ArgonFDS has developed small, lightweight and compact family of keyboards for rugged military environments. Our keyboards are resistant to penetrating materials such as sand, dust and liquids. A variety of keyboards can be selected for different languages, backlighting schemes, key force and travel.

The enclosure is made of bent, welded aluminum for the top assembly and a milled aluminum plate for a secure bottom plate that provides a solid base that is resistant to bending motions and can be bolted down. Pictured (right) is a compact version for table mount or stow away. The customer may select a variety of indicators or buttons depending on the application.

We provide an optional sealed pointing device, or the customer can specify.
