A sensor assembly for a vehicle includes (i) a plug assembly which having a plug housing and at least two plug pins and forms an external interface of the sensor assembly, (ii) a circuit carrier on which an electronic circuit corresponding to a sensor concept being implemented is arranged, and (iii) a sensor housing which comprises an insertion opening. The circuit carrier is connected to the plug housing and the at least two plug pins at a first interface. The sensor housing includes a second interface having an opening via which the sensor housing can be connected to an external sensor arrangement or a cover according to the sensor concept being implemented, which covers the opening of the third interface in the unused state. The circuit carrier is inserted into the sensor housing through the insertion opening which is connected to the plug housing via a third interface. The circuit carrier is pre-fixed at an end region of the sensor housing. A guide element guides the circuit carrier on a first side and at least one spring element adjoins a second side opposite the first side and presses and fixes the circuit carrier against the guide element. The first interface and the external interface are arranged according to a function of a communication protocol being implemented. The second interface and the third interface are designed in the same way, independent of the sensor concept being implemented and the communication protocol being implemented. An associated method for mounting such a sensor assembly is also disclosed.

Sensor assembly for a vehicle

An encoder wheel assembly comprising: a first encoder wheel rotationally fixed to a rotor and having a number n of teeth arranged along the circumference of the encoder wheel; a second encoder wheel rotationally fixed to the first encoder wheel, and having the same number n of teeth as the first encoder wheel along the circumference of the encoder wheel, wherein the teeth of the second encoder wheel have an asymmetrical angular offset relative to the teeth of the first encoder wheel; a first sensor designed to scan the first encoder wheel; a second sensor designed to scan the second encoder wheel; and a controller connected to the first sensor and the second sensor and designed to ascertain the absolute angular position and the rotational direction based on a binary signal derived from a first signal of the first sensor and a second signal of the second sensor.
