A yarn sensor ( 25 ) for monitoring at least one parameter of a traveling yarn ( 17 ), e.g., in spinning and bobbin-winding machines, has a measuring gap ( 16 ) and a housing made of a non-conductive plastic material for containing electronic components. The housing surface is covered by a metallic coating such that the electronic components are surrounded by the coating ( 21 ). At least a portion of the surface inside the measuring gap ( 16 ) is free of the coating ( 21 ). The metallic coating is connected with a heat conductor to remove heat via the metallic coating ( 21 ). Undesirable effects on the measurement results can be substantially reduced, and the quality of the measurement results can be increased.
