Additionally, the sensor has a holder for the component, having a recess or a hole for at least partially accommodating the component, in which the electrical component is held, and on or in which at least one conductive path extends to contact with at least one electrical contact of the electrical component. ## Claims ### Claim 1 A sensor for examining a document of value in a detection range of the sensor comprising at least one ultrasonic converter that converts electrical energy into sound waves useable for examining the document of value and/or detecting sound waves from the document, said ultrasonic converter generating detection signals, and a holder for the ultrasonic converter, having a recess or a hole that accommodates at least partially the ultrasonic converter and in which the ultrasonic converter is held, and on or in which at least one conductive path extends that contacts at least one electrical contact of the ultrasonic converter. ### Claim 2 (depends on 1) The sensor according to claim 1, wherein the holder is formed in a single-piece. ### Claim 3 (depends on 1) The sensor according to claim 1, wherein said holder is plate-shaped. ### Claim 4 (depends on 1) The sensor according to claim 1, wherein the conductive path is arranged on a surface of the holder which faces away from the document of value during an examination, or faces away from an emission or reception surface of the ultrasonic converter. ### Claim 5 (depends on 1) The sensor according to claim 1, wherein the ultrasonic converter is oriented using at least one surface section of a wall forming the recess or the hole and/or an orientation structure of the wall in relation to the holder. ### Claim 6 (depends on 5) The sensor according to claim 5, wherein the surface section or the orientation structure and the ultrasonic converter are arranged such that a main emission direction or a main reception direction of the ultrasonic converter is inclined in relation to a surface of the holder. ### Claim 7 (depends on 4) The sensor according to claim 4, wherein the orientation structure has a shoulder extending around the recess or the hole or a groove on an inside wall of the recess or of the hole. ### Claim 8 (depends on 1) The sensor according to claim 1, wherein the recess or the hole comprises a duct extending through the holder. ### Claim 9 (depends on 1) The sensor according to claim 1, wherein the recess or the hole is symmetrical about an axis that extends in predetermined relationship relative to the holder. ### Claim 10 (depends on 1) The sensor according to claim 1, wherein the recess or the hole is inclined in relation to a surface of the holder. ### Claim 11 (depends on 1) The sensor according to claim 1, wherein the recess or the hole has a bottom that is inclined in relation to a surface of the holder, said ultrasonic converter being disposed on said bottom. ### Claim 12 (depends on 1) The sensor according to claim 1, wherein the ultrasonic converter is cast at least partially in the recess or the hole. ### Claim 13 (depends on 1) The sensor according to claim 1, wherein, on a surface of the holder or in the holder, an electrically conductive shielding layer is provided. ### Claim 14 (depends on 1) The sensor according to claim 1, including a wire by which the ultrasonic converter contacts the conductive path. ### Claim 15 (depends on 1) The sensor according to claim 1, wherein the holder has a plug-in contact or clip-on contact electrically connected to the conductive path, and the ultrasonic converter has a complementary plug-in contact or clip-on contact plugged into or clipped on the plug-in contact or clip-on contact. ### Claim 16 (depends on 1) The sensor according to claim 1, wherein the ultrasonic converter comprises an SMD and is directly electrically connected with the conductive path. ### Claim 17 (depends on 1) The sensor according to claim 1, including a further ultrasonic converter that converts electrical energy into sound waves useable for examining the document of value and/or for detecting sound waves from the document of value, said further ultrasonic converter generating detection signals, wherein the holder has at least one further recess or one further hole in which the further ultrasonic converter is arranged at least partially, as well as a further conductive path that contacts at least one electrical contact of the further ultrasonic converter. ### Claim 18 (depends on 17) The sensor according to claim 17, wherein the at least one ultrasonic converter is configured as an emitter with a direction-dependent emission characteristic, and the further ultrasonic converter is configured as a receiver with a direction-dependent receiving characteristic, said
