The Siemens 6GT2813-1FA20 is a SIMATIC RF660H CMIIT UHF RFID reader module, purpose-built for the Chinese market with CMIIT certification. This is not a standalone device — it is designed exclusively to be operated with the RF160B basic device (order code 6GT2003-0FA00), which provides the power supply and system interface. Operating in the 920 to 925 MHz UHF band with linear polarization, it delivers a read range of 1300 mm and a maximum transfer rate of 400 kbit/s. The equivalent isotropically radiated power (EIRP) is adjustable from 9 to 400 mW, giving flexibility to tune the read zone for different tag densities and mounting heights. The IP65-rated housing (27 mm deep, 85 mm wide, 52 mm tall) means it withstands washdown and dust ingress on the factory floor — suitable for conveyor lines, portal gates, or warehouse dock applications where the basic device is mounted in a nearby enclosure.
Because it is a region-specific module (CMIIT for China) tied to the RF160B basic device platform, sourcing is straightforward for new installations or as a critical spare for existing RF660H deployments. We quote this part to order against an RFQ; lead time depends on the basic device availability and the reader module's production batch.
Integration constraints
The reader module communicates via a system-internal interface to the RF160B basic device — there is no standalone fieldbus port on the module itself. All power and data routing goes through the basic device, which handles the connection to the control network (PROFINET, Ethernet/IP, or serial depending on the RF160B variant). The multitag-capable feature means it can read multiple RF600 transponders in a single interrogation field, which is useful for pallet-level or tote-level tracking where several tags pass the antenna simultaneously. The 1300 mm range is the maximum under ideal conditions; real-world range will vary with tag type, mounting material, and local RF interference in the 920-925 MHz band.
