What this tag is and where it fits
The Siemens 6GT2810-2HC81 is a SIMATIC RF620T container tag — a rugged, IP67-rated UHF RFID transponder built for the RF600 reader system. It operates across 860 to 960 MHz (covering global UHF bands) and complies with EPCglobal Class 1 Gen 2 and ISO 18000-63 protocols, so it talks to any standard UHF reader that speaks those protocols. The tag carries an IMPINJ MONZA 4QT chip with 128-bit EPC memory (expandable to 128 bit) and 64 bytes of user memory, plus a 32-bit TID. That user memory is useful for storing lot numbers, maintenance history, or a second identifier alongside the EPC. Read range is listed at up to 8 m, but that's reader-dependent — the system manual (RF600) is the authority for actual performance in your layout. Overrange is possible, so don't treat 8 m as a hard ceiling.
Physical fit and mounting
Dimensions are 127 mm deep × 38 mm wide × 6 mm tall — a slim, rectangular form factor that mounts via gluing, two M5 screws, or the optional spacer kit. The polypropylene (PP) body in anthracite is laser-engravable for your own asset numbering. IP67 means the tag survives washdown, dust, and temporary immersion — suitable for container tracking, pallet ID, or outdoor asset tagging where moisture and dirt are the norm. Shock resistance meets DIN EN 60721-3-7 Class 7M3 at 1000 m/s², and vibration resistance is 500 m/s², so it holds up on forklift-mounted containers or conveyor pallets.
Environmental limits and memory handling
Read/write temperature range is -25 to +85 °C; outside read/write access it survives -40 to +85 °C. Storage range is -40 to +80 °C. That covers most industrial and outdoor environments short of foundry or cryo. Memory is EEPROM with lock, unlock, write protection, and password protection features. No backup battery — it's passive, powered by the reader field. Multitag-capable, so you can read multiple tags in the field simultaneously.
Lifecycle and sourcing reality
cULus approval is listed, so it's accepted for installations requiring UL recognition in the US and Canada. No IECEx rating — not certified for explosive atmospheres.
