HCT121A4B016-RS232 is a standard 12.1 inch 4-wire resistive touch panel constructed from ITO on 0.188 mm film substrate, providing an extremely robust structure with excellent optical properties. This touch sensor is typically optically bonded to a 1.80 mm thick strengthened cover lens with surface hardness 3H and light transmission over 78%. The flex cable is assembled with a 2.54mm 4Pin socket, can be converted to USB 2.0 interface with EETI USB controller board. This resistive is compatible with a 12 inch TFT LCD 800x600 or 1024x768 resolution.
