Infrared-Touchscreens
Operating principle
The infrared-touchscreen is surrounded by a frame which contains IR-light sources, the detectors are on the opposite side. Thereby, an invisible curtain is projected in vertical and horizontal direction. As soon as the raster is interrupted by an object, the position can be defined.

In this technology, all sizes from 12" to 80" are generally possible
The carrier glass can be chosen freely and can be delivered in breakproof acryl glass for the food industry or for a sensitive environment.
