Siemens MDS D421 RFID Transponder for Tool Coding DIN 69873, 13.56 MHz, FRAM 128 bytes, IP68, PEEK, 6GT2600-4AE00

The Siemens MDS D421 transponder stands out as a dedicated RFID data carrier for tool identification, specifically engineered to meet DIN 69873 for tool coding. Unlike general-purpose tags, it is designed to be embedded directly into tool holders, enabling reliable and contactless identification in automated manufacturing environments.

Highlights

• Passive RFID transponder operating at 13.56 MHz (HF), compatible with SIMATIC RF200/RF300 systems.
• FRAM memory with 128 bytes capacity, supporting unlimited read/write cycles and 10-year data retention.
• Robust PEEK housing with IP68 protection, suitable for harsh industrial conditions.
• Designed for tool coding according to DIN 69873, with mounting as an embeddable key.

In daily use

In CNC machining centers and flexible manufacturing systems, the MDS D421 is inserted into tool holders to store tool-specific data such as tool ID, offset values, and life status. Its short read range of up to 20 mm ensures precise identification at the tool magazine or spindle. The FRAM technology allows frequent updates without wear, and the PEEK material withstands coolants, oils, and temperature fluctuations from -25 to +85 °C.
