A safety circuit for motorized units, comprises a light source, a light guide (1), a light sensor, and a control unit. The light intensity that is picked up controls the installation. A safety circuit for motorized units, comprises a light source, a light guide (1), a light sensor, and a control unit. The light intensity that is picked up controls the installation. The light wave guide has a core (2) with a high refractive index and a surrounding outer wall (3) with a lower refractive index. The core and/or the outer wall consist of a material which is elastically deformable in finished light wave guides. |
