Core Specification Parameters of M9 Series Circular Connectors

Key Technical Parameters Overview

Parameter Category Specification Value
Outer Diameter 9mm (pin socket / hole socket)
Standard Core Count 2/3/4/5/6/8 cores
Rated Current 2~5A (depending on core count / wire diameter)
Rated Voltage 30~60V DC
Protection Grade IP67 (mated state, standard version)
Compatible Cable Outer Diameter 3~6mm
Wiring Method Mainly soldering & crimping
Temperature Resistance Range -40℃ ~ +85℃

Technical Note: The rated current of M9 series connectors is positively correlated with wire diameter and negatively correlated with core count; the IP67 protection grade is only valid in the fully mated state, and the protection performance will be reduced when unplugged.
