Siemens 6GT2810-3HC80 SIMATIC RF620 RF620T Mount-on-Metal UHF RFID Transponder

The Siemens 6GT2810-3HC80 is a SIMATIC RF620T UHF RFID transponder for mount-on-metal applications, built for the 860 to 960 MHz frequency range with a 256-byte user memory. Measuring 127 x 38 x 6 mm with IP67 sealing, it withstands storage and read/write temperatures down to -40 degrees C and operates on metallic asset surfaces where standard tags would detune.

Selection Notes

The 6GT2810-3HC80 is built for direct attachment to metal, so it skips the mounting standoff a standard UHF tag needs to avoid detuning near conductive surfaces. Its 12 mm minimum mounting distance figure applies to nearby metal beyond the tag body itself, not the mounting surface. With a 256-byte user memory and an EPC field expandable to 448 bit, it can hold more than a serial number, such as a short asset record, which is useful when a reader cannot always reach the host system for a lookup. Laser inscription on the tag body gives a human-readable backup identifier alongside the RF data.
