6.5 SIMATIC RF642A

Connecting the antenna

The SIMATIC RF642A 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.

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.
