Read/Write Devices 5.1 Introduction Application area The read/write devices (i.e., SLGs) provide inductive communication with the mobile data memories (i.e., MDSs) and the serial link to the interfaces (i.e., ASMs). Various SLG models – for short, medium and long distances to the MDS – are available to meet customer requirements. Layout and functions The SLG executes commands received from the interface. These commands for reading and writing data are converted via a modulator/demodulator circuit.
Read/Write Devices 5.2 SLG 40 Application area The SLG 40 is extremely suited for use on small assembly lines. The short installation distance between several SLG 40 antennas is a special feature. With the 2 included screw nuts, the antenna head can be positioned with extreme precision for each application.
