An optoelectronic sensor module (1) for recognising reflection models on a magnetic data carrier (14). A laser component (8), at least one first sensor-photodetector which is laterally offset in relation to the laser beam axis (19), electrically conductive contact surfaces (20-25) and electrically insulated printed conductors (33) are arranged on or in a silicon submount (3). A lens arrangement (9,10) is provided on the side of the laser emitter component (8) opposite the cooler element (3). Said lens arrangement is secured to the cooling element (3) by at least one supporting bar(29,30).
