4 wire 5.6'' resistive touch screen 1 Features 4-Wire resistive touch screen is the preferred solution for low cost applications. It consists of a conductive bottom layer (ITO Glass or Film) and a conductive top layer (ITO Film). The two layers are suspended by many very small spacer dots.When a certain point is touched, the top layer contacts the bottom layer and a voltage charged by the controller is applied to the bottom layer's electrodes. The coordinate X axis of the touch point can be detected by measuring the voltage value thru the top ITO layer and the coordinate Y axis of the touch point can be detected in the same way by changing voltage input to the top layer's electrodes. 2 specifications SurfaceHardness3HOptical Clarity80%↑OperatingTemperature-10C 60CEnduranceTest strikesOver1millionOperatingVoltageDC5VResistance200Ω 900ΩLinearity1.5%FaceplateSurfaceAnti-glarecoating,glare coatingFilm Thickness0.175mm, 0.188mmGlass Thickness0.7mm, 1.1mm,1.8mmOperationPressure20 150gStorageTemperature-30 80MessageNoise5m sec 15m secOperatingCurrent5mA 25mAHumidity<95%IsolationResistance20MΩ↑ DC25VSealable againstdust ,water, oil , static3 advantages 1.Our products' insulation point is Φ0.03mm, this technology is advanced.2.Various choices of surface treatments available,anti-Newton,anti-glare,special chemical stenghen hard coating,anti-reflection.3.Capable of handing spacer dots diameter is less than 0.035mm.4.We have our own factories,so our price is competitive.5.The excellent sales service.4 application1 Light industrial 2 Home appliances 3 Portable sport devices4 Access control terminals 5 Portable medical devices5 pictures
