Claim:
1. A sensor device comprising: a first housing with a bottom side, a top side, a face side, a back side, a first side surface, and a second side surface, the face side and the back side and the first and second side surfaces being arranged between the top side and the bottom side; a first semiconductor body with a top surface and a back surface formed in the first housing; a first metal substrate with a front side and a back side; a plurality of terminal contacts arranged on the top surface of the first semiconductor body for electrical contacting of a first magnetic field sensor monolithically integrated with the first semiconductor body, wherein a section of the plurality of terminal contacts penetrates the first housing on the face side, and wherein the first semiconductor body is arranged with the back surface on the front side of the first metal substrate, and wherein the first magnetic field sensor is formed on the top surface of the first semiconductor body, and wherein the first magnetic field sensor comprises a first main extension plane that is arranged parallel to the top surface of the first semiconductor body; a second housing with a bottom side, a top side, a face side, a back side, a first side surface, and a second side surface, the face side and the back side and the first and second side surfaces of the second housing being arranged between the top side and the bottom side of the second housing; a second semiconductor body with a top surface and a back surface is arranged in the second housing; and a second metal substrate with a front side, a back side, and a plurality of second terminal contacts for electrical contacting of a second magnetic field sensor monolithically integrated with the second semiconductor body, wherein a section of the plurality of second terminal contacts penetrates the second housing on the face side, and wherein the second semiconductor body is arranged with the back surface on the front side of the second metal substrate, and wherein the second magnetic field sensor is formed on the top surface of the second semiconductor body, and wherein the second magnetic field sensor comprises a second main extension plane arranged parallel to the top surface of the second semiconductor body, wherein the first and second housings form a module and are connected form-fittingly to one another in the shape of a stack by a fixing device such that the bottom side of the first housing is joined to the bottom side of the second housing or such that the top side of the first housing is joined to the bottom side of the second housing, wherein the plurality of terminal contacts of the first and second housings point in a same direction or the plurality of terminal contacts of the first and second housings penetrates the respective housing on the respective same outer side, wherein a surface normal of the first main extension plane is arranged in parallel to a surface normal of the second main extension plane, and wherein, in a perspective view alongside to the surface normal of the first main extension plane, the first main extension plane overlaps with the second main extension plane so that a divergence in flux strength of an inhomogeneous magnetic field is reduced between the first magnetic field sensor and the second magnetic field sensor.
