Product catalog summary

Product Description: The K-TEK-M276KP-BL-ML-OEM is a 62-key IP65 dynamic sealed and ruggedized silicone rubber military keyboard. It features an industrial PCB and lacks 12 function keys and a numeric keypad. The keyboard uses carbon-on-gold key switch technology with a long stroke of 1.50mm, providing excellent tactile feedback for fast and accurate data input without noise. It has a durable coating and an anti-microbial surface that withstands most chemicals and liquids in harsh environments. Optional backlight side function keypads are available.

Compliance and Standards: The keyboard is designed to meet MIL-STD-810F standards, covering aspects such as temperature extremes, pressure, humidity, vibration, shock, and more. It optionally meets MIL-STD-461G standards for EMC, EMI, EMS, and ESD. It adheres to critical military standards in reliability, safety, maintainability, testability, supportability, environmental adaptability, stability, compatibility, consistency, and continuity.

Mechanical Data: The keyboard measures 276mm x 65mm and weighs 0.80KG. It features protuberant rectangular keys with tactile feedback, with normal keys measuring 12.0mm x 13.0mm and the enter key measuring 22.5mm x 13.0mm. Key travel is 1.5mm±0.1mm, and actuation force is 1.5N±0.2N. The switch life exceeds 5 million operations.

Electrical Data: The keyboard operates on a DC +5V±5% supply voltage, with a current rating of 30mA when the backlight is off and 300mA when on. It complies with EMC standards EN 55032:2015 and EN 55035:2017. The lifespan is over 5 years, and it uses carbon-on-gold key switch technology with a gold PCB. Interfaces available are PS2 and USB, with a standard cable length of 2.0m, customizable upon request. It is compatible with all Windows, Linux, Unix, Mac OSX, Vxworks, and Android (U-cos to be confirmed).

Environmental Adaptability: The keyboard operates in temperatures ranging from -40℃ to +75℃ and can be stored between -45℃ and +85℃. It functions at 100% relative humidity and atmospheric pressures of 60-106Kpa. It withstands saline mist for 96 hours and passes damp heat and dry heat tests as per IEC 60512-6 standards.

Reliability: The keyboard is RoHS compliant and CE and FCC certified. It meets MIL-STD-810F standards for various environmental conditions. It has an IP65 dynamic protection level for the front panel, a key lifespan of over 5 million actuations, an MTBF of over 20,000 hours, and an MTTR of less than 30 minutes.
