Rugged Solution for Impact Strength and User Safety
The 3M MicroTouch System SCT7650EX is a rugged version
of 3M's industry-leading surface capacitive system, the 3M
MicroTouch System SCT3250EX, which is created by laminating
4mm backer glass with optically-clear adhesive to a 3M MicroTouch
Sensor SCT7650. This robust laminated sensor, for applications
ranging from 10 to 32 inches, is specifically designed to withstand
heavy abuse in vandal-prone environments while providing excellent
light transmission.
™

™

™

™

This sensor's optimized design offers 86.5% light transmission
for brighter, crisper display images (compared to 81% for typical
rugged surface capacitive sensors), while providing superior impact
resistance by exceeding the UL 60950-1 certification (500 gram
steel ball dropped from 1.3 meter height). In the event of a sensor
breaking by extraordinary impact, the laminated construction is
designed to help protect the user from glass shards by holding the
multi-layered sensor together.
The systems' sophisticated 3M MicroTouch Controller EX provides
superior touch speed performance and industry-leading reliability.
This controller is well known for its < 5.4 milliseconds response time
and "intentional touch" capability, where false touches don't register
if a user's finger hovers over the screen or from inadvertent screen
contact with jewelry, clothing or other personal items.

™

With the widest operating- and storage-temperature range available,
NEMA 4 / IP 66 sealing, and superior performance in the presence
of surface contaminants and debris, the 3M MicroTouch System
