Machines and systems for chemical, foodstuffs and pharmaceuticals industry are subject to particularly demanding requirements for hygiene. In particular, equipment used in such machines, must avoid any gaps, in which dirt, bacteria or germs could settle. To avoid this, a hygiene-compliant display and control device having a front plate is proposed, having a peripheral groove, which is open on the outer peripheral surface of the front plate, on the outer edge of the front plate, and a sealing element fitted in the peripheral groove. The outer peripheral surface of the sealing element is arranged flush with the outer peripheral surface of the front plate, and a number of clamping arrangements with a pressing element are provided on the display and control device distributed around the periphery. One axial end of the pressing element engages with a fixing frame, which rests on the mounting plate, or with the mounting plate.
