Capacitive Touch HMI Solutions

CapSense Capacitive Keyboard

A sleek, solid-state HMI input device designed with zero-travel capacitive touch sensing. Built with rugged glass, acrylic, or polycarbonate front panels, it features advanced water rejection, glove compatibility, and tactile haptic feedback - offering a completely flat, hygienic, and wear-free user interface.

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 Touch (Zero Wear)

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

Thick Overlay Penetration

Advanced capacitive sensing penetrates up to 6mm of cover glass or 4mm of plastic, enabling fully sealed, impact-resistant structures.

Advanced Water Rejection

Specialized firmware rejects inputs from water droplets, condensation, or heavy sprays, preventing false actuations while remaining responsive to touches.

Hygienic Wipe-Clean Surface

The completely flat front panel leaves no cracks, joints, or bezels for bacteria or dirt to collect, allowing quick, total washdowns with aggressive disinfectants.

Haptic & Audio Feedback

Integrated vibration motors and buzzer circuits deliver immediate physical and audio confirmation upon a keypress, resolving the lack of travel feel.

Customized Graphic Overlays

Printed on the backside of cover panels, ensuring key legends, brand logos, and warning icons never wear off, fade, or scratch during daily heavy use.

Flexible interfaces for HMI integrators

USB
USB & Serial Links

Transmits standard USB keyboard codes for driverless integration, with direct I2C or SPI output options for embedded systems.

TUNE
SmartSense Auto-Tuning

Dynamically adjusts switch thresholds to adapt to condensation, overlay wear, and ambient temperature shifts automatically.

LED
Individual Key Backlight

RGB or single-color LEDs provide illuminated key frames that can change state upon click or stay constantly lit.

ESD
High ESD Isolation

As the circuit sits completely behind a thick insulating overlay, it provides absolute protection against ESD up to 30kV.
