Core Count & Rated Current Correlation of M9 Connectors & Equipment Power Matching

Core Count - Rated Current Correlation Table (DC 30V)

Core Count Rated Current per Core Applicable Scenario
2/3 cores 5A High-current small-channel transmission
4/5 cores 3A Medium-current multi-channel transmission
6/8 cores 2A Low-current multi-channel signal transmission

Equipment Power Matching Method

Matching Formula

Total Power ≤ Rated Voltage × Rated Current per Core × Effective Core Count (reserve 20% margin)
Note: All values are rated under DC 30V.

Application Limitation

Only suitable for signal transmission and low-power power supply scenarios, not applicable for high-power load connection to avoid overcurrent damage.

Technical Note: The rated current of M9 connectors decreases with the increase of core count due to space limitation; the 20% margin is reserved to avoid connector overheating caused by instantaneous current surge in actual use.
