SLG 42
Application area The SLG 42 is a middle-of-the-line read/write device. With its larger antenna, the SLG 42 generates a much larger field than the SLG 41, and a greater range can be achieved with the same data memories. In dynamic operation, larger amounts of data can be read from and written to the MDS.
