Abstract

An optoelectronic sensor module is provided for recognition of reflection patterns on a magnetic data carrier. A laser component having a laser radiation axis, at least a first sensor photodetector laterally displaced relative to the laser radiation axis, electrically conducting bond pads and mutually electrically insulated conducting paths, are disposed on or in a silicon submount or cooling element. A lens configuration which is provided at a side of the laser emitter component opposite the cooling element, is fixed on the cooling element by at least one supporting web.
