WHAT ARE SAW TOUCH SCREENS?
Surface Acoustic Wave (SAW) technology is one of the most advanced types of touch screen solutions available in the touch screen market. SAW resistive touch screen technology uses ultrasonic waves that pass over the surface of the touchscreen panel. When the panel is touched, a portion of the wave is absorbed. This change in the waves then registers the position of the touch event and sends this information to the controller for processing. The controller then sends electrical signals to the transmitting transducer, which converts the signal into ultrasonicwaves.
Controller Information
Each SAW kit includes a sensor and a matching combination controller board for use with either a RS232 or USB cable. This controller board provides the optimal performance for your sensor. It offers superior touch sensitivity, accuracy, and user- friendly operation. A D Metro surface acoustic wave touchscreens are best used with the inbox plug and play driver for Windows 7 or 8. For other OS, the use of Touch Kit software utilities and driver are recommended to maximize the potential of the sensor’s capability. The software allows you to perform a calibration, test your touch device’s functionality in Draw Test, modify options for edge compensation, and more.
Typical Applications:
• Gaming machine
• Indoor or outdoor Kiosk
• ATM
• Industrial control
• Gas pump
• In-vehicle and transportation
• Medical equipment
