8.5. Installation notes

Be aware of the following possible environmental factors when installing an ID ISC.M02 into an-
other device :
•
Effects from nearby metal objects
⇒ Detuning of the integrated antenna
⇒ Impaired propagation of the antenna's magnetic field
•

EMC effects on cables

⇒ Impaired communication between reader and transponder
•
EMC effects from magnetic fields
⇒ Impaired communication between reader and transponder

8.5.1. Metallic surroundings

When installing an ID ISC.M02 into another device, be sure that there are no metal surfaces or
objects in the direct vicinity of the reader if possible. These can detune the antenna and thus re-
duce the magnetic field of the integrated antenna. This will in turn result in reduced read distances
for the reader.
The distance between the reader and a metal surface should be at least 3 cm. Note that
even other circuit boards may act line metal objects depending on how much copper they
contain.
If a metallic surrounding cannot be avoided, stable function should at least be ensured by keeping
the distance as great as possible.
The area between the antenna and transponder as well as the area on the other side of the trans-
ponder should also be kept clear of metal parts.
Since any change in the metallic environment will result in detuning of the integrated antenna and
therefore to impaired function, no moving metal parts, such as metallic fans, should be allowed in
the vicinity of the reader.
8.5.2. EMC effects on cables
In spite of the internal EMC filters inside the reader, high levels of noise on the supply voltage can
result in impairment of the communication between the reader and transponder.
When installing an ID ISC.M02 into another device, be sure therefore that a clean, noise-free
power supply is used.
