Job Details

What cannot be overstated is the open frame’s lack of enclosure. This gives the integrator the freedom to create their custom-designed enclosure. Some obvious examples which can be seen every day are cabinets with embedded touch monitors, recessed walls, or tables used for digital signage applications including store front displays, photo booths, arcade games, and even advertising billboards.

VESA Standards For Panel PC Mount

Whether one is considering the traditional closed frame or industrial open frame display to be their optimal solution for their application; one must also take into account on how they will manage to mount their display. Most closed and open frame industrial panels provide a panel mount. However, there may be instances in which the panel display needs to be mounted from the rear. This type of mounting interface for a panel PC is usually not some arbitrary design. If that is the case, then mounting the panel display could very well be the most difficult part in designing your application. The Video Electronics Standards Association, better known as VESA, provides technical standards for panel mounts which is usually referred to as a VESA mount. This standard is defined by 7 sizes each with more than one variant. By having such standard, it allows the integrator to design their enclosure to adhere to a particular VESA mount to help simplify the process.

For many of today’s demand on digital signage applications, a closed frame industrial panel PC might just be the answer. However, it is important that the touch panel is reliable and durable even in high touch operating environments, as well as rugged enough to endure harsh conditions. For other integrators, the option of having an open frame solution can minimize workload and eliminate unnecessary disassembly, plus it can also ease the process of designing their enclosure to integrate with the panel. Furthermore, the panel mount minimizes the frustration of having to design the enclosure, knowing there is a set of VESA standard mount to take into consideration. By taking advantage of any of these 3 possibilities, you can customize an optimal design and solution for your touch panel application.

USB charger

A power adapter that generates the 5 volt DC standard required by USB. The amperage varies, typically from .07A to 2.4A. The charger plugs into an AC outlet, and a USB cable plugs into the charger. USB ports on computers have an upper limit of 500 milliamps; however, USB chargers that come with cellphones and other devices handle one or more amps. The devices sense when they are connected to a computer versus the charger and regulate their current draw.
