Overview
IEC 61076-4-101:2001 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies requirements for printed board connectors with assessed quality. This standard covers detailed specifications for two-part connector modules designed on a 2.0 mm basic grid, compatible with printed boards and backplanes as defined by IEC 60917. It is referenced within the IEC Quality Assessment System for Electronic Components (IECQ), ensuring reliability and consistency in connector performance.
This standard includes the corrigendum from November 2003, providing the most up-to-date requirements for connector design, application, mechanical and electrical characteristics, quality assessment, and testing.
Key Topics
- Connector Modules: Defines two-part modules utilizing a 2.0 mm grid suitable for modular equipment.
- Quality Assessment: Sets procedures for qualification approval, lot-by-lot testing, and ongoing conformity assessment in line with IECQ requirements.
- Mechanical and Electrical Characteristics:
- Contact and termination styles
- Engagement sequence and mechanical coding
- Shielding and grounding practices
- Dimensions and tolerances for reliable interconnection
- Testing and Conformance: Includes detailed test schedules for mechanical endurance, electrical integrity, environmental resistance, and flammability.
- Marking and Ordering: Provides guidance on standard type designation, proper product marking, and ordering information.
Applications
Adhering to IEC 61076-4-101:2001 assures manufacturers, OEMs, and system integrators of reliable, interoperable electronic connectors in the following applications:
- Industrial Control Systems: Ensures robust and reliable connections between PLCs, modules, and rack-mounted equipment.
- Telecommunications and Networking: Supports backplane and board-to-board interconnections where dense, modular designs are critical.
- Data Centers and Servers: Provides high-density, quality-assessed connectors for server and storage backplanes.
- Instrumentation and Medical Devices: Enables assured quality and repeatable performance in mission-critical systems.
- Modular Electronics: Facilitates systems using the IEC 60917 modular equipment practice, ensuring standardization across assemblies.
