M12 D-Coded Ethernet Feedthrough Connector
The M12 D-coded Ethernet panel mount coupler establishes a fixed network connection point through industrial equipment walls and control cabinet panels. Its female-to-female configuration allows compatible M12 D-coded male Ethernet connectors to mate from opposite sides of the panel without requiring an additional cable section.
The four-contact D-coded interface is commonly used in industrial Ethernet systems operating at 100 Mbps. Its mechanical coding helps prevent incorrect mating with other M12 connector coding types, while the threaded coupling interface supports secure connections in industrial equipment.
This shielded M12 Ethernet feedthrough connector is suitable for compatible industrial control cabinets, PLC communication systems and factory automation equipment. Final connector compatibility, contact mapping, panel dimensions and shielding continuity should be verified against the approved technical drawing.

Product Features
01. 4-Pin D-Coded Ethernet Interface
The four-contact M12 D-coded interface is designed for compatible industrial Ethernet cable connections. Its coding arrangement supports correct mechanical mating with corresponding M12 D-coded male connectors.
02. Female-to-Female Feedthrough Design
The M12 D-code female to female panel mount coupler provides a detachable Ethernet connection through an equipment wall, enabling compatible cables to connect from both sides without permanent cable splicing.
03. Shielded Industrial Ethernet Connection
The shielded metal housing supports electromagnetic interference protection in industrial networking environments. Shielding performance depends on the complete connector, cable and grounding configuration.
04. Compact Panel Mount Construction
The straight bulkhead design provides an accessible network connection point for industrial control cabinets and equipment enclosures. Final mounting dimensions must be confirmed against the approved mechanical drawing.
Typical Applications
Industrial Control Cabinets
The M12 D-code panel mount Ethernet coupler for industrial control cabinets provides a fixed network interface between external Ethernet cables and internal control equipment. Its feedthrough construction supports organized cabinet wiring, detachable cable connections and convenient maintenance in industrial automation systems.
PLC and Remote I/O Networks
This M12 D-coded connector for PLC communication supports compatible industrial Ethernet connections between PLC controllers, remote I/O modules and industrial network equipment. The four-pin D-coded interface is suitable for appropriately configured 100 Mbps Ethernet communication systems.
Factory Automation Equipment
The 4-pin M12 shielded bulkhead Ethernet adapter can be integrated into compatible industrial machinery, automated production equipment and network enclosures. Its panel-mounted design provides a detachable Ethernet interface for equipment integration, servicing and network extension.
Compatibility and Installation Requirements
M12 D-Coded Connector Compatibility
This M12 D-coded female-to-female coupler is intended for compatible four-contact D-coded male mating connectors. Verify connector coding, contact geometry, gender and mechanical dimensions before integrating the coupler into an industrial Ethernet system.
Industrial Ethernet Protocol Compatibility
The M12 D-coded interface is commonly used in compatible PROFINET, EtherCAT, EtherNet/IP and Modbus TCP networks. Protocol compatibility depends on the complete Ethernet channel, including cable construction, contact assignment, shielding and connected equipment.
Panel Mounting Requirements
Confirm the panel cutout dimensions, mounting thread, panel thickness, sealing components and available installation clearance before installation. The M12 mating interface and the panel mounting thread are separate mechanical features.
Electrical and Shielding Requirements
Verify the connector pin assignment, contact continuity, rated voltage, rated current and shielding continuity according to the approved engineering drawing. A mechanically compatible connector does not automatically guarantee the required Ethernet channel performance.
D-Coded and X-Coded Differences
M12 D-coded Ethernet connectors commonly feature four contacts for 100 Mbps industrial Ethernet applications. M12 X-coded Ethernet connectors commonly feature eight contacts and are used for higher-speed Ethernet applications. These connector coding types are not directly interchangeable.
Environmental Protection
For applications requiring an IP67 M12 D-coded panel mount connector, confirm the actual product protection rating, mating conditions, panel sealing and environmental test requirements. The ingress protection rating must be verified for the supplied connector configuration and installation conditions.
Frequently Asked Questions
What is an M12 D-code panel mount Ethernet coupler?
An M12 D-code panel mount Ethernet coupler is a circular industrial connector used to establish an Ethernet connection through an equipment panel. This configuration features two four-contact female interfaces for compatible M12 D-coded male cable connectors.
What is an M12 D-coded 4-pin connector used for?
An M12 D-coded four-pin connector is commonly used for industrial Ethernet communication in PLC systems, automation equipment, industrial network devices and compatible 100 Mbps Ethernet installations.
Is this coupler compatible with PROFINET?
The M12 D-coded four-contact interface is commonly used in PROFINET applications. Actual compatibility depends on the complete network configuration, cable specifications, contact mapping and applicable communication requirements.
Can this M12 Ethernet coupler be used with other brands?
It may be compatible with M12 D-coded male connectors from other manufacturers when the coding, mating dimensions, contact arrangement and electrical requirements match. Compatibility should be confirmed using the relevant technical drawings.
Does this M12 D-code connector support Gigabit Ethernet?
This four-contact D-coded configuration is intended for compatible 10/100 Mbps industrial Ethernet applications. Standard four-pair 1000BASE-T Gigabit Ethernet connections generally require an eight-contact interface, such as a suitable M12 X-coded connector.
