SLG 75
Application area SLG 75
The SLG 75 ANT is a read/write device in the middle of the performance range. It can only be used with ANT 1, ANT 12, ANT 18 and ANT 30. The antennas can be very easily positioned for any application.
The cable between the antenna and evaluation unit is 3 m long. The length cannot be changed.
The antenna cable can be connected on the SLG side.
The SLG 75 can be used with the following interface modules:
ASM 400, ASM 410, ASM 424, ASM 450, ASM 452, ASM 454, ASM 470,
ASM 473 und ASM 475.
Areas of application of the antennas
Figure 5-16 Read/write device SLG 75
ANT 1
Figure 5-17 ANT 1 for SLG 75
The ANT 1 is an antenna in the middle of the performance range which is very useful in production plants and assembly lines because of its easily handled housing.
The antenna’s dimensions make it possible to read/write large volumes of data from/to the MDS during operation. The antenna cable can be connected on the SLG side.

ANT 12
Figure 5-18 ANT 12 for the SLG 75
The ANT12 is intended primarily for tool identification. The very small size of the antenna permits very accurate positioning using the plastic nuts included with it. The antenna cable can be connected on the SLG side. Data carrier communication is only possible with the MDS E623 (tool pill) in static mode.
ANT 18
Figure 5-19 ANT 18 for the SLG 75
The ANT 18 was designed primarily for use in small assembly lines. The small, compact dimensions of the antenna with its two plastic nuts (included with the product) make it easy to position for any application. The antenna cable can be connected on the SLG side. Data carrier communication is only possible with the MDS E624 in static mode.
ANT 30
5-16
Figure 5-20 ANT 30 for the SLG 75
The ANT 30 was designed primarily for use in small assembly lines. The maximum read/write range is approximately 60% greater than the ANT 18.
The compact dimensions of antenna with its two plastic nuts (included with the product) make it very easy to position for any application. The antenna cable can be connected on the SLG side. Data carrier communication is only possible with the MDS E624 in static mode.
