AccuTouch Touchscreen Specifications

	AccuTouch Touchscreen Specifications
Mechanical
Construction		Top: Polyester with outside hard-surface coating with clear or antiglare finish.
		Inside: Transparent conductive coating.
		Bottom: Glass substrate with uniform resistive coating. Top and bottom layers
		separated by patented separator dots.
Positional Accuracy		Standard deviation of error is less than 0.080 in. (2.03 mm). This equates to less
		than ±1%.
