8.2. Installation notes
Be aware of the following possible environmental factors when installing an ID MAX50.10-E into
another device :
• Effects from nearby metal objects
⇒ Detuning of the integrated antenna
⇒ Impaired communication 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
8.2.1. 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 MAX50.10-E into another device, be sure therefore that a clean, noise-free
power supply is used.
8.2.2. EMC effects from magnetic fields
The communication principle of RFID- Technology is based on the modulation of electromagnetic
fields. Alternating magnetic fields in the vicinity of the antenna can have a negative influence on
the reader function.
Sources of such magnetic interference fields include coils within a primary or secondary switching
power supply.
