Our industrial touch screens use resistive touch sensors (discussed here), which are well suited for harsh industrial environments. The outer layer of these sensors is made of a polyester sheet that is coated with an acrylic “hard-coat” film for added scratch prevention. As a result, our touch screen sensors have a hard-wearing surface that is suitable for most environments.
The RoHS directive is a set of European Union regulations that relates to restriction of hazardous materials in electronic and electrical equipment. This directive came into force in 2006 and covers a wide range of electrical and electronic products.
Like most electronics vendors, we at Hope Industrial have worked with our suppliers over the years to ensure that our products are RoHS compliant (as detailed here).
For many years, our line of Industrial KVM Extenders has been a critical part of our product line-up, allowing our customers to forego the expense and hassle of a fully ruggedized PC by extending keyboard, video, and touch screen signals from a ruggedized industrial workstation back to a standard PC or server located in a clean, safe IT closet.
Depending on the environment, there are different requirements for user interfaces and how people need to interact. Recognizing this, Elo added a few features to their drivers that provide some advanced functionality to enhance usability for very specific purposes.
More and more often, our industrial touch screen customers are taking advantage of the open source Linux operating system, Ubuntu. Ubuntu has evolved into a versatile, easy-to-configure environment with a large community following and massive support from the company Canonical. We have seen a steady increase in calls from customers leveraging Linux in industrial environments, and in recent years Ubuntu has been leading the charge. In addition to the standard Elo-provided Linux driver, Ubuntu users now have a very simple touch screen driver solution that requires no new software.

A common problem for any fully enclosed NEMA 4/4X, IP65/66 rated display is exactly how to get the cables in and out of the enclosure while maintaining a water-tight seal. This problem has been approached in a variety of ways by equipment suppliers, but usually the solution involves either conduit, some sort of compression gland, or watertight external connectors with custom mated cables.
