Abstract

An industrial control device includes a display, a body, a first sensor, and a controller. The body includes a facia wall, an inner shroud, and an outer shroud. The facia wall includes a window that is a transparent material aligned to permit the display to be viewed through the window. The inner shroud extends rearward from a rear side of the facia wall. The outer shroud is disposed about the inner shroud and extends rearward from the rear side of the facia wall and is spaced apart from the inner shroud to define a cavity. A seal member is within the cavity forms a seal with a facia plate disposed about the inner shroud. The first sensor detects contact with a front surface of the facia wall. The controller is coupled to an output of the first sensor. The controller is coupled to the display and controls the display.
