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 layers electrodes. The controller can detected the touch point by the position on the X and Y-axis. 4-wire General specificationAvailable Size:3"-11"Touch Activation Force:20g 150gThickness:ITO Film:0.188mmOperating Voltage:Less than 12VOperating Current:DC50mA/5VX,Y Resistance:according to the sizeInsulation Resistance:≥20MΩ/25V(DC)Linearity:≤1.5%Response Time:<10msTransparency:≥75%Surface Disposal:Anti Glare, GlareOperating Temperature:-20°C +70°C,≤70%RH,noncondensingStorage Temperature:-30°C +80°C,≤90%RH,noncondensingHumidity:<95%Surface Hardness:3HPen Hitting Life:1millions timesPen Sliding Durability:100thousand times We are manufactory, we are the source, so our price is very competitive on the market.
