3M™ MicroTouch™ System SCT3250CX
The Clear Solution for Small Touch Applications (5.7" to 12.1" display sizes)
Developed specifically to meet the optical and durability needs of small display applications, the price competitive 3M MicroTouch System SCT3250CX provides superior surface durability and typically 11.5% higher optical transmission than certain 5-wire resistive solutions for device manufacturers requiring more reliable and brighter touch displays.
Based on the 3M™ MicroTouch™ Electronics CX, the system's HID-USB controller offers a reduced component count and slim 0.8" x 1.9" board, making it up to 54% smaller and requiring up to 25% less power compared to certain 5-wire resistive solutions.
All-Glass Solution with 3M ClearTek Hard Coat
- Up to 11.5% better light transmission than typical resistive solutions offers superior display performance
- Superior surface durability is designed to maintain optical and functional performance over the life of the product
- All-glass sensor is unaffected by spacer dots or damaged films to provide increased reliability and accuracy
3M MicroTouch Electronics CX
- Small form factor for compact devices with limited space
- Single IC solution minimizes component count and achieves higher MTBF
- Up to 25% less power consumption for power-constrained applications
Scratch-resistant Top Coat
