The 3M SCT7650EX system is a rugged version of 3M’s industry-leading surface capacitive system. 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 a 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 EX controller provides superior touch speed performance and industry-leading reliability. This controller is well known for its <5.4 millisecond 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.
The SCT7650EX requires a cable to drive the touch sensor.
