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

Optoelectronic sensor having at least two circuit boards held via functional elements

An optoelectronic sensor arrangement comprising a light transmitter for the transmission of sequential operational light pulses into a monitored region and with a light receiver unit for the reception of operational light pulses reflected from an object located in the monitored region, wherein the light receiver unit includes at least two photosensitive elements, with a circuit for the suppression of stray light being associated with each photo-sensitive element.

Optoelectronic sensor arrangement with a plurality of photosensitive

An opto-electronic sensor for recognizing transparent articles, such as, for example, glass bodies, plastic bodies, or foils. The sensor includes at least one transmitter for transmitting light signals into a monitored region, at least one receiver for receiving the transmitted light signals, and at least one evaluation unit for the evaluation of the received signals. The transmitter is designed for the transmission of the light signals in the UV range. At least one reference transmitter is provided for the transmission of light signals into the monitored region. The light signals transmitted by the reference transmitter lie in a different frequency range from the light signals transmitted by the transmitter.

Opto-electronic sensor

An optical arrangement, in particular for use as a transmitting and/or receiving optical system in optoelectronic sensors, comprises at least one diffractive optical element integrated into transparent material, with the unit formed by the transparent material and the diffractive optical element having at least two different functions such as, for example, image forming functions, polarization, beam division, beam forming, beam shaping and/or the provision of a subaperture.
