Capacitive touch system for compact devices from 3M

The SCT system integrates a MicroTouch Sensor SCT3250 and the newly-released MicroTouch Controller CX. With a reduced component count and slim 0.8” x 1.9” board, this USB-HID controller is up to 54 per cent smaller and requires up to 25 per cent less power compared to typical 5-wire resistive solutions, making it ideal for compact touch devices with limited board space and low power requirements.

“With superior surface durability and typically 11.5 per cent higher optical transmission than traditional 5-wire and 7-wire resistive touch solutions, our new all-glass SCT system presents compact device manufacturers with a more robust and reliable, yet competitively priced alternative,” said Paolo Pedrazzoli, Marketing Operations Manager, 3M Touch Systems.
