Abstract

A sensor arrangement (1) for a tachometric sensor of an automatic transmission (4) of a motor vehicle, which encompasses a module carrier (2) in which a part of a sensor housing (3) is integrated. The sensor housing (3) is secured in the module carrier (2) or in the transmission housing (4) by way of a guide in the plane and is so affixed as to prevent turning and an apparatus (5) for the generation of a prestress force by way of which the sensor housing (3) is pressed in the direction of the signal disk by way of a projection (8, 8′) acting against the sensor housing (3).
