6XV1871-5TH20 2m IE Connecting Cable M12/RJ45

Introduction to the Siemens 6XV1871-5TH20

When network reliability matters in harsh industrial environments, the 6XV1871-5TH20 from Siemens provides a robust connection. This flexible plug-in cable is preassembled with one 4-pole M12 connector (D-coded) and one IE FC RJ45 plug 145. It is designed for connecting Industrial Ethernet stations such as SIMATIC ET200pro, SCALANCE X208PRO, and SIMOTION. With a length of 2.0 meters, this cable suits short-distance, links.

Key Features and Technical Specifications

The 6XV1871-5TH20 is engineered for demanding applications. Its key parameters include:

• Wire length: 2 m

• Number of electrical cores: 4
• Shield design: Overlapped aluminum-clad foil, sheathed in a braided screen of tin-plated copper wires
• Core diameter (AWG22 insulated conductor): 0.75 mm
• Outer diameter of cable sheath: 6.5 mm
• Bending radius (single bend): 32.5 mm minimum
• Bending cycles: 3,000,000 (drag chain suitable)
• Operating voltage (RMS): 80 V
• NVP value: 66%
• Impedance at 1 MHz to 100 MHz: 100 Ω
• Attenuation at 10 MHz: 0.063 dB/m max
• Attenuation at 100 MHz: 0.213 dB/m max
• Ambient temperature during operation: -25 to +75 °C
• Flame resistant according to UL 1685 (CSA FT 4)
• PoE and PoE+ capable: Yes
• Silicon-free: Yes

This cable supports Power over Ethernet (PoE and PoE+), making it versatile for powered devices. Its robust shield ensures signal integrity in electrically noisy environments.

Applications and Use Cases

For example, it links ET200pro I/O stations to SCALANCE switches, ensuring reliable data transfer. In drag chain applications, the cable withstands millions of bending cycles, reducing downtime. Its flame resistance and chemical resistance make it suitable for machine tools and automotive plants.

Installation and Setup

Because the cable is preassembled, installation is straightforward. Simply connect the M12 connector to the device and the RJ45 plug to the switch. Ensure the cable is routed with a bending radius of at least 32.5 mm for single bends and 49 mm for multiple bends. For continuous bending, maintain a radius of 100 mm. Avoid exceeding the maximum tensile load of 150 N.

Maintenance and Reliability

Regular inspection of the cable and connectors is recommended to ensure secure connections. The cable's drag chain suitability (3 million cycles) and flame resistance contribute to long service life. Its UV resistance and conditional resistance to oil, grease, and water enhance reliability in harsh conditions. Periodic checks for wear on the sheath can prevent unexpected failures.

Compatibility and Integration

The 6XV1871-5TH20 is designed for Industrial Ethernet networks, specifically PROFINET. It works with Siemens devices such as SIMATIC ET200pro, SCALANCE X208PRO, and SIMOTION. The M12 D-coded connector ensures a secure, IP-rated connection, while the RJ45 plug allows standard switch connectivity. This cable is Cat5e compliant, supporting 100 Mbps Ethernet.

Troubleshooting and Common Issues

If network issues occur, first verify that the cable is not bent beyond its minimum radius. Check for physical damage to the sheath or connectors. Ensure the M12 connector is fully tightened to avoid loose connections. If using PoE, confirm the cable is not exceeding its voltage rating of 80 V RMS. For persistent issues, consult the Siemens documentation or contact AutoDCSTech.

Buyer's Guide: Evaluating the 6XV1871-5TH20

When selecting an Industrial Ethernet cable, consider the following factors:

• Length: 2 meters is suitable for short runs between devices.
• Connector types: M12 D-coded and RJ45 provide flexibility for industrial and standard connections.
• Environmental resistance: Flame, UV, and chemical resistance ensure durability.
• PoE support: Enables power delivery over the same cable.

This cable meets these criteria, making it a reliable choice for PROFINET networks.
