Abstract (en)

[origin: DE4436580A1] The proposal is for a gas sensor, especially for internal combustion engine exhaust gases, with a planar sensor component (14) secured in a longitudinal bore (11) of a housing (10) of two superimposed electrically insulating mouldings (24, 25). Between the mouldings (24, 25) there is a first seal (26) tightly surrounding the sensor component (10) which is surrounded in turn by a second seal (27) on the side of the housing (10). The first seal consists of a fuel-resistant powder, e.g. graphite. The second seal (27) consists of an electrically insulating ceramic powder, e.g. aluminium oxide.
