Sensor and sensor system for optically detecting objects, insertion head, method for determining the height position of a component

摘要

A sensor has a punctual optical transmission unit transmitting a measuring light. A laminar optical photodiode (328) is adjusted and is arranged for the reception of the measuring light. An evaluating unit is provided downstream to the photodiode and is arranged in such a manner that an object aligned between the unit and the photodiode in the optical path is detected based on the shadowing effects of the measuring light. Independent claims are also included for the following: (1) a sensor system comprising a sensor; (2) an equipment head for accommodating, transporting and attaching an unit; and (3) determining the height position of a unit received by a holding device.
