Antennas
6.7 RF680A antenna
6.7.3 Installation
VESA 100 mounting system
A standardized VESA 100 mounting system is provided to mount the antenna. The mounting
system consists of four fixing holes for M4 screws at intervals of 100 mm.
This is therefore suitable for:
● Mounting on metallic and non-metallic backgrounds
Note
Reaching an optimum wave propagation
To achieve optimum wave propagation, the antenna should not be surrounded by conducting
objects. The area between antenna and transponder should also allow wave propagation
without interference.
Antenna mounting kit
The Antenna Mounting Kit allows the fine adjustment of the antenna field by setting the solid
angle.
6.7.4 Connecting the antenna
The SIMATIC RF680A 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.
NOTICE
Connecting the antenna
Do not connect the adaptive antenna RF680A during operation. Only connect the antenna
to a reader that has been turned off and then restart the reader.
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 has the lowest cable loss.
Requirement
Note
Use of Siemens antenna cables
To ensure optimum functioning of the antenna, it is recommended that a Siemens antenna
cable be used in accordance with the list of accessories.
