Optical module and optical unit for a light curtain, and fabrication method

摘要

The present invention relates to industrial light curtains which monitor a protective or surveillance field and in particular relates to optical modules within optical units that can be used for such a light curtain. The present invention in particular relates to an interconnection element for connecting an optical module (100) for an optical unit (150) of a light curtain monitoring a protective field to another optical module and/or to a control module. The optical module (100) comprises at least one radiation emitting and/or radiation receiving element (116) for transmitting and/or receiving a radiation beam forming said light curtain, and a module body (108) for mounting a radiation transmitter/receiver carrier (102) carrying the at least one transmitting and/or receiving element (116) for transmitting and/or receiving said radiation. Said interconnection element (152) is formed to electrically connect as well as mechanically fix the optical module and the other optical module and/or control module in respect to each other.
