This system is the most rugged available and as such is suitable for all public-access type applications from 8.4” to 20”.

A fine grid of wires is embedded onto the rear of the screen which generates an electric field. The controller is built onto one edge of the screen and draws it's power from the serial port. A touch to the front draws current towards the finger and the software calculates the touch position.

As the touchscreen is laminated with a piece of plain, toughened glass on the front (up to a thickness of 25mm) this is simple to seal to very high IP ratings and is the most impervious to damage. Even when the glass is scratched or damaged the touchscreen will still operate. This is the most appropriate system for medical and food industry equipment.

As the touchscreen can be calibrated also to operate different distances from the rear wire grid, it can be set up to operate through shop windows or other filters placed in front and can be calibrated to be sensitive enough to read a touch through gloves.

The touchscreens are available with anti-glare or plain finishes and can also be screen printed if required.
