3/4/5 Core:
• 3-core: Basic power supply (S/K coding)
• 4-core: General signal/sensor connection (A coding)
• 5-core: Field bus communication (B coding)
6/8/12/17 Core:
• 6-core: Multi-channel signal transmission
• 8-core: Gigabit Ethernet (X coding)
• 12/17-core: High-density signal/power integration
Typical Matches:
• A coding: 4/5 core (signal transmission)
• B coding: 5 core (DeviceNet/CANopen)
• D coding: 4 core (100M Ethernet)
• X coding: 8 core (1000M Ethernet)
• S/K coding: 3 core (power transmission)
Selection Principle:
• Confirm core count based on transmission channel needs
• Match with corresponding coding to ensure compatibility
Technical Tip: The core count of M12 connectors is closely linked to coding type - select the appropriate core count according to the number of transmission channels, and match the corresponding coding to ensure physical compatibility and transmission performance. For example, choose 8-core X coding for gigabit Ethernet applications to meet high-speed transmission requirements.
