Sensor e.g. optical sensor, for detecting object in detecting range, has actuating unit in mechanical contact with contact unit during rotation of adjusting unit in rotating direction, where adjusting unit is rotatable around rotation axis

摘要

The sensor (1) has an adjusting unit (11) that is rotatable around an axis of rotation. The adjusting unit is connected with an actuating unit (12) such that the actuating unit is in mechanical contact with a contact unit (13a) during rotation of the adjusting unit in a rotating direction. The actuating unit is in mechanical contact with another contact unit (13b) during rotation of the adjusting unit in another rotating direction. The actuating unit is not in mechanical contact with the contact units in a null point position of the adjusting unit.
