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 separator dots.

Cable and Connector

Cable typically exits from the left side, terminating in a five-position, 0.025 in (0.635 mm) square post receptacle.

Positional Accuracy

Standard deviation of error is less than 0.080 in (2.03 mm). Equates to less than ±1% error on most displays.

Touchpoint Density

More than 100,000 touchpoints/in² (15,500 touchpoints/cm²) for a 13-in touchscreen when used with controllers.

Touch Activation Force

Typically less than 4 ounces (113 grams).

Surface Durability

Meets Taber Abrasion Test (ASTM D 1044), CS-10F wheel, 500 g. Meets pencil hardness 3H per ASTM D 3363.

Expected Life Performance

AccuTouch technology has been operationally tested to greater than 35 million touches in one location without failure, using a stylus similar to a finger.

Sealing

Unit can be sealed to NEMA requirements. See AccuTouch Product Manual for details.
