Connecting the antenna

The SIMATIC RF620A antenna must be connected to the reader using an antenna cable.
Preassembled standard cables in lengths of 1 m, 3 m, 5 m, 10 m, 15 m, 20 m and 40 m are
available to connect the antenna.
The range of the antenna is limited by the cable loss. The maximum range can be achieved
with the cable 6GT2815-0BH10 (length 1 m), since this cable has the lowest cable loss.
Requirement
Note
Use of Siemens antenna cable
To ensure optimum functioning of the antenna, it is recommended that a Siemens antenna
cable is used in accordance with the list of accessories.
Strain relief
To protect the antenna connecting cable from strain, you can attach strain relief, e.g. in the
form of a strain relief clamp. The following graphic shows the optimum mounting point for
attaching strain relief.

Bending radii and bending cycles of the cable

The following listed bending radii are minimum values, which may not be fallen below and
are based on repeated bending.
