The protective housing (1) has a back wall (2) with a cable inlet (14). It also has a window wall (3) for optical devices (5), with an optical axis (AO). The housing (1) has, to spatially align the optical axis (AO), a fastening device (9) with hinge members (G1,G2,G3), pivot axes (A1,A2,A3) and a holder (10). The latter (10) has a rotary socket (11) with a first pivot axis (A1) and a locating surface (FA) for attaching to a fastening surface (F). The pivot axis of the rotary socket (11) is perpendicular to the locating surface (FA). The fastening device (9) has at least one further pivot axis (A2,A3) perpendicular to the first axis (A1). Three hinge members (G1,2,3) are arranged between the back wall (2) and the holder (10). The first hinge member (G1) is connected to the holder (10) via the rotary socket (11) and the third hinge member ((G3) is connected to the back wall (2). Two further pivot axes (A2,A3) are arranged between the hinge members (G1/G2 and G2/G3). When the housing (1) is assembled one of the further axes (A2,A3) is horizontal and the other is perpendicular. The hinge members surround a cable guide channel which leads to the cable inlet (14) in the back wall (2). |
