Siemens 6XV1440-2AH50 Connecting Cable

The 6XV1440-2AH50 serves as a PROFIBUS connecting cable for Siemens automation systems. This cable transmits data between PROFIBUS devices in industrial networks. Its outer diameter measures 8.0 millimeters exactly. The cable comes in standard 50-meter length rolls. You will find this cable weighs approximately 4.5 kilograms per 100 meters. Therefore, installation requires pulling the cable through cable trays or conduits. Two copper conductors carry the RS-485 differential signals.

Physical Construction and Connectors

The cable contains two twisted copper conductors with 1.0 mm² cross-section. A braided copper shield provides excellent electromagnetic interference protection. The outer jacket uses flame-retardant PVC material for safety. You can terminate this cable with standard PROFIBUS connectors. The cable operates reliably in fixed installation applications.

Internal Design and Materials

The 6XV1440-2AH50 uses a special polyethylene insulation for low signal loss. Two colored conductors (red and green) simplify polarity identification during installation. The cable includes a drain wire for easy shield termination. A foil tape wraps around the conductor pair before the braid. The outer PVC jacket resists oil, grease, and many chemicals.

Operational Performance

This PROFIBUS cable transmits data at speeds up to 12 megabits per second. It supports segment lengths up to 1200 meters at lower baud rates. Moreover, the cable maintains signal integrity in electrically noisy environments. You can install this cable in cable trays, conduits, or on cable ladders. The braided shield reduces electromagnetic interference from nearby power cables. The cable withstands bending radii of 5 times the outer diameter. Consequently, you achieve reliable PROFIBUS network cabling for factory installations. Siemens designed this cable for SIMATIC network compatibility. Its robust construction suits industrial floor environments.

In summary, the 6XV1440-2AH50 delivers reliable PROFIBUS connectivity. Use this cable for daisy-chaining PROFIBUS devices. It provides excellent noise immunity for industrial networks. Order this connecting cable for your Siemens PROFIBUS system.
