Compatibility of 8-core A-coded & 8-core D-coded M12 Connectors

Core Conclusion

  • Cannot Be Replaced With Each Other : Although both A-coded and D-coded have 8-core specifications, the two types of connectors have completely different design purposes and pin definitions, and are not interchangeable in any case.

Core Functional Differences & Application Orientation

8-core A-coded

Focus on multi-channel sensor signal transmission, the pin allocation is mainly based on power supply + multi-channel signal transmission, suitable for the connection of industrial multi-signal acquisition equipment.

8-core D-coded

Specialized for industrial Ethernet transmission, the pin definition strictly complies with the Ethernet differential signal transmission standard, dedicated to high-speed stable network data communication transmission.

Technical Note: Blind replacement of the two types of connectors will lead to serious communication failure, such as data packet loss, unstable transmission and complete inability to communicate, and even cause hidden danger of circuit mismatch in individual cases.
