scissor switchwith Fn key90-key

Product Description

• 90-key ultra-thin patented scissor-switch keyboard with integrated ultra-thin Flexible Printed Circuit.
• Fully sealed, waterproof front panel (IP67) with aluminum alloy front frame to reinforce structure and prevent deformation.
• Integrated fully sealed, wide-temperature touchpad (400 DPI) with two mouse buttons (left and right).
• Adjustable white backlight; 12 function keys (F1–F12) on the top row. FN + LOCK key combination allows cleaning without removing the keyboard.
• Scissor-switch design: 1.20 mm ±0.10 mm key travel, good tactile feedback, fast and quiet operation. Pry-resistant keycaps reduce key loss, stuck keys or repeated input.
• Durable coating and antimicrobial surface resistant to common chemicals and liquids in harsh environments.
• Designed to meet MIL-STD-810H (wide temperature, low pressure, humidity, vibration, shock, temperature shock, rain, salt mist, dust, fungus, solar radiation, etc.); MIL-STD-461G EMC/EMI/EMS/ESD optional.
• Patent: 202422198937.6.

Applications

• Vehicle, aerospace, naval and maritime systems
• Radar and display consoles
• Portable rugged laptops and field equipment
• UAV ground stations and other electronics for harsh environments
