    21.5 inch Surface Acoustic Wave Touch Screen Overlay Touch Glass Kit with Controller and USB Cable

    CJTOUCH offers a complete line of Surface Acoustic Wave (SAW) touch screens kits. SAW offers an excellent alternative for many touch applications requiring an accurate light touch and excellent optical characteristics all in a very durable and reliable package.
    This glass sensor is ideal for indoor applications providing superior image clarity and sensor durability.
    Available in sizes from 8" to 23" diagonal CTB sizes also availableHighest Clarity, most durable touchscreen solution .All glass solution with no coatings to wear out .Gloved finger, finger or stylus activation4096 x 4096 resolution.Shielded connector.

    Compared to Resistive and Capacitive technologies, SAW technology provides superior image clarity, resolution, and higher light transmission. The panel is composed of durable glass and this augments the durability and clarity of the technology. SAW technology uses ultrasonic waves that pass over the surface of touchscreen panel. When the panel is touched, a portion of the wave is absorbed. This change in the ultrasonic waves registers the position of the touch event and sends this information to the controller for processing.
    In a controlled environment, SAW offers a very attractive, simple to implement, and cost effective solution.
