Abstract

For a gas sensor, in particular for automobile applications, comprising a housing, which has a measurement chamber, wherein at least one sensor element having connecting wires is associated with the measurement chamber, the housing has a bottom part and a top part that covers the bottom part and each sensor element is arranged in the bottom part while suspended by the connecting wires thereof. At least one side wall of the bottom part favorably has an assembly opening, which is designed in such a way that a tool arm that retains the sensor element can be inserted into the bottom part from the outside through the assembly opening and can be brought into an assembly position in the area of the opening edge of the bottom part so that the connecting wires of the sensor element are in bondable contact with the associated connection surfaces. Thus especially easy assembly is possible.
