The MKB104 series of rugged keyboards is designed to meet MIL-STD-461F standards and will provide the user a highly reliable input device for various critical applications. The keyboard is equipped with a high spec rubber dome key mechanism which ensures an excellent tactile feel and a life time of 10 million actuations. On the standard units, backlighting is powered over USB, but we can also offer the option for the backlighting to be externally controlled by the customers’ PWM signal. As with all NSI products, this unit can be customized to suit your exact needs. This not only includes the integration of different color or NVIS backlighting, but can also include adding or removing keys, different mounting arrangements or integration of a pointing device.
