Key benefits • usage with protective glass up to 1cm thickness • multi-touch function • usage with gloves (latex, leather, rubber) • maximising the range of utilisation • high transmission ratio of 90% • automatic calibration & drift compensation (freely definable) • extended temperature range (-20°C...+70°C) • excellent EMC and EMI behaviour • high flexibility integrating the touch controller • low power consumption (5V x 20mA) independent of the size of the touch panel 2
Function • The touch sensor consists of a multilayer ITO-foil(indium tin oxide) • Couples of electrodes generate an electrical field. • When a finger touches the panel the field coupling will change. The controller will detected the change and calculate the position.
Y5 Y4 Y3 Y2 Y1 Y0 X0 X1 X2 X3 X4 X5 X6 X7 Definition of the touch-area • X and Y-lines are defining the touch area (matrix-structure). • The numbers of measuring points is defined by the numbers of X- and Y-lines. E.g. 8 x 6 = 48 or 18 x12 = 216 (depending on the controller and the design of the foil). • By interpolation a theoretical resolution of 1024 x 1024 is possible (10bit). • The sensitivity of the touch could be adjusted by software.

General advice when setup easyTouch Fixation of the easyTouch sensor on a table with adhesive tape (Tesa) Install the driver software first, then connect the hardware(check for latest driver updates on our website (support ->driver) Please note that the touch-cable is connected correctly Pay attention that the power supply is grounded, the “computer” runs by a battery or LAN-cable is connected to the computer Noise suppression could be done by Data Modul if the customer provides the complete system 16
Usage of a front foil When using a front foil the foil must always laminated on the touch or a glass to avoid air gaps and malfunction
