Photoelectric sensor with weld connection between housing and optical module

A photoelectric sensor, in particular a light curtain, comprising:

• an elongated housing and
• an optical module which is arranged in the housing, wherein
• transmitting and/or receiving elements are arranged at the optical module at a distance from one another,
• the optics module is connected to the housing via contact points, and
• the optical module and the housing comprise plastic,
• wherein
• at least some of the contact points between the optics module and the housing are designed as welded connections and the welded connection between the housing and the optics module is formed by laser transmission welding.

A method for producing a photoelectric sensor comprising an elongate housing and an optical module arranged in the housing, the method comprising:

• transmitting and/or receiving elements being arranged on the optical module,
• the optical module being inserted into the housing and
• aligned therein,
• wherein
• the optical module is connected to the housing by laser transmission welding.
