Product Overview
Banner STP-M12D-406 is a double-ended industrial Ethernet cordset connecting a 4-pin M12 D-code male connector to an 8-pin RJ45 male connector over 1.83 meters (6 feet) of shielded Cat5e cable. The teal PUR jacket carries UL CM 75°C and E189501 listings confirmed on the label. Nickel-plated brass coupling nuts on the M12 end provide secure engagement with panel-mount M12 D-code receptacles. Built for industrial Ethernet protocols including EtherNet/IP, PROFINET, EtherCAT, and Modbus TCP.

Applications
- Connecting M12 D-code Ethernet field devices (sensors, drives, I/O blocks) to RJ45-based managed or unmanaged switches
- EtherNet/IP and PROFINET network drops in manufacturing and process control panels
- Washdown or wet environment installations requiring IP67 connector sealing at the field device end
- Replacing damaged or missing cordsets on existing Banner, Turck, Balluff, or other M12 D-code Ethernet devices
Frequently Asked Questions
Will this cable work with my M12 A-code or M12 B-code device?
No. The STP-M12D-406 uses M12 D-code keying exclusively. D-code connectors are physically and electrically different from A-code (used for sensors and power) and B-code (used for PROFIBUS). Verify your device's M12 connector coding before ordering.
Does this cordset include the original Banner packaging or documentation?
Not included. The unit is unused but was acquired without original packaging or paperwork.
Is this cable rated for outdoor or washdown use?
The M12 connector end is rated IP67, providing protection against dust ingress and temporary water immersion. The RJ45 end uses a standard shielded connector without an IP rating - confirm the RJ45 termination point is appropriately protected for your installation environment.
What Ethernet protocols does this cordset support?
The STP-M12D-406 is a passive shielded Cat5e cable assembly. It supports any 100 Mbps industrial Ethernet protocol using M12 D-code and RJ45 terminations, including EtherNet/IP, PROFINET, EtherCAT, and Modbus TCP. It does not include active electronics.
Is 1.83 meters long enough for my application?
1.83 m (6 ft) covers short panel-to-device or switch-to-field runs. If you need a longer run, Banner offers other STP-M12D variants in different lengths under separate model numbers.
Six feet of shielded teal cable sounds modest until you are standing between a managed switch and an Ethernet I/O block with nothing else on hand. This one is unused, connectors are clean, and it is ready to close that gap today.
