Siemens Simatic RF, MV plug-in cable, pre-assembled, 20m Part number 6GT2891-4FN20

Product Overview

The Siemens 6GT2891-4FN20 is a plug-in (or extension) communication cable from the SIMATIC RF / Indus.Sector family. It is used to connect an RFID reader or communication module (e.g. ASM 456, RF160C, RF170C, RF18XC) to an external interface or reader, enabling reliable and flexible wired connection for industrial RFID / automation systems. With a 20 m length and robust PUR-sheathed construction, it is suitable for demanding industrial environments, allowing extended reach between readers and modules.

Key Features

• Pre-assembled 6-core communication cable for SIMATIC RF / Indus.Sector systems
• M12 8-pin connectors (male one end, female the other) — straight orientation
• Length: 20 m — extends reach between RFID readers/modules and controllers
• Cable sheath: PUR — resistant against oil, grease, mechanical stress and industrial wear
• Shield: braided tin-plated copper — provides EMI protection and reliable signal integrity
• Operating ambient temperature: –30 °C to +80 °C — suitable for harsh industrial conditions
• Mechanical robustness: designed for multiple bending cycles and flexible routing (minimum bend radii specified)
• Voltage rating: up to 300 V (suitable for typical RS-422 / module communication voltages)
• UL/ETL and EAC approvals — compliant for international industrial installations

Applications

The 6GT2891-4FN20 cable is used wherever a robust, long-reach connection is required between RFID readers or communication modules and controllers or other system modules in industrial automation setups. Typical applications include conveyor-based tracking, logistic systems, container tracking, warehouse automation, machine-mounted RFID readers connected to control cabinets, or any installation requiring a rugged, shielded, flexible communication cable over distances up to 20 m. Its durability and environmental resistance make it suitable for harsh, oil-, dust-, or moisture-exposed factory-floor environments.
