Abstract: To enable a simple mounting and alignment of an optoelectronic measuring device in its operating position, a fastening system is provided for fastening the optoelectronic measuring device. The fastening system includes a fastening section provided at a surface of a housing of the measuring device. An adjustment adapter has a first element for connection to the fastening section and is provided for the alignment of the measuring device in the operating position. The fastening section rises from the surface of the housing and forms a platform having a groove and a latch cutout at at least one side located perpendicular to the surface of the housing. The first element of the adjustment adapter has a tongue element formed with shape matching the groove and a latching protrusion formed with shape matching the latch cutout. The fastening section and the adjustment adapter are latchinigly connectable to one another without tools.

Abstract: An optoelectronic sensor (10) for detecting objects in a monitored zone (20) is provided which has the following: a front screen (38); a light transmitter (12) for transmitting a light beam (16); a movable deflection unit (18) for the periodic sampling of the monitored zone (20) by the light beam (16); a light receiver (26) for generating a received signal from the light beam (22) remitted by the objects; at least one test light transmitter (42); at least one test light transmitter (42), at least one test light receiver (44) and at least one test light reflector (48) which span a test light path (46a-b) through the front screen (38); and an evaluation unit (32) which is configured to acquire pieces of information on the objects in the monitored zone (20) from the received signal and to recognize an impaired light permeability of the front screen (38) from a test light signal which the test light receiver (44) generates from test light which is transmitted from the test light transmitter (42) and which is refl

Abstract: A fastening apparatus having a base part (4) for fastening and/or adjusting a light grid housing (1) having a partly round housing cross-section (34) in a housing section at an assembly body (12), wherein the base part (4) has an open receiver (24) for the light grid housing (1), wherein the receiver (24) forms a circular section (30) in cross-section and the circular section (30) has an angle (?) of more than 180 degrees, wherein the receiver (24) of the base part (4) is slightly smaller than the partly round housing cross-section (34) of the housing section, wherein the light grid housing (1) is arranged in the receiver (24) and is held by the receiver (24) by force transmission.
