What do switch, control, and server racks have in common? They are subject to stringent requirements because they must provide the best possible protection for the electronics and other, sometimes highly sensitive, devices inside the rack. It is imperative to prevent the infiltration of dust, dirt, and water. Moreover, it is critical to ascertain the safety of the contents and restrict unauthorized persons from gaining access. EMKA, the leading company in the global market, showcases how this can be achieved through its innovative locking systems.
Seals on doors exceeding a height of 2,000 mm often display inadequate air tightness in the corners, rendering the doors ineffective in deterring unauthorized entry. Multiple interlocking systems with cams inside the seal are the method of choice in such cases, as they enable optimum distribution of the closing forces due to the numerous locking points. Three to seven locking points can be incorporated with this solution – and even more for particularly large doors. One notable benefit is the high level of operating convenience thanks to the synchronised closing process.
Only a single operating element needs to be actuated to lock the door of an enclosure or the lid of an underfloor container at several points, for example. A continuous rod connects the individual locking points with each other and thus prevents delays or transmission errors during the locking process. At the same time, the three, five, seven or more cams driven in this way move, depending on the application.
The result is significant time savings during the opening and closing process. Locking expert EMKA offers this system not only with an extensive selection of operating elements but also with a compression unit and optional corner drive. By using the multiple interlocking system with cams and additional compression, the tightness of the door and ease of use can be further increased. All locking points with turn-and-tighten function pull the door securely and smoothly into the surrounding door seal. When the door is closed at a 90° angle, there is a combined turning and lifting motion accompanied by an additional 4 mm compression.
