Patent ID: 8305072

Claim:
A sensor unit, comprising: a sensor protective profile ( 1 ), configured as a hollow, circumferentially closed profile ( 1 ) with a cross section contour in longitudinal direction ( 10 ), which is in particular continuous; a travel distance measurement sensor in the interior of the profile ( 1 ), comprising: a wave conductor unit ( 2 ), wherein the wave conductor ( 3 ) of the wave conductor unit ( 2 ) extends in longtidunal direction ( 10 ) of the profile ( 1 ); a circuit board ( 4 ) with processing electronics ( 5 ) in the interior of the profile ( 1 ), whose main extension runs in the longitudinal direction ( 10 ) of the profile ( 1 ); the sensor unit comprises a headpiece ( 6 ), which comprises form locked mounting devices for the wave conductor unit ( 2 ) and for the circuit board ( 4 ); and the headpiece ( 6 ) with the conductor unit ( 2 ) and the circuit board ( 4 ) form a subassembly 23 , which is at least partially disposed in the free inner cross section ( 1 ′) of the profile ( 1 ).
