Solid-State HMI

Next-generation touch control for severe cleanroom and industrial environments

Designed for hospitals, food packaging lines, public info terminals, and smart home dashboards - delivering chemical-proof, fully flat panels where mechanical switches would fail or collect dirt.

Solid-State Reliability

No moving mechanical components. Eliminates switch wear, spring fatigue, and key stuck issues, guaranteeing a virtually infinite operational lifespan.

Proximity Detection

Integrated proximity sensors detect approaching hands up to 10cm away to wake the control panel from sleep mode or light up key indicators.

Tactile Haptic Confirmation

Onboard vibration actuators and configurable buzzers deliver immediate physical confirmation on keypress, resolving the lack of travel feedback.

Hermetically Sealed Design

The completely flat front panel meets IP67/IP69K sealing grades. Leaves no seams for dust or bacteria, allowing sanitization with aggressive agents.

Smart Auto-Calibration

On-chip auto-tuning algorithms dynamically adjust sensitivity thresholds, adapting to surface moisture, dirt buildup, or glove thickness variations.

Multi-Interface Support

Supports low-level communication protocols like I2C, SPI, and Modbus RTU, communicating state and configuration data directly to central controllers.

Precision Touch Engineering

Complete touch integration for harsh environments

Eliminate traditional mechanical panel wear. Smart touch switch matrices can be calibrated to operate through thick wood, stone, glass, or acrylic panels. Designed for cleanrooms, sterile healthcare suites, marine bridges, and high-abuse outdoor ticketing machines.

  • Chemically strengthened cover panels up to 6mm thickness
  • Configurable touch sensitivity thresholds per sensor zone
  • Multi-color RGB lighting rings with customizable blink animations
  • Complete protection against electrostatic discharges (ESD) up to 30kV

HMI Integration

Direct interfaces for industrial systems

I2C
I2C Bus Link

Direct digital link to microcontroller units for low-overhead multi-key readings, reducing wire count to host boards.

HAP
Haptic Feedback

Onboard driver coordinates immediate micro-vibrations for a crisp 'press' simulation upon contact.

PROX
Proximity Antenna

Integrated copper trace ring maps hand presence to wake system displays and brightens local controls.

ESD
Extreme Isolation

Insulating cover overlay prevents static shock pathways to the internal circuitry, ensuring ESD immunity up to 30kV.
