Resistive Touch Screen Solutions

8-Wire Touch Screens

Request A Quote

The 8-wire Resistive touch screen is the preferred solution for applications where accuracy is crucial and recalibration is unacceptable. Similar in construction to 4-wire resistive technology, each edge provides one more sensing line as a stable voltage gradient for the touch screen controller. The additional 4 lines enable the controller to automatically correct for drift resulting from harsh environments and extended use.
