AccuTouch resistive Touchscreen Specifications

AccuTouch (resistive) Touchscreen Specifications

Positional Accuracy	Standard deviation of error is less than 0.080 in. (2.03 mm).
	Equates to less than ±1%.
Touchpoint Density		More than 100,000 touchpoints/in2(15,500 touchpoints/cm2)
Touch Activation Force		Typical less than 3 ounces(85 grams)
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.
