Gas sensor

A gas sensor, in particular for exhaust gases of internal combustion engines, has a planar sensor element 2, which is situated in a tubular housing 4 and fixed in a longitudinal bore of a ceramic support 3 which separates a reference gas chamber 22 from an exhaust gas chamber 21, the housing being a one-piece sleeve having at least one external thread 8 and having over its entire periphery a shoulder 5, which is directed into the sleeve interior and disposed on which is a sealing collar 6 of an inner protective sleeve 7 which surrounds the exhaust-side region 25 of the sensor element. Various sealing arrangements for the cable outlet region 18 of the sensor are also disclosed (Figures 2-4) each comprising an elastomeric element 10 and a cap 11.
