What Challenges Are Posed by an Industrial Environment?
Reliability is the foremost concern for IPCs. PCAP touch panels in IPCs are normally surrounded by requisite equipment such as transformers, control motors, robot arms, etc. These devices generate high voltage and noise interference in different frequency bands. In addition, poor grounding design will also generate high noise interference, IPCs must pass a number of safety certifications, and operators frequently need to wear gloves during operation.
How reliable are AMT Industrial PCAP Touch Panels?
The signal generator outputs 150V 8kHz low frequency noise interference to simulate noise from a control motor. When this signal is applied to the two display units, the unit with PenMount noise handling technology can be operated normally and is not influenced by the interference. False touches can be seen on the other unit.
AMT PCAP touch panels utilize noise filter hardware to eliminate most noise interference in high frequency bands and SNR for signal detection to allow the control board to differentiate noise interference and touch signals in a timely manner. Then, PenMount’s proprietary frequency hopping algorithm automatically selects the most suitable operating frequency to enhance anti-noise interference performance.
AMT PCAP total touch solutions have passed the following EMC test items:
● IEC 61000-4-3: Radiated Susceptibility (RS) Level III 10 V/m, Criteria “A”
● IEC 61000-4-6: Conducted Susceptibility (CS) Level III 10 Vrms, Criteria “A”
Meeting the Challenges of IPC
Standard AMT touch products support operation while wearing a wide selection of glove types to protect operators from machines and the environment. A harsh environment also means that the touch panel itself may need to be ruggedized. AMT touch panels support a number of cover lens thicknesses from 4mm, 6mm, to a maximum of 10mm for the best impact resistance.
