Siemens 6ES5731-1BF00 Plug-in Cable

Physical Dimensions and Mechanical Construction

The Siemens 6ES5731-1BF00 connects SIMATIC S5 modules for reliable system communication. This cable measures 2000mm in total length and 8mm in outside diameter. You can bend this cable to a minimum radius of 40mm for flexible routing inside cabinets. The cable weighs 0.18 kilograms , making it easy to handle during installation.

Internal Architecture and Component Details

The Siemens 6ES5731-1BF00 contains 20 individual conductors arranged in a twisted-pair configuration. Each conductor uses stranded copper wire with 0.14mm² cross-section for flexibility. A braided copper shield covers all conductors to block electromagnetic interference. Additionally, the cable includes two molded connector hoods at both ends for strain relief.

Connector Interfaces and Pin Configuration

This plug-in cable provides two 20-pin IDC connectors for direct module attachment. Each connector has polarization keys to prevent incorrect insertion into SIMATIC S5 units. The connectors feature screw-locking mechanisms for vibration-resistant connections. Furthermore, the cable offers pin-to-pin straight wiring for simple system integration.

Electrical Specifications and Signal Integrity

The Siemens 6ES5731-1BF00 maintains 100 ohm characteristic impedance for signal matching. This cable has a capacitance of 60 pF per meter for predictable signal behavior. The twisted-pair construction reduces crosstalk between adjacent signal lines significantly. Furthermore, the braided shield provides >80 dB attenuation of external electromagnetic noise.

Connector Durability and Construction

Both connectors on the Siemens 6ES5731-1BF00 feature molded PVC housings for impact resistance. Each connector uses gold-plated contacts to prevent corrosion over time. The connectors withstand 500 mating cycles without performance degradation. Additionally, the cable includes color-coded strain relief boots for easy identification.

Compatibility and System Integration

This plug-in cable works exclusively with Siemens SIMATIC S5 programmable controllers. You can use this cable to connect CPU modules to I/O modules on the same rack. The cable also links remote I/O stations for distributed system configurations. Furthermore, the unit supports signal transmission up to 5 meters without active repeaters.

Installation and Routing Guidelines

You should avoid routing the Siemens 6ES5731-1BF00 near power cables or motor drives. Maintain at least 100mm separation from high-voltage conductors for noise immunity. Use the included cable ties to secure the cable along designated wireways. Do not exceed the 40mm bend radius to prevent conductor damage over time.

Environmental and Safety Compliance

You can operate this plug-in cable from 0°C to 60°C ambient temperature without issues. Storage temperature ranges from -20°C to 70°C for long-term preservation. The cable uses VW-1 rated insulation for flame retardancy in industrial settings. This product meets UL 2464 and CE standards for communication cables.
