Abstract
A sensor arrangement for measuring a speed of a rotating component includes a rotary encoder and sensor unit. The encoder is coupled to the component, and has a magnetic surface code with alternating North and South poles. The sensor unit has a housing, connecting cable, at least one sensitive measuring element, and contacting arrangement. The element is positioned in the sensor unit such that a main detection direction of the element is angled relative to a main extension direction of the sensor unit. The contacting arrangement electrically connects the element to the cable within the housing. Rotational movement of the encoder changes a magnetic field generated by the code at the element, which is configured to detect the change over a first direction parallel to the main extension direction or over a second direction perpendicular to the main extension direction in order to determine the speed of the component.
