Possible interference sources
It is possible that external interference sources will influence the read range, e.g.
CRT monitors, switching power supplies, power cables parallel to data cables,
mounting on metal etc.
In particular, the reader should be mounted on non-metallic material, such as plastic or wood. Metal screws
(M6 - ISO 1207, 4762 or 7045) for mounting the reader have an insignificant influence on the read range
and may thus be used.
With growing distance between reader and an interference source, the influence
decreases. Use only regulated power supplies. deister electronic GmbH offers suitable
power supplies. To reduce the influence of external electrical interference, connect
the cable shield to ground (GND) of the power supply.

Field Characteristics
The following diagram shows the read range of the LCA 500. Please note that the read range varies de-
pending on the position of the transponder as shown in the diagram below. The presence of any magnetic
material such as steel changes the given shape.
