The new control unit series DUX-Basic fit into a mounting diameter of 22.3 mm. The velvet mat, noble metallic surface of the front bezels enhances the appearance of each control panel. The units distinguish by their harmonic design and by the manifold possibilities of colour combinations. That allows each user to design the control panel of his machine/plant individually. The switching positions of key and selector switches are indicated on the front bezels, thus, make external position indicators superfluous. DUX-Basic means a modular combination system standing every challenge and its polymorphism making the control surface of each machine/plant unique.
