IEC 61076-8-107:2023

Overview

IEC 61076-8-107:2023 is an international standard published by the International Electrotechnical Commission (IEC) that specifies product requirements for power connectors used in electrical and electronic equipment. This standard focuses on free and fixed rectangular connectors with a specific configuration: 2 power contacts rated at 200 A and 1,000 V DC, plus 2 signal contacts rated at 5 A and 50 V DC. The connectors feature plastic housings with locking levers and offer four possible codings for compatibility. These connectors provide individual shielding around each power contact and ensure IP65/IP68 protection when mated and locked, and IPXXB protection when unmated, making them suitable for use in harsh environments where dust and water ingress resistance is critical.

Key features of the IEC 61076-8-107:2023 connectors include high current-carrying capacity, robust mechanical and electrical characteristics, and detailed specifications on dimensions, interface compatibility, technical performance, and test methods.

Key Topics

• Connector Configuration: 2 power poles (200 A, 1,000 V DC) plus 2 signal poles (5 A, 50 V DC) in a rectangular housing.
• Protection Ratings: IP65/IP68 when connectors are mated and locked; IPXXB on plug and receptacle when unmated.
• Housing and Locking: Plastic housing equipped with a locking lever and four distinct coding options to ensure correct mating.
• Shielding: Individual shielding termination around each power contact for superior electromagnetic compatibility (EMC).
• Technical Details: Includes detailed specifications on dimensions, engagement information, termination methods, marking, and current-carrying capacity.
• Performance and Testing: Comprehensive mechanical, electrical, and climatic tests including vibration, shock, temperature cycling, and corrosion resistance to guarantee connector reliability.
• Climatic Classification: Ensures applicability in varied environmental conditions through defined climatic categories.
• Test Schedules: Defined testing protocols, including minimum and full test schedules, to verify compliance with IEC standards.

Applications

IEC 61076-8-107:2023 connectors are designed for demanding electrical and electronic applications that require high-current power distribution combined with low-current control or signal transmission. Typical application scenarios include:

• Industrial Automation: Ensuring reliable power and signal connections in factory automation systems where robust environmental protection is essential.
• Renewable Energy Systems: Suitable for inverters, battery systems, and power electronics in solar and wind energy installations.
• Electric Vehicles (EV) and Charging Infrastructure: Reliable and shielded connectors capable of handling high currents coupled with signal communication for safety and system control.
• Outdoor Equipment: Use in outdoor or harsh industrial environments where dust and water ingress protection (IP65/IP68) is required.
• Telecommunications and Data Centers: Power and signal connectivity in network equipment with stringent electrical performance and EMC requirements.
