What the 1300 mm range means for your read zone
The Siemens 6GT2813-1FA10 SIMATIC RF660H is an FCC-compliant UHF RFID reader module for the North American and Canadian markets, operating in the 902 to 928 MHz band. Its 1300 mm read range defines the practical antenna-to-tag distance in a fixed installation — you can reliably interrogate RF600 transponders out to roughly 1.3 m line-of-sight, which covers most conveyor gate, dock-door, or portal applications without needing a separate antenna. The module draws power and data connectivity exclusively through the RF160B basic device (6GT2003-0FA00); it has no standalone interface, so the basic device is a mandatory line item on your BOM, not an option.
IP65 and washdown tolerance — where it mounts
That qualifies it for washdown environments, outdoor staging areas under roof, and production lines where coolant mist or washdown spray is routine. The linear polarization means antenna orientation relative to the tag matters; align the reader's polarization axis with the tag's antenna plane for best coupling.
