Claim:
1. An ABS encoder system comprising: a multi-pole ring carrying a multi-pole structure; a sensor device having a sensor head for detecting a magnetic field generated by the multi-pole structure; and an annular cap element having an annular wall section sealing off a cap interior toward the outside, the cap interior housing the multi-pole ring; the annular wall section extending through an intermediate area situated between the multi-pole ring and a front surface of the sensor head, an extension concentrical to the circumferential axis of the multi-pole ring being connected to the annular wall section, and axially overlapping in a mounting position a circumferential area of a drive shaft head, the extension, in an end area facing away from the multi-pole ring and surrounding the drive shaft head, forming a circumferential profile radially stiffening the extension; the circumferential profile forming an annular border extending axially away from the multi-pole ring into a circumferential groove of the drive shaft head, and the annular border forms a channel cross-section open to the outside.
