M12 D-coded male front mount PCB connector provides a detachable network cable interface for industrial Ethernet devices and PROFINET equipment. Its 4-pin male interface mates with a compatible M12 D-coded female cable connector, while straight rear contacts connect to the internal PCB through dip soldering.
The front fastened construction integrates the M12 Ethernet connection into the equipment panel. PG9 and M16 × 1.5 mounting options accommodate different enclosure designs, with the illustrated PG9 outline defining the connector’s panel-to-board dimensions.
Grounding and shielding should be specified according to the equipment design. Select the connector as part of the complete Ethernet assembly, including the mating cable, PCB routing and shielding arrangement.
Key Features
