摘要： The invention relates to an optoelectronic sensor, in particular to a light grid (10), having at least two circuit boards (19, 19-x) which are to be arranged one after the other in a longitudinal direction (16, z direction) and on which a plurality of light transmitters (18) and/or light receivers (20) are arranged in series, wherein the circuit boards (19-1, 19-2) are fixed in a desired position with respect to one another by a functional element (34) and wherein the circuit boards (19-1, 19-2) are held in a housing (12). It is proposed to provide an improved optoelectronic sensor, in particular a light grid, that the housing (12) is configured as a section and the circuit boards (19-1, 19-2) are held via the functional elements (34) in oppositely disposed grooves (50, 52) of the section (12) which extend in the longitudinal direction (16, z direction) so that the functional elements (34) position the circuit boards (19-1, 19-2) in a fixed position perpendicular (in the x-y plane) to the longitudinal direction (16, z direction).

摘要： A flow rack unit for providing stock material units includes at least two rack bays and one control system. Each rack bay has a removal side and a storage side opposite the removal side and is configured to provide the stock material units in a respective bay level arranged next to one another starting in the direction of the storage side. A respective sensor arrangement of the control system is associated with each rack bay. Each sensor arrangement is arranged at the storage side of the associated rack bay and connected to a control unit of the control system via a common data line. The sensor arrangements each include an occupancy sensor configured as a distance sensor. Each occupancy sensor has a measurement zone that is aligned to measure a distance from a rearmost stock material unit stored in the associated rack bay and disposed closest to the occupancy sensor.

摘要： A light grid and a method using a light grid include a transmission unit having a plurality of light transmitters for transmitting light beams and a reception unit having a plurality of light receivers for receiving the light beams of the light transmitters. The transmission unit and the reception unit are spaced apart from one another and are disposed opposite one another. A monitored field is formed by oppositely disposed light transmitters and light receivers for detecting objects. The light transmitters are activated one after the other in cycles and the light receivers are evaluated in these cycles. A programmable evaluation unit is provided for evaluating the received signals of the light receivers of a cycle with reference to predefined beam evaluation criteria and forming an intermediate result therefrom. The evaluation unit evaluates at least one intermediate result of a cycle with reference to at least one predefined sequential criterion.
