Reversibly magnetically closeable sensor housing

A sensor housing, comprising:

• a sensor body including a primary retainer disposed in the sensor body;
• a sensor cover including a secondary retainer, wherein the sensor body and the sensor cover are complementarily configured such that the sensor body is rotated relative to the sensor cover to close and open the sensor housing, wherein the secondary retainer is a circumferential groove in a wall of the sensor cover;
• and
• a locking unit including a locking element configured to releasably connect the primary retainer and the secondary retainer,
• wherein the locking element comprises a magnetizable material or a magnetic material and is mounted movably between a locking position, in which the locking element locks the primary retainer relative to the secondary retainer as to prevent rotation and separation of the sensor cover relative to the sensor housing, and a release position, in which the locking element does not lock the primary retainer relative to the secondary retainer, such that the sensor housing can be opened and the sensor cover separated from the sensor body,
• wherein the locking element is configured to be moved between the locking position and the release position by an applied magnetic field.
