BS EN IEC 61076-3-122:2021

What is IEC 61076‑3‑122 about?  

BS EN IEC 61076‑3‑122 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. 

Note 1: In terms of the MICE system as defined in ISO/IEC 11801-1, the connector matches the requirements of the M3I1C3E3 levels. 

Note 2: Class A meets the requirements defined in Ed.1 of BS EN IEC 61076‑3‑122. 

Note 3: With the two classes A and B, the two coding 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, BS EN IEC 61076‑3‑122 specifies 2 × 2 × 2 = 8 variants.  

Who is BS EN IEC 61076‑3‑122 for? 

BS EN IEC 61076‑3‑122 on 8-way, shielded, free and fixed connectors are useful for: 

• Manufacturers of electrical connectors 
• Technician and electrician 
• Electrical engineers 
• Quality control personnel 

Why should you use BS EN IEC 61076‑3‑122?  

Connectors carry power to electrical devices, transmit data or electrical signals. Circular connectors need to meet certain quality standards as they have to withstand rugged conditions in their operational life.  

BS EN IEC 61076‑3‑122 covers detailed specifications for 8-way, shielded, free and fixed connectors for I/O and data transmission with frequencies up to 500 MHz and current carrying capacity in industrial environments. 

BS EN IEC 61076‑3‑122 provides you with guidance on 8-way, shielded, free and fixed connectors mating information and their characteristics and dimensions that will aid in the production phase. BS EN IEC 61076‑3‑122 also provides you guidance on test methods to evaluate the connectors and guides you through the sequence as well to ensure quality assurance on your products. 

In conclusion, the guidelines of BS EN IEC 61076‑3‑122 enable you to produce high-quality durable connectors with long operational life. 

What’s changed since the last update?  

BS EN IEC 61076‑3‑122:2021 supersedes BS EN 61076‑3‑122:2017. BS EN IEC 61076‑3‑122:2021 includes some technical changes concerning BS EN 61076‑3‑122:2017. These include: 

• Title modified 
• 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. 
• 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.  
• Re-structuring to reflect the commonalities of and differences between connector Type I and Type II. 
• Revision of drawings to clarify some dimensions. 
• 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.
