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.
Applications
Food processing
Industrial automation
Bank / ATM / Kiosks
Medical equipment
In-vehicle and transportation
Point-of-sale (POS) terminals
