISO/IEC 11801 1.
This second edition cancels and replaces the first edition published in 2017. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Title modified.
b) Introduction of two sets of requirements for connectors of "class A" and "class B" where class A matches the requirements defined in the previous edition.
c) Definition of new performance requirements for frequencies up to 500 MHz in addition to the performance requirements up to 100 MHz provided with the previous edition.
d) Re-structuring to reflect the commonalities of and differences between connector Type I and Type II.
e) Revision of drawings to clarify some dimensions.
e) The derating diagram has been corrected to align it with the upper limiting temperature in the climatic category, with no reduction of performance for the target applications.
