The invention relates to a sensor arrangement for seat occupation detection, comprising a fiber-optic sensor network consisting of at least two sensors. The sensor network detest for example local damping modifications in a fiber network that are caused by microbends or modifications of the Bragg wavelength of fiber-optic Bragg grating sensors (FBGS) distributed in the fiber network that are ceased by loads. The optical sensor network is resistant to electromagnetic parasitic inductions. Due to the nature of the optical lass or polymer optical fibers it is for example possible to integrate the network into the textile cover of the seat or into a cushion.

The invention concerns an opto-electronic connector system with a plug and a receptacle The plug includes a tube shaped housing with an area for introduction or output of an optical signal as well as at least one opto-electronic and/or electro-optical transformer and a therewith associated optical element for beam guidance. Beyond this, electrical contacts for input or output of an electrical signal are provided, which are connected with the one or more transformers ( ) via amplifier stage . The tube shaped housing is preferably in the form a cylinder or truncated cone, which engages in a corresponding recess in the receptacle when in the connected condition. The receptacle is adapted for integration on a circuit board. The opto-electronic connector system has been found to be particularly small in its external dimensions.

Plug and receptacle for an opto-electronic plug-in connector system

A connecting housing for optical transmission lines, consisting of an upper and a lower housing part, which are joined in the manner of a snap fastener. Once the housing is connected, a free beam distance appears between the optical transmission lines, in which optical elements are arranged for focussing and/or deflecting the light beam.
