Read range and reader dependency
The Siemens 6GT2800-1CA00 RF320T transponder has a maximum read range of 60 mm, but that range is reader-dependent — the actual distance you get in your line depends on which RF300 reader head and antenna you pair it with. Siemens publishes a reader-specific range matrix in support document 67384964; for a procurement decision, budget 60 mm as the ceiling under ideal alignment and derate for off-axis or metallic environments.
Temperature envelope and sealing
This transponder operates during read/write access from -25 to +125 °C, with a wider storage range of -40 to +140 °C. The IP67/IPx9K rating means the epoxy-resin body and sealed construction survive high-pressure washdown and steam cleaning — suitable for food-and-bev or paint-shop lines where the tag sees both heat and aggressive cleaning cycles. The 27 mm diameter by 4 mm height button form factor mounts via M3 screw or gluing. The mounting support and spacer accessory (listed separately) helps align the tag in a recessed pocket so the reader gets a consistent air gap.
Memory and protocol specifics
Memory is organized as a 4-byte UID (fixed code) plus 20 bytes of user-accessible EEPROM with block-by-block write protection. The 13.56 MHz operating frequency and RF300-specific protocol mean this tag only works with Siemens RF300 readers. Transfer rate is 106 kbit/s maximum, and the tag is multitag-capable — multiple tags can be read in the same field if the reader supports anti-collision. No backup battery, so the EEPROM retains data passively.
