B&R says that using one of its touch screens enables a new form of intuitive operator guidance
Typical operating functions are now incorporated directly into the glass of these screen panels from B&R, eliminating the need for hardware switches and leaving no chance for dirt and grime to collect or enter a device. Unsurprisingly, the company cites environments with the strictest hygienic requirements as prime users of the technology.
On request B&R can provide all HMI variants with a projected capacitive touch screen that has corresponding finger guides. The guides can be any shape and size, enabling the optimal integration of all types of sliders and dials in the HMI application. This, it says, opens up the entire screen surface for displaying content. B&R's patented tactile finger guides allow ‘eyes-off’ operation, and users can adjust the settings without ever taking their attention off the machine.
Ergonomic finger guides
The ergonomic finger guides are approximately one millimetre deep and can can be specified with either a matt or clear finish with integrated keys and rotary switches that never wear out. The panels are available in sizes from as small as 5" to as large as 24" as either a display unit or a panel PC.
B&R panels with finger guides are said to be well suited for the food and beverage, pharmaceutical and medical technology industries. In addition to the easy-to-clean touch screen, the panels are also available with a joint-free stainless steel housing that offers IP69K protection. Hygienic-design panels are constructed from highly resistant materials such as smooth stainless steel, high-quality polyester overlays and special sealants.
