摘要： An opto-electronic transducer having a lens-type optical coupling wherein a lens within a lens carrier is arranged in the beam path immediately in front of the transducer. The lens carrier, together with the lens, are fixed to a fastening part by a fastening layer that is adjusted relative to the beam axis of the transducer. The fastening part is part of a common carrier for the transducer. The opto-electronic transducer and the lens carrier together with the lens are secured on the common carrier in such a spacial relationship relative to one another that the beam axis of the transducer is perpendicular to the surface formed by the fastening layer. The opto-electronic transducer of the invention is particularly suited for use as a light waveguide transmission or reception component or, alternatively, as an individual light source.

摘要： An electronic compass has a compass housing. An electronic magnetic field sensor is disposed in a fixed position relative to the compass housing. A magnet is rotatably mounted relative to the magnetic field sensor and independently aligned with a terrestrial magnetic field. The magnet has a magnetic field with a magnetic field direction and the electronic magnetic field sensor is located within a range of influence of the magnetic field. The electronic magnetic field sensor has a first magnetoresistor with a first fixed reference axis and an electric resistance of the first magnetoresistor is a function of a first angle of rotation between the fixed first reference axis and the direction of the magnetic field. The electronic magnetic field sensor defines a first differential bridge circuit and the first magnetoresistor is disposed in the first differential bridge circuit which during operation of the compass, supplies an output voltage dependent on the first angle of rotation. The first differential bridge circuit has a second magnetoresistor, and magnetizations of the first magnetoresistor and the second magnetoresistor are rotated relative to one another.

摘要： The contactless proximity switch detects one or more predefined spacing distances between a first part and a second part. The two parts are movably disposed relative to one another. A magnetic angle sensor is disposed in or on the first part and a driver magnet with a driving magnetic field is arranged in or on the second part. When the two parts are at the predefined spacing between then the driving magnetic field produces in the angle sensor an effective direction of field lines which differs from the direction of the original state field lines of the angle sensor. The original field direction is imposed on the angle sensor by a biasing magnetic field which originates either from the driver magnet or from a separate biasing magnet.
