Read/Write Devices

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.
Communication between MDS and SLG takes place via inductive alternating fields.
The amount of data which can be transferred between SLG and MDS depends on the factors listed below.
S The speed at which the MDS moves through the transmission window of the SLG
S
The length of the transmission window
S
The type of MDS (i.e., RAM, FRAM, EEPROM)

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.
