IntelliTouch Surface Acoustic Wave Technology

Table B-3IntelliTouch Specifications

Input Method	Finger or gloved hand (cloth, leather or rubber) activation.
Mechanical Positional Accuracy	Standard deviation of error is less than 2.03 mm (0.080 in).
	Equates to less than ±1%.
Touchpoint Density	More than 15,500 touchpoints/cm2 (100,000 touchpoints/in2).
Touch Activation Force	Typically less than 85 grams (3 ounces).
Surface Durability	Surface durability is that of glass, Mohs’ hardness rating of 7.
Expected Life Performance	No known wear-out mechanism, as there are no layers,
	coatings, or moving parts. IntelliTouch technology has been
	operationally tested to more than 50 million touches in one
	location without failure, using a stylus similar to a finger
Sealing	Unit is sealed to protect against splashed liquids, dirt, and dust.
Optical Light Transmission (per ASTM D1003)	up to 92%
Visual Resolution	All measurements made using USAF 1951 Resolution Chart,
	under 30X magnification, with test unit located approximately
	38 mm (1.5 in) from surface of resolution chart
	Clear surface: Excellent, with no noticeable degradation.
	Antiglare surface: 6:1 minimum.
Gloss (per ASTM D2457 using a 60- degree gloss meter)	Antiglare surface: curved or flat: 95 ± 15 gloss units or 65 ± 15
	gloss units; Clear surface: N/A
Environmental 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
Electrostatic Protection (per EN 61 000-4-2, 1995)	Meets Level 4 (15 kV air/8 kV contact discharges).
