Abstract

An optoelectronic sensor (10) for monitoring a working area (42) is provided, the working area (42) being located within a detection area (20) of the sensor (10) and in a first distance from the sensor (10), wherein the sensor (10) comprises an illumination unit (22) with a light source (24) for at least partially illuminating the working area (42), and an object detection unit (30) for detecting forbidden objects in the working area (42), wherein an illumination control (28) of the illumination unit (22) is configured to, during a startup period, The illumination control (28) comprises a short range object detection unit (39) configured to test the provisional working area (40, 40a-c) in a different way than the object detection unit (30) tests the working area (42).
