Product Dimensions：

The 6GK1905-6AA00 connector is a core component of the Siemens FastConnect cabling system, which streamlines on-site assembly of Industrial Ethernet cables without requiring specialized soldering or complex wire stripping. It features a durable, industrial-grade metal enclosure that provides superior mechanical strength and full 360-degree shielding against electromagnetic interference. The plug uses insulation displacement connection (IDC) contacts, allowing users to terminate 4-core FastConnect twisted-pair cables quickly and securely. Its straight 180-degree design is optimized for direct insertion into Industrial Ethernet switches, SIMATIC PLCs, human-machine interfaces, and other automation devices equipped with standard RJ45 sockets.

Product Advantages

A key advantage of the Siemens 6GK1905-6AA00 plug is its FastConnect technology, which significantly minimizes installation time and eliminates termination errors during field assembly.

The robust metal housing provides high mechanical durability, strain relief, and effective shielding against severe electrical noise commonly found near industrial drives and high-voltage lines.

The insulation displacement contacts create long-lasting, vibration-resistant connections that remain reliable even in high-vibration manufacturing environments.

Its standardized RJ45 form factor ensures high compatibility with a broad spectrum of Siemens automation equipment as well as third-party industrial Ethernet devices.

Important Considerations and Precautions

When installing the 6GK1905-6AA00 connector, always use the dedicated Siemens IE FC Stripping Tool to ensure correct conductor lengths and avoid damaging the internal copper wires or outer shield.

This connector is rated IP20, meaning it is intended for installation inside control cabinets, junction boxes, or protected enclosures, and should not be exposed directly to liquids or heavy dust without an outer protective enclosure.

Ensure the outer cable jacket and shield are positioned properly within the connector body before locking the housing to maintain 360-degree shielding continuity and proper strain relief.

Do not exceed the specified bending radius of the attached Industrial Ethernet cable near the 180-degree strain relief outlet to prevent internal wire fatigue or signal attenuation.

Confirm that the network application operates within 10/100 Mbit/s limits, as this 4-core connector is designed for Fast Ethernet and not Gigabit Ethernet infrastructure.

Product Applications

The 6GK1905-6AA00 connector is widely deployed across industrial automation networks requiring dependable Fast Ethernet connectivity.

SIMATIC PLC Networking: Connecting Industrial Ethernet cables to S7-300, S7-400, S7-1200, and S7-1500 controller communication modules.
Industrial Switch Infrastructure: Terminating field cables at SCALANCE X industrial Ethernet switches and media converters inside control panels.
HMI and Visualisation Panels: Linking operator panels, industrial PCs, and touchscreens to the plant-wide control network.
Fieldbus and PROFINET Trunking: Establishing physical layer connections for PROFINET IO networks between controllers, distributed I/O islands, and field drives.
Factory and Process Automation: Wiring communication lines in automotive manufacturing, water treatment plants, packaging machinery, and material handling systems.
