Siemens 6GK1905-6AA00 – PROFIBUS Fast Connect Bus Cable | SIMATIC NET DP Network
Engineering Background: The Siemens 6GK1905-6AA00 is a purpose-engineered PROFIBUS DP bus cable designed for the SIMATIC NET communication platform. It leverages the Fast Connect termination system, eliminating the need for soldering or crimping during field installation — a critical advantage in time-sensitive commissioning environments and high-density control cabinet builds.
Product Positioning: Targeted at automation engineers and system integrators who require reliable, standards-compliant PROFIBUS DP wiring with minimal installation overhead. This cable is the preferred choice for new installations and retrofit projects across discrete manufacturing, process automation, and motion control architectures.

Engineering Advantages
- Fast Connect termination: Reduces field wiring time by up to 60% vs. conventional screw-terminal connectors
- Dual shielding: Braided + foil construction ensures EMI immunity in high-noise industrial environments
- Violet jacket: Instantly identifiable as PROFIBUS DP per IEC 61158 color convention — simplifies maintenance and troubleshooting
- Consistent impedance: Tight 135–165 Ω tolerance prevents signal reflections at high baud rates (up to 12 Mbit/s)
- Siemens OEM quality: Manufactured to SIMATIC NET specifications — guaranteed interoperability with all Siemens DP devices
System Architecture & Signal Flow
In a PROFIBUS DP network, the 6GK1905-6AA00 connects the DP master (e.g., S7-1500 CM 1542-5 or CP 342-5) to distributed I/O slaves (ET 200SP, ET 200M) and field devices (SINAMICS drives, valve terminals). The cable runs in a linear bus topology with bus termination resistors at both ends. The Fast Connect system mates directly with 6ES7972-0Bxx series connectors — no additional tools required. Maximum segment length is 100 m at 12 Mbit/s, extending to 1200 m at 9.6 kbit/s per EN 50170.

Technical FAQ
Q: Is 6GK1905-6AA00 compatible with PROFIBUS PA?
A: No. This cable is optimized for PROFIBUS DP (RS-485 electrical interface). PROFIBUS PA requires a different cable type (e.g., 6XV1830-0EH10) with 78 Ω impedance.
Q: Can I use this cable with non-Siemens PROFIBUS devices?
A: Yes. The cable complies with EN 50170 / IEC 61158 Type A specifications and is interoperable with any standards-compliant PROFIBUS DP device from any manufacturer.
Q: What connector is recommended for use with this cable?
A: Siemens 6ES7972-0BB52-0XA0 (90° Fast Connect, with PG socket) or 6ES7972-0BA52-0XA0 (straight) are the standard mating connectors.
Q: Is a halogen-free version available?
A: Yes. For halogen-free requirements (e.g., rolling stock, tunnels), specify 6XV1830-0EH10 or consult Konmask for alternative part numbers.
Q: What is the maximum number of nodes per segment?
A: Up to 32 nodes per segment without repeaters; up to 126 nodes total with repeaters per EN 50170.
