The 6GT2813-1FA00 is a SIMATIC RF660H ETSI UHF RFID reader module — the antenna and radio head for a UHF read station. It operates in the 865-868 MHz band at a maximum transfer rate of 400 kbit/s, with an equivalent isotropically radiated power adjustable from 9 to 400 mW. It is multitag-capable and uses linear polarization. The 1300 mm read range is the practical working distance for a UHF portal or conveyor gate; at 400 mW EIRP you get that range, and you can dial it down for zone control. This module is not standalone — it must be paired with the SIMATIC RF160B basic device (6GT2003-0FA00), which supplies power and handles the system interface. The interface is internal to the RF160B, so the reader head connects via a short cable to the basic device, which then talks to the controller over PROFINET or serial. The RF660H is designed for RF600 transponders and is approved for Europe under ETSI regulations.
Deployment context
The IP65 rating means the reader module handles washdown and dust ingress — suitable for conveyor lines, warehouse doorways, or outdoor sortation zones where moisture and debris are present. The operating temperature range of -20 to +50 °C covers most factory floor and logistics environments, while storage tolerance of -20 to +60 °C covers unheated warehouses. The module itself is compact at 85 mm wide, 52 mm high, and 27 mm deep — it mounts to a bracket or machine frame, not a DIN rail. Because the RF660H is only the antenna head, the RF160B basic device handles the power supply and network connection. That means the basic device goes in the panel or junction box, and the reader head mounts at the read point. The two are connected by a system-internal cable. Plan your cable run between the basic device and the reader head — the distance is limited by the cable type, not the reader module itself.
