Ordering information about the antenna and its accessories (mounting bracket and adapter
cables [N male connector / TNC reverse] of different lengths) is available on the following
SICK product pages on the web:
www.sick.com/6034316
The corresponding power loss values of the cables in the frequency band of 860 MHz to 960
MHz are also listed there.
Mounting
If several antennas are used in a reading station, e.g. two on each side of a conveyor sys-
tem, make sure that the antennas are not directly facing each other, but are installed at
staggered parallel positions.
Fixed wall-mounting (alignment not adjustable):
1. Mark and drill four fixing holes in the installation surface in accordance with the dimen-
sional drawing.
2. When installing on a plate or frame, insert the supplied bolts from the rear through the
installation surface and tighten the antenna.
Installation to a tube (alignment adjustable in two axis):
Use the mounting bracket no. 5321692.
1. Tight the bracket to the antenna (step 1).
