With an industrial silicone rubber backlit keypad, the AK-4 series of keyboards is designed for use in rugged applications. Sealed to IP68, the AK-4 resists dust and water and is perfect for use in fixed and rotary-wing aircraft. An integrated mouse pointer enhances functionality while minimizing the overall size of the keyboard. The precision slides ensure smooth retraction of the keyboard when not in use. The AK-4 allows for a range of installation options with AeroComputers map systems and other compatible devices.
