PM1420 Industrial PCAP Touch Controller Board

As industrial touchscreen applications become more demanding, choosing the right touch controller is just as important as selecting the display panel. Glove operation, wet-touch performance, multi-touch capability, and reliable operation in harsh environments are increasingly important for industrial HMI systems.

The PM1420 Industrial PCAP Controller Touch Control Board, powered by the iBLab S1104 capacitive touch controller, is designed for 12.1 to 15.6-inch projected capacitive (PCAP) touch panels. It supports glove touch, wet touch, air gesture, and pencil input, making it suitable for a wide range of industrial touchscreen applications.

With high touch sampling rates, low response time, wide operating temperature support, and industrial EMC immunity, PM1420 provides a flexible touch control solution for demanding applications.

Designed for Demanding Industrial Touchscreen Applications

Industrial touchscreen systems often operate in environments where standard consumer-grade touch solutions may not provide sufficient reliability. The PM1420 addresses several common requirements in industrial equipment.

Glove and Wet-Touch Operation

Operators in industrial environments may need to use touchscreen equipment while wearing protective gloves or working in areas exposed to moisture.

PM1420 supports glove and wet-touch operation, helping maintain touchscreen usability in challenging working conditions.

This makes it a potential solution for:

• Industrial control panels
• Factory automation equipment
• Medical equipment interfaces
• Outdoor industrial terminals
• Food processing equipment

High-Speed Multi-Touch Performance

With sampling rates of up to 165Hz for single-finger input and 130Hz for 10-finger input, PM1420 supports responsive multi-touch interaction.

Its average response time of less than 30ms helps provide smoother touch operation for industrial HMI applications that require accurate and timely user input.

The 4096 × 4096 firmware resolution also supports precise touch positioning.

Reliable Operation in Harsh Environments

Temperature fluctuations, electromagnetic interference, and high humidity can affect touchscreen performance in industrial systems.

PM1420 offers a wide operating temperature range of -40°C to +85°C and supports 95% RH humidity at 60°C.

Its IEC 61000-4-3 and IEC 61000-4-6 Level 3 EMC immunity capabilities provide additional support for industrial applications where electromagnetic compatibility is important.

A firmware-programmable watchdog timer further helps improve system reliability.

Flexible Host System Integration

Different industrial equipment platforms require different communication interfaces.

PM1420 provides three interface options:

• USB Full-Speed at 12Mbps
• UART at 38400 baud
• I²C slave interface at 400kHz

These interfaces offer flexibility when integrating the touch controller into industrial computers, embedded systems, and HMI platforms.

Actual interface compatibility should be verified with the host hardware and system software before integration.
