Gehäuserand

Gehäuserand is a term used in German engineering to refer to the boundary or outer edge of a device housing (Gehäuse). It denotes the external envelope that defines the outer dimensions and interfaces of an enclosure. In technical drawings, the Gehäuserand serves as a reference for tolerances, mating parts, and assembly features. Although not a formal standard term, it is commonly used in industry to indicate the limit of the housing that bears on or interacts with other components such as lids, panels, gaskets, or mounting brackets.

Typical features associated with the Gehäuserand include outer faces, flanges, mounting holes located on the edge, chamfers or radii at corners, and gasket lands. The design of the Gehäuserand affects manufacturability and function: material choice and wall thickness around the edge, surface finish requirements, sealing performance, and heat dissipation paths all revolve around this boundary. Accurate specification of the Gehäuserand helps ensure proper fit, sealing, and protection against dust, moisture, or mechanical ingress.

Terminology varies by company and field; some writers may use Gehäusekante or enclosure edge to express the same idea. See also Gehäuse, Toleranzen, Oberflächenfinish.
