3. Installation and wiring
The Reader Module is designed for installation on a heat sink. Mounting is accomplished using the
∅ 4.5 mm holes located in each corner of the base plate (see Fig. 3-1).
To fully exploit the performance of the Reader Module, the heat sink should have a thermal resis-
tance R
ThK
of max. 0.8 K/W. When attaching the Reader Module to the heat sink you should strive
for a little heat transfer resistance between the base plate and the heat sink as possible. The use
of heat sink compound is recommended.
If the antenna is properly tuned and there is sufficient air convection along the mounting plate, the
ID ISC.LRM200 can be operated without an additional heat sink at up to 4W of power. Note here
however that detuning of the antenna can result in additional heating of the Reader. In such cases
the Reader regulates its output power down until the upper temperature limit of its final stage is
reached again.
