GENERAL KEYBOARD SPECIFICATIONS Membrane Short travel MEMBRANE KEYBOARDS (KBM series)

Relatively long travel of 1,4 mm with distinctive tactile click
The higher pressure force (typ 4N) limits the data entry speed (not always a disadvantage for industrial applications)
Overall sealing up to IP65 static (opto-mechanical trackball)
Robust, field prooven technology

> 6 SHORT TRAVEL KEYBOARDS (KST series)

Short travel of 0,3 mm with tactile feel
Lower pressure force (typ 2.5N) allowing a higher speed of data entry
Overall sealing up to IP67 (panel mount versions)
Lower set up charges and lead times for new country versions as only the front foil needs to be changed
