resistive touch screens allow for choice of user input via finger, gloved
finger or stylus. This is in contrast to capacitive touch screens where the
only reliable input is via a non-gloved finger. Resistive sensing is the
technology of choice for critical applications.
Series touch screens provide engineers with the flexibility to handle many
applications. Customization options include screen size, film choice, glass
thickness, material combination, tail type and location, number of keys (on
digital models) and integration of monitors and touch screens together.
Five wire models are useful for larger screens used on
larger equipment. For portable applications and mobile devices, NKK has taken the long screen life of
5-Wire technology and the lower power consumption of 4-Wire technology and
combined it into its latest enhanced 4-Wire designs.
All models in the FT Series are
toughened with films and coatings to avoid scratching and environmental
deterioration. Film surface comes standard with non-glare and hard coated
treatment for ease of use and maintenance of surface integrity. An optional
film which eliminates fingerprints is also available.
Visual artifacts are eliminated via anti-Newton ring film.
Screens are also resistant to static electricity and noise pollution. They
feature high touch point density, translating to more precision, the reduction
of false actuations and quicker response times. Temperature fluctuations do not
affect the drift-free operation.
digital FT Series touch screen is designed to replace a pushbutton panel or
keypad when more complex tasks such as drawing are not required.
Touch screen controller boards and drivers for these devices
are available from NKK for USB and RS232C communication requirements. NKK touch screens
are compatible with Windows 7, Windows Vista, Windows XP and several legacy
Windows operating systems.
IC chips are offered for the 5-Wire and 4-Wire touch screens
for engineers who prefer to design their own controller boards. These chips
provide high speed and accuracy. Receptacle connectors can be ordered
