Siemens 6GT2600-3AA10 SIMATIC RF300 MDS D339 ISO 15693 220C Heat-Resistant RFID Transponder

The Siemens 6GT2600-3AA10 is an MDS D339 transponder for the RF200, RF300 and MOBY D read/write systems, an 85 x 15 mm PPS disc with an Infineon My-D SRF 55V10P chip built for ISO 15693 operation at 13.56 MHz and 992 bytes of EEPROM user memory. It withstands continuous operation up to 100 C and short excursions to 220 C outside the read/write zone, with IP68/IPx9K sealing and an IECEx hazardous-location marking.

Selection Notes

The 220 C outside-zone rating is the highest in the MDS D3xx button family, well above the 180 C ceiling of the MDS D124, and the IECEx marking (Ex nA II T2, Ex tD A22 IP68 T210) is scoped for Zone 2/22 rather than the Zone 0/20 marking on that smaller unit, so confirm the zone classification matches the installation before ordering. The 992-byte memory is roughly nine times the MDS D124's capacity, useful where the application writes a full process history onto the tag instead of just an ID. The quick-change holder accessory lets the transponder be swapped without redrilling the M5 mount, which matters on fixtures that see frequent tag replacement in the heat-cycling range this part is built for.
