Adapted to small core count and low power scenarios, with the smallest outer diameter, suitable for miniaturized sensor and low-power actuator connection.
Niche intermediate specification, filling the size gap between M8 and M12, with more flexible core count/current adaptability, focusing on customized signal and low-power power supply for miniaturized equipment (no universal industrial bus protocol support).
Adapted to multi-core count and higher power/industrial bus scenarios (such as Profinet/EtherNet/IP), the most widely used industrial standard specification.
Technical Note: M9 series is a non-universal customized specification, which is mainly used in special miniaturized equipment that cannot be covered by M8/M12, and does not support mainstream industrial bus protocols due to size and structural limitations.
