Ultra-Low Profile HMIs

Ultra-Thin Keyboard

State-of-the-art, ultra-thin HMI keyboards and low-profile keypad overlays. Engineered at a thickness of under 1.5mm, these interfaces integrate stainless steel tactile metal domes, flexible printed circuitry (FPC), and robust protective overlays. Perfect for space-constrained medical, military, aerospace, and high-reliability industrial setups.

Precision Low-Profile Panels

High reliability engineered into a fraction of a millimeter

Designed for space-critical controls where thickness, weight, and mechanical footprint are limited without sacrificing tactile click response or environmental sealing.

Ultra-Low Profile Design

Overall switch stack thickness between 1.0mm and 1.5mm minimizes housing depth requirements in portable instruments.

Tactile Metal Domes

Embedded stainless steel metal dome array provides distinct mechanical snap feedback under fingers.

Hermetically Sealed Layout

IP67 ingress protection against dust, water, grease, and aggressive sanitizing agents in harsh environments.

Flexible Printed Circuits

High-density copper FPC backing circuit offers tight bend radius tolerances and maximum signal path integrity.

Custom Graphic Polyester

Embossed borders, matte/gloss textures, and corporate branding silkscreened onto chemical-resistant polyester overlays.

Integrated SMD LEDs

Extremely flat surface-mount LEDs (under 0.5mm height) embedded inside the film layers for clear status signals.

Space-Saving HMI Engineering

Precision design for space-critical interfaces

Space constraints shouldn't compromise tactile feedback or long-term durability. Keetronics ultra-thin keyboard panels stack active tactile metal dome layers, flexible circuits, and shielding films into a durable unit under 1.5mm thick. Trusted in handheld medical monitors, military rugged tablets, and aerospace cockpit dashboards.
