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

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.

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.

Advantage of the “stamp” concept:+ Atmel touch chip is an BGA (ball grid array with a pitch of 0,65mm -> difficult to solder
Stamp is easy to solder on the PCB board of the customer+ Stamp is logistic wise easy to handle (no MOQ)+ Flexible integration of the stamp on customers PCB

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
