Abstract
The invention relates to a yarn sensor for scanning a yarn (2), which is moving in its longitudinal direction in a measuring gap (3), with a light beam from a light source (4), having a first receiver (7) for directly transmitted light, at least one second receiver (5, 6) for light reflected by the yarn and one element each (8, 9, 10, 11) for transmitting the light between the measuring gap, the light source and a receiver. To keep the overall size and the external dimensions as small as possible, the optical axes (12-15) of the elements for transmitting the light are disposed together in one plane lying at least approximately at right angles to the yarn.
