What are the applicable scenarios for M16 connectors with different pin counts?

M16 Connector Applications by Pin Count

DC power supply applications such as motors, solenoid valves, and basic industrial power distribution systems.

Mixed power + signal transmission scenarios, including sensor integration with power supply, simple actuator control systems.

Multi-channel signal/bus communication applications like Profinet, DeviceNet, and industrial fieldbus systems.

Complex control system integrations, such as servo drives, PLC module connections, and multi-axis motion control systems.

Pin count selection should match the number of signal/power channels required for the application
Higher pin count connectors may have reduced current rating per pin due to space constraints
Bus communication applications require compliance with relevant industrial protocol standards (e.g., Profinet IEC 61158)
