For design-oriented applications and input devices N & H Technology offers capacitive keyboards. They are realized by an electrically conductive surface, such as glass, metal or plastic.
These capacitive sensors simulate the input fields. The change in capacitance of the electric field takes place by touching or approaching the finger. Unlike the keypad no tactile feedback takes place. However, these can be replaced by an acoustic or optical signal. Capacitive Keyboards can be made in various keys forms and shapes. Operating modes such as Slider, Wheel and touchpad can be added.
Metal over Capacitive (MOC)
Through a new, touch-sensitive sensors, capacitive input solutions with metal fronts made of stainless steel or aluminum are possible. A very sensible sensor recognize a deformation of the surface. It can be used with gloves and is extremely resistant to environmental influences. Plastic surfaces or combined surfaces of plastic and metal are possible.
In the area of touch panel we provide all current technologies , both as a standalone solution or in direct combination with our displays and as an integrated solution with membrane keyboards or as an assembly consisting of an LCD display , touch screen and hardened design front glass .
