6FX2003-0DM67 | Siemens MOTION-CONNECT RJ45 Signal Connector — DRIVE-CLiQ / IP67 Metal Version

Rugged Metal RJ45 Connector for DRIVE-CLiQ Interface Connections

The 6FX2003-0DM67 is Siemens' metal-bodied RJ45 signal connector for the DRIVE-CLiQ interface — the digital communication and feedback bus used throughout the SINAMICS drive system to connect motors, encoders, and drive components. DRIVE-CLiQ carries both power and high-speed serial communication over a single RJ45-format cable connection, making the connector's mechanical and environmental robustness directly relevant to system reliability.

The 6FX2003-0DM67 metal version replaces the earlier plastic-bodied 6FX2003-0DC67 connector — Siemens upgraded the construction material specifically to achieve the IP67 protection rating and the mechanical durability needed in demanding machine tool and industrial automation installation environments.

Key Specifications

DRIVE-CLiQ — The Interface This Connector Serves

DRIVE-CLiQ (Drive Component Link with IQ) is Siemens' proprietary digital interface for the SINAMICS drive system — connecting drive components in a structured digital communication topology:

Integrated motor encoder communication: SINAMICS-compatible motors with an integrated DRIVE-CLiQ interface in the encoder communicate position, speed, and motor identification data directly to the SINAMICS drive over the DRIVE-CLiQ link — eliminating the separate resolver or analogue encoder cable interfaces used in older drive generations.

Plug-and-identify capability: DRIVE-CLiQ-equipped components carry digital identification data readable by the SINAMICS drive at connection — supporting automatic component recognition and configuration verification, reducing commissioning errors from incorrect cable or motor type selection.

Daisy-chain and star topologies: DRIVE-CLiQ supports both daisy-chain (sequential module-to-module) and star (hub) wiring topologies depending on the specific SINAMICS hardware configuration — the RJ45 connector format is common across both topology types.

Applications

SINAMICS S120 motor connections: DRIVE-CLiQ interface connections between SINAMICS S120 motor modules and SIMOTICS servo motors with integrated DRIVE-CLiQ encoders — the standard connector at the motor-side DRIVE-CLiQ port.

CNC machine tool servo axes: SINUMERIK CNC machine tools using SINAMICS S120 drive systems with DRIVE-CLiQ motor encoder feedback — the IP67 rated connector withstands the coolant exposure typical at the motor connection point.

Industrial robot joint drives: SINAMICS-based robot servo drive systems where DRIVE-CLiQ connections at each joint motor require robust, sealed connector performance in the robot's operating environment.

Replacement and field repair: Replacing damaged DRIVE-CLiQ connectors during field maintenance — particularly where the original plastic 6FX2003-0DC67 connector has failed, the metal 6FX2003-0DM67 provides a direct functional upgrade in the same connector position.

FAQ

Q1: Is 6FX2003-0DM67 a drop-in replacement for the older 6FX2003-0DC67 plastic connector?

Yes — the 6FX2003-0DM67 metal version is the direct successor to the 6FX2003-0DC67, sharing the same RJ45 connector interface and DRIVE-CLiQ pin assignment. The metal version can replace the plastic version in the same application, providing improved mechanical durability and IP67 environmental sealing as a functional upgrade.

Q2: Does the IP67 rating apply to the connector alone, or does it require a specific mating cable construction?

The IP67 rating of the 6FX2003-0DM67 connector itself describes the connector's sealing performance when correctly mated and engaged. Achieving the full IP67 protection in the assembled cable system also requires using a DRIVE-CLiQ cable rated to the same protection class and ensuring the connector is fully seated and locked. Confirm the complete cable assembly's IP rating from Siemens' DRIVE-CLiQ cable documentation, as the cable jacket and strain relief also contribute to the overall system protection level.

Q3: What signals does the DRIVE-CLiQ interface carry through this connector?

DRIVE-CLiQ carries a combination of low-voltage DC power (supplying the connected component's electronics) and high-speed serial digital communication (encoder position data, component identification, diagnostic data, and firmware information) over the same RJ45-format cable connection. The 6FX2003-0DM67 connector's pin configuration accommodates this combined power-and-data interface within the standard 8-position RJ45 format.

Q4: Can 6FX2003-0DM67 be used with SINAMICS drive generations other than S120?

DRIVE-CLiQ is used across multiple SINAMICS drive platforms beyond S120, including certain S110 and other current-generation Siemens drive systems that adopted the DRIVE-CLiQ interface standard. Confirm from the specific drive system's hardware documentation whether the DRIVE-CLiQ interface and connector specification match — while the RJ45 physical connector format is consistent across DRIVE-CLiQ-equipped platforms, always verify compatibility against the specific drive and motor combination in the installation.
