摘要： A sensor for determining an oxygen content in an exhaust gas of an internal combustion engine includes a receptacle, arranged in a longitudinal bore of a metal housing, for a sensing element. The sensing element is received in the receptacle in a gas-tight fashion via a sensing element seal, which includes a glass seal. The receptacle has a measured-gas-side ceramic shaped element and a connector-side ceramic shaped element, which are arranged axially one behind the other. A cavity into which the glass seal is pressed while hot is configured between the two ceramic shaped elements.
