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).

The invention claimed is: 1. A sensor arrangement for a tachometric sensor of an automatic transmission of a motor vehicle, the sensor arrangement comprising: a sensor housing (3) containing a tachometric sensor, and a module carrier (2), a first portion of the sensor housing (3) being located in and axially moveable in a sensor housing opening in a transmission housing (4), and a second portion of the sensor housing (3) being located in and axially moveable in the module carrier (2), the sensor housing (3) being non-rotationally fixed in at least one of the module carrier (2) and the sensor housing opening in the transmission housing (4) by a guide, a first detent (6) surface located at and circumferential to the sensor housing opening in the transmission housing (4) and facing toward and coaxial with the module carrier (2), the sensor housing (3) having a second detent surface (8) circumferential to the sensor housing (3) and facing toward and coaxial with the sensor housing opening in the transmission housing (4), a resilient apparatus (5) acting between the sensor housing (3) and the module carrier (2) to generate a resilient prestress force by which the sensor housing (3) is resiliently and axially biased toward the transmission housing (4) so that the second detent surface on the sensor housing (3) bears against the first detent (6) surface, on the transmission housing (4), whereby the sensor housing (3) is axially positioned in the sensor housing opening at a predetermined axial position that is determined by the locations of the first and second detent surfaces (6, 8). 2. The sensor arrangement according to claim 1, wherein the detent (6) is provided in one of the module carrier (2) and in the transmission housing (4). 3. The sensor arrangement according to claim 1, wherein the detent (6) is provided on the transmission housing (4) and the detent (6) is formed by an additional element which functions as the detent (6). 4. The sensor arrangement according to claim 3, wherein the additional element, which functions as the detent (6) on the transmission housing (4), is a sleeve which is one of snapped on, force-fit installed, and screwed into place. 5. The sensor arrangement according to claim 1, wherein the detent (6) is provided on the transmission housing (4), and the detent (6) is formed by machining a side of the transmission housing (4) which is proximal to the sensor housing (3). 6. The sensor arrangement according to claim 1, wherein the detent (6) is provided on the transmission housing (4), a shell slidingly encapsulates the sensor housing (3) which is subjected to a pushing force, by the apparatus (5), for generation of the prestress force against the transmission housing (4). 7. The sensor arrangement according to claim 1, wherein a boring (12) which penetrates the transmission housing (4) has different depths, to accommodate a required length of the sensor, which form the detent (8, 8') by varied projections on the sensor housing (3). 8. The sensor arrangement according to claim 1, wherein the apparatus (5) for the generating of the prestressed force is a spring element (5). 9. The sensor arrangement according to claim 8, wherein the spring element (5) is placed between, a side of the module carrier (2) proximal to the transmission housing (4) and the projection (8) on the sensor housing (3) whereby a friction fit of the sensor housing (3) in the module carrier (2) is provided. 10. The sensor arrangement according to claim 8, wherein the spring element (5) is placed within the module carrier (2) between an inner wall (10) and an abutment (9) of the sensor housing (3). 11. The sensor arrangement according to claim 8, wherein the spring element (5) is placed within the module carrier (2) between an inner wall (10) and a side of the sensor housing (3) remote from the transmission housing (4). 12. The sensor arrangement according to claim 1, wherein an electrical contact (7) of the sensor is one of a flexible electrical and a non-wired connection such that relative movement between the sensor housing (3) and the module carrier (2) is facilitated. 13. The sensor arrangement according to claim 12, wherein the electrical contact (7) is one of a stamped grid, a flexible conducting plate, a conducting foil, a cable bundle and a non-wired transponder. 14. The sensor arrangement according to claim 1, wherein different sensor-lengths, by corresponding formation and sensor (6) dimensions, determine a use of the sensor.
