TOUCH Infra Red
Infrared (IR) touch screens consist of a touch frame which is installed in front of the display. The frame is intergrated with a printed circuit board which contains a line of IR-LEDs and photo transistors hidden behind the bezel of the touch frame. The bezel shields the parts from the operation environment while allowing the IR beams to pass through.
When touch is applied, the screen enters the gird by a stylus which can interrupt the IR light beams. Photo transistors from X & Y axes detect the IR light beams which have been interrupted and transmit exact signals that identify the X & Y axes coordinates to the host.
IR touchscreens are claimed to have the lowest cost of ownership in industrial and other demanding environments.
Typical advantages of IR touch:
- Fast response and interaction
- High reliability because it is wear-resistant
- Use with finger, gloves and other stylus
- Low profile available
- Available with anti-impact and vandal proof glass
- Large size available
- Drift free and high transparancy
- Mostly standard IP 65 sealed
- Multi touch available
- Easy installation and easy maintaince

For all our touchscreens complete interface kits are available. It can be a controller as a component or a RS232/USB interface with cable set and software driver.
Only for our range of IR touchsceens, the controller board can be integrated in the touchframe, saving space, money and assembly efforts.
