Connector Certification Standards

The core certification standards for connectors in 2025 mainly cover industrial circular connectors and power connectors, covering key parameters such as M12 threaded locking, high current transmission, and IP protection levels.

1. Circular Connector Standards
IEC 61076-2-111:2025: Applicable to 4 to 6-core circular connectors with M12 threaded locking, supporting rated currents of 8/12/16A, voltage divided into 50V AC/60V DC or 630V levels, and the code determines the voltage level, mainly used for power supply in industrial settings.
IEC 61076-2:2025: Circular connector specification, unifying product specifications and quality assessment requirements, covering technical parameters and testing methods.

2. Power Connector Standards
IEC 61076-8-111:2025: Specifies 3-core 20A rated current, plastic housing quick lock, IP65/IP67 protection for rectangular connectors, suitable for power connections of electronic and electrical equipment.
IEC 61076-8-112:2025: For rectangular connectors with 2 cores, 50A high current, the same quick lock housing and IP65/IP67 protection, meeting higher power transmission requirements.

3. Data Transmission Connector Standards
BS EN IEC 63171:2025: Applicable to balanced single-pair data transmission with current-carrying capability, shielding/non-shielding connectors, referring to multiple standards such as IEC 60068-1:2013 environmental testing and IEC 60512-1 electrical testing, covering general requirements and testing methods.
