3M™ MicroTouch™ System SCT7650EX

Rugged Solution for Impact Strength and User Safety.

The 3M MicroTouch System SCT7650EX is a surface capacitive touch system - an ideal solution for ruggedized self-service kiosks and ATM applications - environments where impact strength, shatter resistance, brighter displays, and superior surface wear are a requirement.

As 3M's most rugged touch product, its construction combines a 3M surface capacitive touch sensor with 4mm backer glass with optically-clear lamination. This glass-on-glass laminated vandal resistant construction makes it an ideal touch solution for unsupervised, vandal-prone environments.

Available sizes-10.4" to 19"
