Xmost M12 D-coded female front mount PCB socket provides a detachable network cable interface for PROFINET devices and industrial Ethernet equipment. Its 4-pin female connection accepts a compatible M12 D-coded male cable connector, while straight rear contacts connect to the internal circuit board through dip soldering.
The front fastened construction combines panel mounting with direct PCB termination. PG9 and M16 × 1.5 mounting threads accommodate different enclosure designs, with the illustrated PG9 outline defining the socket’s body dimensions and rear contact projection.
Grounded and ungrounded constructions are listed alongside shielded and unshielded options. Specify grounding and shielding separately to match the equipment’s network interface design.
