IEC 61076-4-107:2001

Overview

IEC 61076-4-107:2001 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies requirements for shielded two-part connectors used in electronic equipment. These connectors are designed with a basic grid of 2.0 mm and include a fixed part suitable for solder and press-in terminations on printed circuit boards (PCBs), as well as a free (movable) part with non-accessible insulation displacement and crimp terminations. This standard forms part of the IEC Quality Assessment System for Electronic Components (IECQ) and ensures the assessed quality of connectors in demanding electronic applications.

The standard provides a detailed framework for the mechanical, electrical, and climatic characteristics of such connectors. It also covers their various models, mounting methods, and termination types to promote compatibility and reliability in global electronic systems.

Applications

IEC 61076-4-107:2001 connectors are essential in various industrial and commercial electronic systems. Typical use cases include:

• Printed Circuit Board Assemblies: Providing robust and reliable connections in complex electronic devices.
• Telecommunications: Supporting high-density and shielded connections within transmission equipment.
• Data and Signal Transmission: Ensuring electrical performance and integrity in environments susceptible to electromagnetic interference (EMI).
• Automotive and Transportation Electronics: Meeting high-reliability and quality requirements for control systems and communication modules.
• Industrial Automation: Facilitating long-life connections within control cabinets, process controllers, and network interfaces.

These connectors are preferred where shielded solutions and multiple termination options are needed to achieve optimal electrical and mechanical performance, while maintaining high standards of quality and reliability.
