Rugged Solution for Impact Strength and User Safety

3M™ MicroTouch™ System SCT7650EX

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 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

SCT7650EX is ideal for unattended kiosks, outdoor ATMs, and high-

use, environmentally-demanding applications, and provides ﬂexibility

for system designers requiring a robust touch system solution.
