Performance

Input Method
Finger input

Accuracy*
Achievement of the listed specifications has been demonstrated in monitor integrations where the touch screen is mounted to monitor frame such that the spacing between the touch screen and monitor screen does not vary due to compression / expansion from touch forces or temperature changes.

Resolution
Reported touch coordinates are within 1.0% of true position (based on the diagonal dimension of the screen) within the precision area when linearized and used with MicroTouch™ EX II Series Touch Controllers.

Linearization
Factory linearization values are stored in the attached controller, represented in a 2D bar code, or in the touch screen NOVRAM when present.

Optics

Light Transmission**
91.5% light transmission (+1.5%)

Surface Finish
ClearTek II hard coat with optimal anti-glare properties. Scratch resistant top coat provides smooth, easy glide touch surface.

Mechanical

Minimum Contact Requirement
3ms for finger input with EX II series controller

Liquid Resistance
Liquids on screen do not impede touch screen performance

Operating Temperature
-15°C to 70°C for the touch screen

Storage Temperature
Always store the touch screen in its original shipping container between -50°C and 85°C (up to 90% RH from 0°C to +35°C). Never store touch screens in an environment where condensation may form.

Humidity
Up to 90% RH from 0°C to +35°C, non condensing

* Achievement of the listed specifications has been demonstrated in monitor integrations where the touch screen is mounted to monitor frame such that the spacing between the touch screen and monitor screen does not vary due to compression / expansion from touch forces or temperature changes.
