The CK78A is our new generation of hygiene keyboard series, which is specifically designed for the use in hospitals and healthcare applications. It has a compact layout. The silicon membrane protects the key field against ingress of dirt and fluids. The CK78A impresses with its low force key actuation and precise key guidance. It is highly recommended for heavy duty type writing in hygiene-critical environments, particularly for office and administration applications. Additional benefits are: 

  • Thorough surface disinfection by spray/wipe sanitizing on flat keyboard skin without edges and seams. 
  • Clean Function allows for disabling the keyboard during cleaning (“Fn”+”Clean”). 
  • Suitable for most common hospital disinfecting solutions
  • Replaceable keyboard skin for clinic disinfection by steam pressure processing
  • Touch proof disinfection of the surface of the keyboard body by spray/wipe sanitization
  • Surface disinfection instead of invasive submersion cleaning:
    • Avoids outer and inner re-contamination by polluted suds
    • No risk of germ transmission by fluids leaking or dripping off the product
    • No contact with hollow spaces
