Abstract
A sensing element for determining a physical property of a gas mixture, in particular the exhaust gas of internal combustion engines, includes a sensor element, arranged in a housing and connected to at least one electrical cable, as well as a molded piece, which seals the housing and is made of an elastically deformable material, which encloses the at least one cable in a gas-tight manner by radial compression. To ensure the gas-tightness of the cable feed-through also under a higher temperature load, which results in decreased elasticity of the molded piece, a spring element is arranged inside the molded piece, which is able to be tensioned by the radial compression and in the tensioned state generates a force component that acts on the cables in a radial direction.
