The Siemens SIMATIC RF260R (6GT2821-6BC32) is a compact HF RFID reader with an IO-Link V1.1 interface, designed for identification tasks in intralogistics and production environments. With an integrated antenna delivering up to 135 mm read range and full IP67 protection, it is suited for direct mounting on assembly lines, conveyor systems, and workpiece carrier handling stations. The IO-Link interface enables plug-and-play connection to IO-Link master modules, with configuration, diagnostics, and maintenance handled through TIA Portal.

What RFID Standards and Transponders Does the RF260R Support?

The RF260R operates at 13.56 MHz and supports transponders conforming to ISO 15693 and ISO 18000-3. It is compatible with Siemens SIMATIC RF200 transponders including the MDS D100, D124, D126, D139, D160, D165, D200, D324, D339, D421, D424, D425, D426, D428, D460, D524, and D528 series. The maximum RF data transfer rate is 26.5 kbit/s, with a read access time of approximately 2.4 ms per byte and write access time of approximately 3.3 ms per byte. The RF260R is not multi-tag capable — it reads one transponder at a time.

How Does the IO-Link Interface Work?

IO-Link V1.1 provides point-to-point communication between the reader and an IO-Link master at 230 kbit/s (COM3), with 32 bytes of input and output process data. The reader connects via a standard M12 4-pin connector, with a maximum cable length of 20 m between the reader and the IO-Link master. The master then communicates upstream via PROFINET or PROFIBUS to the PLC. Power is supplied at 24 V DC (20.4–28.8 V range) through the IO-Link connection, with typical current consumption of 50 mA. All engineering, commissioning, and diagnostics are integrated into TIA Portal for streamlined workflow.

What Are the Mechanical and Environmental Specifications?

The RF260R measures 75 × 75 × 41 mm and weighs 0.200 kg, with a PA 6.6 polyamide housing in anthracite color. It mounts using two M5 screws (max. tightening torque 1.5 N·m) and can be installed directly on metal surfaces with no minimum clearance required. The IP67 rating ensures full protection against dust ingress and temporary immersion. Operating temperature range is −20 °C to +70 °C, with storage and transport tolerance from −25 °C to +80 °C. Shock resistance is rated at 500 m/s² (EN 60721-3-7 Class 7 M2) and vibration resistance at 200 m/s². The MTBF is 480 years.

Frequently Asked Questions

How does the RF260R compare to the RF250R?

The RF260R (75 × 75 × 41 mm, 0.200 kg) features an integrated antenna with up to 135 mm read range and IP67 protection, making it a self-contained solution for applications where the reader and antenna are in one housing. The RF250R (50 × 50 × 30 mm, 0.014 kg) is a compact reader without an integrated antenna — it requires connection to an external antenna (ANT 1, ANT 3, ANT 3NO, ANT 8, ANT 12, ANT 18, or ANT 30), offering flexibility in antenna placement but with IP65 rating.

Can the RF260R IO-Link variant be used with third-party IO-Link masters?

Yes. The RF260R with IO-Link V1.1 conforms to the IO-Link standard and can be connected to any certified IO-Link master. However, full TIA Portal integration for engineering and diagnostics requires a Siemens IO-Link master (e.g., SIMATIC ET 200SP or ET 200pro).

What is the recommended cable between the RF260R and the IO-Link master?

A standard M12 4-pin IO-Link cable, maximum 20 m in length. Siemens recommends shielded cables for industrial environments with high electromagnetic interference.
