M8 D-Coded Connectors HARTING M8 D-Coded Connectors provide reliability and data integrity under raw field-level industrial conditions. These IP67 connectors feature a robust metal housing with continuous shielding and supply devices with 100Mbit/s Ethernet. In comparison to the classic M12 connectors, the M8 D-coded series offers 30% reduced dimensions. HARTING M8 D-Coded Connectors are designed to handle the high bandwidths and demanding industrial conditions found in integrated industries. The connectors support the Ethernet protocol standard IEEE 802.3 and are standardized according to PAS IEC 61076-2-114.
