iKey’s rugged AK-39-NV keyboard is designed to be worn on the arm, providing a simple, compact data-input solution that does not restrict the user’s arm movements. It is designed to meet MIL-461 standards and is intended for use in very harsh electro magnetic interference (EMI) environments. The AK-39-NV’s small-footprint design features essential components for military and public safety applications, including an integrated Force Sensing Resistor (FSR) pointing device with left- and right-click functionality. The AK-39-NV also features six levels (including off) of adjustable green B LED backlighting that is night vision (NVIS) compatible. Designed with gloved users in mind, the AK-39’s snap-on faceplate eliminates accidental key strokes and can be easily removed to clean the pad.
