The resistive product line has been structured to easily identify which sensors should be used with which controllers. Back to top 3. All resistive products will be affected by ultra-violet exposure. In the normal course of a resistive touchscreen s life it will not typically be exposed to enough UV light to affect it. UV rays are typically filtered by the glass in windows which greatly reduces the amount of UV a sensor is exposed to, even if it s in a sunny location.
Outdoor applications are another matter.
The base polyester material which topsheets are constructed is affected by direct and prolonged exposure to UV rays. With prolonged exposure, the topsheets will yellow and will likely become brittle. For this reason, resistive technology should not be promoted in applications which will experience direct and prolonged exposure to the sun. Back to top 4. Light transmissivity is measured at 550nm.
