Abstract
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.
