An essential requirement of industrial touchpanels is the EMC compliance. Other electrical equipment in the near vicinity should not disturb the operation of your product and it should also not disturb other equipment.

Sources of interference in accordance with IEC standard

To obtain an EMC stable input system two main sources of interference have to be considered. The first source of interference are the displays which have to be integrated behind the touch panel and the power supplies being clocked. The EMC standard IEC 61000-4-3 refers to these interference sources.

Furthermore, the EMC standard IEC 61000-4-6 defines Conducted Coupling of interfering voltage peaks and frequencies. To eliminate these interference signals that the HMI system operates with positional accuracy without deviation of the touch function. This in turn does not cause false alarms and is a prerequisite for achieving EMC compliance to Class A.

Technical solution

With optimized AD converters in the evaluation electronics of the PCAP controller, increased signal voltages through charge pumps, special algorithms (frequency-hopping method and hardware/software filters) and interference sources can be suppressed comprehensively. With a sensor design specially adapted to the electronics, additionally an optimum signal-to-noise difference is achieved.

In the video you will find a test for the EMC certification.

EMC testing

Your product should comply with the European EMC standards and regulations. Prior to the final EMC test at an accredited test lab, it is recommended to investigate the EMC behaviour at the early design phase by performing pre-compliance tests. This can be done by yourself or with the assistance of SCHURTER Input Systems.

The following EMC standards have been met successfully

IEC 60601-1-2: Edition 4.0

IEC 61000-4-3: Level III, 10 V / m, up to 28V / m @ 385 ~ 6000MHz

IEC 61000-4-4: Test Electrical Fast Transient / Burst Immunity. Level III, Vpp ± 2 KV

IEC 61000-4-6: Conducted Radio Frequency Immunity, Level III, 10V / m

Your SCHURTER EMC competence center

SCHURTER has its own competence center with testing equipment for assessing conductive immunity. While testing during an Competences

of the development phase, possible EMC issues can be recovered. That gives more confidence in succeeding on the final (expensive) EMC tests the first time and this of course is cost-effective.
