The Clear Solution for Demanding Touch Applications
3M Touch Systems has more than 25 years of surface capacitive
technology expertise and specifically designed the 3M MicroTouch
System SCT3250EX to meet the performance requirements of display
applications ranging from 5.7 to 32 inches. As an all-glass design, the
SCT3250EX touch system offers light transmission up to 11.5% better
than typical resistive sensors and 3.5% better than typical surface
capacitive sensors (based on published specifications).
™

™

With the combination of the 3M ClearTek proprietary hard coat and a
scratch-resistant top coat, the 3M MicroTouch Sensor SCT3250 offers
superior surface durability compared to typical resistive and surface
capacitive solutions. This surface durability feature helps the SCT3250
touch sensor support heavy-use applications while maintaining its
functional, optical and aesthetic characteristics.

In addition to the superior 3M MicroTouch SCT3250 touch sensor
design, the 3M MicroTouch Controller EX with its dedicated custom
ASIC sets the performance standard for capacitive sensing electronics
and offers industry-leading ESD protection (based on published
specifications). The EX controller's proprietary firmware and patented
algorithms dynamically adapt to changes in the application’s environment
to help maintain the initial video alignment of the display for the life of the
product. And, due to the dedicated ASIC, the SCT3250EX touch system
has a "minimum touch duration" that is 50% faster than typical surface
acoustic wave and surface capacitive solutions (based on published
specifications).
