Abstract: A sensor device for a commercial vehicle, in particular a speed sensor, has a chip with a sensor, which is provided in a housing. The chip is arranged in a watertight manner with respect to the environment, and no metal is provided between the chip and the object to be sensed. Interfering eddy currents can be avoided and a long service life of the sensor can be achieved by the water-tightness.

Abstract: A sensor for detecting a rotational speed and/or direction of rotation of a wheel of a vehicle. The sensor includes a first magnetic field sensor chip and a second magnetic field sensor chip, wherein the first and second magnetic field sensor chips are each independently configured to output a sensor signal indicative of a change in a biased magnetic field under the influence of a rotating pole wheel coupled to the wheel of the vehicle. The sensor includes a first receptacle through which the first magnetic field sensor chip is received and a second receptacle through which the second magnetic field sensor chip is received. The sensor also includes at least one permanent magnet for generating the biased magnetic field, wherein the at least one permanent magnet (18) is disposed in the receiving body at one or both of the first and second receptacles.

Abstract: Described is a connecting part for a plug-in connection system of a coupling device for automatically coupling a trailer vehicle to a towing vehicle, comprising: a contact carrier, a contact structure mounted on the contact carrier and engageable with a contact structure of a complementary connecting part of the plug-in connection system to establish a plug-in connection with the complementary connecting part during automatic coupling, a closure flap pivotable relative to the contact carrier, which is biased onto the contract carrier and is releasable from the contact carrier in a pivoting movement against this bias when the plug-in connection is established, and a seal which is arranged on the contact carrier and is elastically deformable by a counterpart pressing on the seal in order to seal the contact structure with respect to the exterior space, wherein the counterpart is formed by the closure flap pressing on the seal when the plug-in connection is disconnected and by the complementary connecting part o
