ABSTRACT:
This invention concerns an optoelectronic sensor assembly (10) with at least one light emitter (20) and at least one light receiver (30) comprising a spatially resolving receiving element (40), with the receiving element (40) having an inner region (42) comprising at least one photosensitive element (45) for detecting the light beam (25) and an outer region (44) comprising at least one photosensitive element (46, 47, 48, 49) for determining the position of the light beam (25) emitted by the light emitter (20), with the outer region (44) satisfying lower sensitivity and/or bandwidth requirements than the inner region (42).
