The 12 (12.1) inch industrial Surface Acoustic Wave (SAW) touch screen LED open frame monitor comes in two model types that are a 4:3 aspect ratio from Caltron Industries.  The first model is the LBT-1212OTEAS, which has an RS232 serial touch interface.  The second model is the LBT-1212OTEASU, which indicates that the unit comes with a USB touch interface.  Under certain circumstances, the unit can have both a serial and USB touch interface, but only one can be used at any given time, even if both touch interfaces are provided.

What good is an industrial 12.1” open frame touch screen for my application?  A 12 inch touch screen monitor is highly popular and widely used in many applications like Automatic Teller Machines (ATMs) and any location that might want a SAW touch screen monitor.  Is the LBT-1212OTEAS reliable?  Like all of Caltron’s other open frame touch screen monitors, not only is the unit comprised of all industrial grade components, but the parts are all housed in a sturdy chassis that is milled from a CNC machine. 

An LED backlit open frame touch screen monitor like the LBT-1212OTEAS, can be used in both indoor or outdoor applications.  With a brighter rated screen than a typical CCFL backlit monitor, this SAW touch screen monitor is great for areas with higher than typical ambient lighting.  The type of touch screen monitor can be used in various applications that include, photo booths, Kiosks, control panels, to just about anything that requires an open frame touch screen to be uniquely designed into a larger enclosure.
