SAW Touch Screens

Dong Guan CJTouch Electronic Co.,Ltd is one of the leading saw touch screens manufacturers and suppliers and also a productive factory, we are always at your service.SAW Touch Screens A SAW touchscreen consists of a clear glass panel, transducers, reflection strips and cables. The transducers, cables and the reflection stripes are located on the front surface. The SAW controller sends electrical signals to transmitting transducers of both the X and Y axes. The transducers convert these electrical signals from the controller into ultrasonic waves which are then reflected by the reflector arrays and sent across the front, rear and side surfaces. These waves are then reflected back to the receiving transducers by another set of reflector array on each opposite side of the surface. The receiving transducers will convert the waves into electrical signals and feed them back to the controller. When the screen is touched, the finger absorbs a portion of the wave passing across the surface of the panel. The resulted change in ultrasonic wave frequency will be detected and a coordinate is calculated. This process happens independently for both the X and Y axes. Features: High clarity and resolution Drift-free operation Free of maintenance Durable and scratch-resistant Sizes ranging from 8” to 32” Sealable, anti-vandal, anti-glare optional Do not get affected by external electric noise Applications: Gaming/Amusement machines Automation Medical equipment Automated cash dispenser Financial Field More information of SAW Touch ScreenWorking principleCJTouch Surface Acoustic Wave SpecificationsTechnologySurface Acoustic Wave(SAW)Sizes8” to 32” (extending)Resolution4096 x 4096 ,Z-axis 256MaterialPure glass(Vandal-proof ,Anti-glare,Dustproof ,waterproof can optional)Transducer positionGlass bevel angle, up surface 0.5mmAccuracy<2mmLight Transmission>92% /ASTMTouch Force30g-80gDurabilityScratch-free; More than 50,000,000 touches in one location without failure.Surface HardnessMohs' 7Multi-touchOptional , software supportOperating Temp.-10°C to +60°CStorage Temp.-20°C to +70°CHumidity10%-90% RH / 40°C,Altitude3800mPartsConnect cable,Double-sided adhesive, dustproof stripCertificatesCE, FCC, RoHSController technical specificationController  Model NumberCCA-URL01-DM/CCA-URL01-ELOInterfaceUSB，RS232 can optionalSize(PCB)85mm×215;55mm×215;10mmWorking voltage12V×177;1V & 5V×177;0.5V optionalWorking Current80mAMaximum Current100mAResponse time×8804;12msOperating temperature0-65×8451;Operating humidity10%-90%RH.Storage temperature-20×8451;-70×8451;MTBF> 500,000 hoursCertificatesCE, FCC, RoHSOperate systemWinXP / Win7 /WinXPE / WinCE / Linux / AndroidLIST OF Standard SAW Touch PanelSizeRatioModelActive AreaViewable areaGlass DimensionOut LineCable LengthWeight8.0"4:3CTB080C-4F168x126172x130192x151195x1533000.318.4"4:3CTB084C-4F172x130176x134197x156200x1583000.3310"4:3CTB100C-4F-FFT203x152207x156229x179232x1813000.4310.1"16:9CTB101C-4KS225x127229x131251x153254x1553000.4110.2"16:9CTB102C-4K221x131225x135249x159252x1613000.4210.4"4:3CTB104C-4F213x160217x164239x187242x1893000.4711.6"16:9CTB116C-4K256x144258x146274x164277x1664500.4812.1"4:3CTB121C-4F247x185251x189273x212276x2144500.6112.1"16:9CTB121C-4K265x168272x175311x214314x2164500.7013.3"16:9CTB133C-4K-KR1286x179289x182316x209319x2114500.6914"16:10CTB141C-4K-GLX309x174313x178333x198336x2005000.6914.1"16:10CTB141C-4K-AVA304x190307x193322x214325x2164500.7215"4:3CTB151C-4F306x230310x234338x263341x2656000.9315.6"16:9CTB156C-4K347x197351x201381x231384x2336000.9217"5:4CTB170C-4F342x272344x276371x304374x3066001.1717"16:10CTB170C-4K-ZDD372x234380x242435x285438x2876001.2817.3"16:9CTB173C-4K382x215386x219412x245415x2476001.0518.516:9CTB185C-4K410x231413x234439x263442x2656001.2019"5:4CTB190C-4F382x305386x309417x341420x3436001.4619"16:9CTB190N-4K414x262417x265444x294447x2966001.3519.5"16:9CTB195C-4K435x240439x244475x278478x2806001.3620"16:9CTB200C-4K445x251449x256477x284480x2866001.4020.1"4:3CTB201N-4F410x308412x310442x340445x3426001.5421"4:3CTB210C-4F423x316434x328469x363472x3656001.7421.3"4:3CTB213C-4F432x324436x328470x361473x3636001.7421.5"16:9CTB215C-4K477x268480x271511x306514x3086001.6121.8"4:3CTB218C-4F-BX443x334445x336480x374483x3766001.8422"16:10CTB220C-4K476x297480x302511x338514x3406001.7723"16:9CTB230C-4K510x287514x291549x326552x3286001.8323.6"16:9CTB236C-4K525x297529x301559x331562x3336001.8924"16:9CTB240C-4K-VB531x299535x303570x339573x3416001.9724"16:10CTB240C-4K520x326523x329558x366561x3686002.0826"16:9CTB-F260C-4K580x328585x333617x365620x3676002.2927"16:9CTB-F270C-4K597x336601x340627x365630x3676002.3330"16:10CTB300C-4K640x400648x408680x440684x4446003.0332"16:9CTB-F320C-4K702x397710x405746x442749x4446003.34
