3-Core (Power Only):
• For pure power supply scenarios with no signal transmission
4-Core (Power + Simple Signal):
• Suitable for applications with basic power + simple signal transmission
5-Core (Multi-IO / Multi-Signal):
• Ideal for multi-channel IO or multi-signal transmission scenarios
6-Core (Complex Control):
• For applications with more signal channels and complex control logic
Technical Note: Select 7/8" connector core count strictly according to actual power/signal demand - avoid over-specification (wasting cost) or under-specification (insufficient channels) to ensure optimal cost-performance and functionality.
