5.5 SIMATIC RF685R
5.5.1 Description
5.5.1.1 Overview
The SIMATIC RF685R is a stationary reader in the UHF frequency band with an integrated
antenna. An additional external UHF RFID antenna can be connected via an RP-TNC
connector.
The maximum transmit power is 2000 mW at the external reader output. A radiated power of
up to 2000 mW ERP / 4000 mW EIRP is achieved when the appropriate antennas and
antenna cables are used. The interfaces (Ethernet, power supply, DI/DQ interface) are
located on the lower front edge. These interfaces can be used to connect the reader to the
power supply and to a PC or a controller for parameter assignment.
The degree of protection is IP65.
