Abstract: A magneto-mechanical sensor can be use for paramagnetic gas analysis, in which a test piece has a conductor loop is rotatably held by at least one suspension wire. In order to be able to produce the conductor loop, which is to be electrically connected to the at least one suspension wire, with little manual effort and use a small-sized, light-weight sensor, portions of the conductor loop are applied to the surface of the test piece using a metallization process.

Abstract: A passage control device for persons is provided, including at least one housing, at least one blocking element held so as to be movable relative to the housing, a drive, arranged substantially in the housing, for blocking and releasing and/or moving the at least one blocking element, and a control unit for the drive, which acts in combination with a control element for identifying an authorization, and which controls the drive in accordance with the authorization, in order either to block or release, and/or to move, the blocking element. The housing is constructed having a frame element formed substantially of a plastic or a plastic composite material, having a support structure, arranged inside the frame element, for the blocking element and the drive, and having a rear and a front cover plate, which are formed substantially of a plastic or a plastic composite material and fastened to the frame element.
