15" vandalproof SAW touch screen
The Surface Acoustic Wave (SAW) technology is one of the most advanced touch screen types. The technology is based on two transducers (transmitting and receiving) placed for the both of X and Y axis on the touch panel. The other important element of SAW is placed on the glass, called reflector. The controller sends electrical signal to the transmitting transducer, and transducer converts the signal into ultrasonic waves and emits to reflectors that are lined up along the edge of the panel. After reflectors refract waves to the receiving transducers, the receiving transducer converts the waves into an electrical signal and sends back to the controller. When a finger touches the screen, the waves are absorbed, causing a touch event to be detected at that point.
Compared to Resistive and Capacitive technologies, SAW technology provides superior image clarity, resolution, and higher light transmission. Because the panel is all glass, there are no layers that can be worn, giving this technology the highest durability factor and also the highest clarity. The Surface Acoustic Wave technology is recommended for ATMs, Amusement Parks, Banking and Financial Applications, public information kiosks, computer based training, or other high traffic indoor environments. Surface wave touch screen panels are the most advanced of the four types. SAW offers excellent clarity and durability and allows gloved hand use.
Features:
This type of touch screen uses 6mm tempered glass, which provide excellent impact-proof ,vandal-proof performance,
and could be used in public environments where vandalism is a concern or in unsupervised or industrial environments.
Even if a touchscreen is broken, the fragments are safe with no sharp edges
With tempered, 6mm thickness glass, these touchscreens can withstand the impact of a 1000g steel ball, dropped from a height of 1 meter, in accordance with Trial Standard Number GB/T9963-1998..
With a tempered, 4mm-thickness-glass, these touchscreens can withstand the impact of a 500g steel ball, dropped from a height of 1.3 meters, in accordance with Trial Standard Number 60950©IEC 1999
