■
Suitable drill holes for mounting the device as per the dimensional drawing: four
for M6 screws or three for M5 screws.
5.3
Mounting location
When selecting the mounting location, the following factors are significant:
•
Spatial working range of the antenna
•
Distance to objects with a transponder
•
Influence of the environment on the UHF field produced, for example:
°
Metal surfaces located to the side of and in the vicinity of the device
°
Electrically conductive liquids between the antenna and transponder
°
Persons between the antenna and transponder
5.4
Mounting the device
WARNING
Risk of injury due to damage to the device
For reasons of safety, if a device shows visible signs of damage do not put it into opera‐
tion, or take it out of operation immediately. Damage includes, for example:
•
Housing: Cracked or broken
•
Electrical connections: cracks or detachment from the housing
•
Device with fixed cable: Damage to the cable outlet or cable itself
NOTICE
Risk of damaging the device!
Observe the maximum screw-in depth of the blind tapped holes on the device. Longer
screws than specified damage the device.
b
Use screws of suitable length.
Basic arrangement of the device and external antennas to the transponders
UHF transponders have dipole antennas and therefore preferential directions when
transmitting or receiving within the radiation field of the antenna. The transmitting and
receiving performance will be higher or lower depending on the orientation of the dipole
antenna of the transponder to the axis perpendicular to the antenna surface. The read‐
ing and writing rate and sensing range can therefore be subject to fluctuations.
NOTE
If the dipole antenna of the transponder is oriented lengthwise along the axis perpen‐
dicular to the antenna surface, no reading or writing of the transponder will be possible.
