©KRAI SMSH (Smart Shelf) Antenna
Fig. 4: ©KRAI smart shelf antennas connected to the reader (cascaded)
Up to 8 ©KRAI smart shelf (SMSH) antennas can be cascaded per reader port; 8 antennas x 4 ports = 32 SMSH antennas
in total.
T
he SMSH 3030 @KRAI slave antenna was developed for applications in the field of point of sale, smart shelf applic
a-
tions and Kanban solutions. The antenna is characterised by an extremely homogeneous read zone, which is emitted by
the high front-to-back ratio. Therefore, it is suitable for static detection of multiple transponders. Due to the extremely
thin design, the antenna module can be integr
ated into differ
ent applications.
The antenna is equipped with an intelligent bypass circuit that allows for cascading up to 8 SMSH antennas per reader
port. The contr
ol is done by a RRU 4xxx Kathr
ein RFID reader. The ©KRAI control signals are transmitted via the standard
antenna cable.
