Optoelectronic position measuring device, comprising a code carrier (10), which carries an optically detectable position code (11), a radiation source (20) for emitting optical radiation onto the code carrier (10), and a detection element (30) having a multiplicity of light-sensitive reception regions (31) for receiving at least part of the optical radiation, as a result of which a scanning signal dependent on the position code (11) can be generated and a position of the code carrier (10) relative to the detection element (30) can thus be detected, wherein the measurement components (20, 30) are arranged in a fixed spatial relationship with respect to one another on a carrier element (40), the code carrier (10) is movable with one degree of freedom, in particular rotationally or along an axis, and the code carrier (10) and the carrier element (40) are arranged at a fixed spatial distance (d) with respect to one another, characterized in that of the measurement components (20, 30) at least the one having the greater height (h1, h2) is arranged on the carrier element (40) on a plane lying further away from the code carrier (10) in comparison with the front side (45) in each case such that the projection (h1', h2') of said measurement component above the front side (45) is less than the height (h1, h2) of said measurement component. |
