Claim:
A switchgear cabinet or rack comprising a mounting unit the front of which has vertical mounting profiles that laterally delimit an installation space for installed user-side units, the front of said profiles being provided with flat fixing sections for attaching laterally projecting mounting sections of the installed units, and comprising components of a detection device for determining the presence of an installed unit in an installation position of the installation space, wherein the components of the detection device have a vertical detector strip that is attached to a mounting profile and contains detector elements and code carriers that are provided on the installed units, wherein said mounting profile has a cavity that is at least partially adapted to the cross-section of the detector strip, is open at the front and is located laterally outside the neighboring fixing section, an abutment section that is set back in relation to the plane of the fixing section at least by the cross-section depth of the detector strip and an inner boundary wall that delimits the cavity on the side facing the installation space, wherein said detector strip lies with its front on the plane of the fixing section or is set back in relation thereto by a maximum of 10 mm and the relevant code carrier is arranged in front of said detector strip and is attached to a support section of a retaining element overlapping said detector strip which is attached to the neighboring mounting section of the associated installed unit via a connecting section.
