Siemens is expanding its Simatic RF600 RFID product range with transponders that have more memory capacities and a compact mobile read-write device. They are for use in distributed configurations for example in production control, asset management and intra-logistics.
With a capacity of 4kbyte, theSimaticRF622T and RF622L UHF RFID data carriers enable large volumes of data to be stored on tagged objects as well as facilitating rapid access to them. The Simatic RF650M mobile handheld reader enables reliable identification of a large number of transponders at a range of up to three meters. The device is designed for logistics and service applications.
The FRAM (ferroelectric random access memory) technology of the RF622T and RF622L transponders enables high-speed writing as well as an unlimited number of write cycles. The RF622L is a cost-efficient smart label that is suited to the permanent identification of products. It can be individually printed from a roll, for example with plain text or additional optical codes. In contrast, the robust and hardened RF622T transponder has been designed for fixing to pallets or containers. It can be attached to metal surfaces with the optional spacer.
The dimensions of the RF622T transponder are 120 by 30 by 6.5mm, and those of the RF622L smart label are 90 by 18 by 0.5mm.
The handheld RF650M has a colour touch display with a resolution of 240 by 320 pixels, a rugged keypad and a large trigger button. These ensure reliable and user-friendly operation. To save space, users can fold down the RFID antenna. The device dimensions of 147 by 60 by 39mm mean it can be carried in a pocket and its weight of 235g, including the rechargeable battery, allows fatigue-free use over long periods.
The battery has a life of up to nine hours, ensuring the device is supplied with power for at least the length of one shift. Users can also create their own applications for the device based on the Microsoft Windows Embedded operating system. For servicing work, the supplied RFID software can also be used for reading and writing from and to transponders. This means transponders are easy to read or re-programme for test purposes, during maintenance work for example.
