Why the Competition Can’t Touch Us
Touchscreens that rely on other technologies—such as capacitive, infrared, and
four-wire resistive—simply can’t promise the reliability, stability, linearity, and
durability of AccuTouch touchscreens. Our patented five-wire design is a proven
technology that surpasses other designs.
Unbeatable Service and Support
We’re extremely serious about service. So we back up our AccuTouch product line,
before and after the sale, with:
| AccuTouch Five-Wire Resistive |
Capacitive | Infrared | Four-Wire Resistive | |
|---|---|---|---|---|
| Touchscreen Life | Tested to over 35 million touches. Constant flexing won’t degrade accuracy over time. | Specified to over 20 million touches. Coatings can wear. | Large number of photo diodes and photo transistors effect long-term reliability. | Typically fewer than 2 million touches. Constant flexing will degrade accuracy over time. |
| Touch | Any light touch activation—by finger, gloved hand, or stylus—with accurate response every time. | Touch response may vary due to user’s body size, ground path (user’s body is part of the completed circuit). | “False” touch can be caused by anything that breaks infrared beam (even dust or an insect). | Activated by finger, gloved hand, or stylus. |
| Touchpoint Density | High—100,000 touchpoints/in2 | Medium—13,000 touchpoints/in2 | Low—64 touchpoints/in2 | High—100,000 touchpoints/in2 |
| Calibration Stability | Stable, no-drift operation | Unstable—may require frequent recalibration due to changes in environment | Stable | Stable |
| Light Transmission | Up to 75% | Up to 85% | Up to 100% | Up to 75% |
| Scratch Resistance | Hard coated for scratch resistance. Deep scratches and abrasions will not degrade accuracy. | Although hard coated for scratch resistance, scratches and abrasions may degrade accuracy. | Not applicable. | Hard coated for scratch resistance. |
| Contaminant Resistance | Resists moisture, dirt, vinegar and ammonia-based food products and cleansers. | May be affected by vinegar and ammonia-based food products and cleansers. | May be affected by sunlight and dust. | Resists moisture, dirt, vinegar and ammonia-based food products and cleansers. |
| Gasket Sealing |
Sealable | Sealable—must be non-conductive material | Sealable—must have custom bezel | Sealable |
| Configuration Option | Flat, spherical, and cylindrical | Flat, spherical, and cylindrical | Flat only (parallax problems with spherical and cylindrical) | Flat and cylindrical |
