iTouch Surface Acoustic Wave Touch Technology

Screen Size

7.0" to 32"

Construction

Glass panel with transducers attached to the back surface of the glass. Glass has a black painted border on the front.

Expected Life Performance

No known wear-out mechanism, as there are no layers, coatings, or moving parts. Surface acoustic wave (SAW) technology has been operationally tested to more than 50 million touches in one location without failure, using a stylus similar to a finger.

Sealing

iTouch Plus touchscreen has been successfully integrated by integrators to meet NEMA 3/3R/5/12/12K/13, IPX1 standards.

Surface Durability

Surface durability is that of glass, Mohs' hardness rating of 6.5.

• Operating temperature: -20°C to 50°C
• Storage temperature: -40°C to 71°C
• Operating relative humidity: 90% RH at 40°C, noncondensing
• Operating altitude: 10,000 feet (3,048 meters)
• Storage/transport altitude: 50,000 feet (15,240 meters)
• Chemical resistance: The active area of the touchscreen is resistant to all chemicals that do not affect glass, such as:
  • Acetone
  • Toluene
  • Methyl ethyl ketone
  • Isopropyl alcohol
  • Methyl alcohol
  • Ethyl acetate
  • Ammonia-based glass cleaners
  • Gasoline
  • Kerosene
  • Vinegar

Positional Accuracy

Less than ± 2.5mm and typically much better when touchscreen and controller are calibrated to a display image.

Resolution

6.19 points per mm typical.

Touch Activation Force

2 to 3 ounces (55 to 85 grams) typical.

Controller

Board: Serial (RS232) or USB

Light Transmission

• Up to 92% per ASTM D1003

Certifications/Compliance

UL, cUL, TÜV, CE, FCC Class A, RoHS compliant

Two year limited warranty on touchscreen (when sold as components)
