TOUCH TECHNOLOGIES: SURFACE ACOUSTIC WAVE (SAW)

TOUCH TECHNOLOGIES: SURFACE ACOUSTIC WAVE (SAW)

SAW technology works by using ultrasonic waves to detect touch events. When the panel is touched, a portion of the wave is absorbed. Keetouch is the second worldwide company that uses evaporation method for making marks on touch screens.

DURABLE GLASS
DURABLE GLASS

SAW screens use anti-vandal, impact-resistant 4 mm glass that is almost impossible to break unintentionally.

SAW touchscreen monitors have their front panel dust-proof. Optional models are available with water-proof front panel.

In places with constant temperature change additional protection required against humidity on components of certain electronic parts (controller, connectors) of the equipment.

In case of minor contamination, SAW screen needs to be cleaned with a wet wipe. In case of serious contamination that affects SAW reflector arrays, please contact technical support of Keetouch. Minor contaminants (dust, dirt, grease) on the glass surface will not damage the screen, when it’s dried out or removed, the screen will continue to function normally.

PERFECT FOR USE IN PUBLIC ENVIRONMENTS
PERFECT FOR USE IN PUBLIC ENVIRONMENTS
  • High throughput
  • SAW technology is the perfect choice for busy traffic indoor public environments as it can be used by a number of users daily and withstand thousands of touches daily having a very high throughput. The most popular spheres include HORECA, retail, and advertising.

  • High transparency
  • SAW screen has minimal impact on the clarity and brightness of the display image.

  • Long service life
  • SAW touch technology works on the surface of the panel. The glass is wear-resistant and highly durable, minor mechanical damage to the working surface (scratches, abrasions, scuffs) does not affect the operation of the SAW touch screen.

PERFECT FOR USE IN HARSH CONDITIONS
PERFECT FOR USE IN HARSH CONDITIONS
  • Wide operating temperature range
  • Engineered to function in any climate, including extremely cold/hot weather, excessive snowfalls, rain or dust. At low / high operating temperatures it is necessary maintain the heating / cooling of the equipment with a built-in touch screen.

  • The working surface of the screen does not oxidize or corrode
  • The working surface of the screen does not oxidize, corrode, or react with household chemicals which makes it suitable for chemical industry application.

  • Responds to a finger touch or special stylus for SAW screens
  • Typically, the software of devices for public use is designed to support one touch and involves step-by-step use. Optional double-touch makes gesture control possible.
