Siemens 6GT2600-4AE00 SIMATIC RF300 MDS D421 ISO 15693 Tool Pill FRAM RFID Transponder

The Siemens 6GT2600-4AE00 is an MDS D421 tool-pill transponder for the RF200 and RF300 read/write systems, a 10 x 4.5 mm epoxy-resin pill built for embedding in metal tool bodies, with a Fujitsu MB89R118 chip for ISO 15693 operation at 13.56 MHz and 2000 bytes of FRAM user memory. It glues into a drilled pocket with zero recommended clearance from surrounding metal and carries an IP67/IPx9K rating.

Selection Notes

At 10 mm diameter with zero mounting clearance, the 6GT2600-4AE00 is built to embed flush in a metal tool holder or cutting tool body, unlike the surface-mounted MDS D460 pill, which needs 10 mm of standoff from metal. It shares the same Fujitsu FRAM chip and 2000-byte memory, so write endurance and capacity are identical between the two; the choice comes down to whether the tag needs to sit on a surface (MDS D460) or inside a metal bore (MDS D421). Without a listed MTBF figure in the source data, plan replacement intervals from the 10-year data retention and the shock/vibration rating instead.
