Part number BES0356 (a.k.a. BES 516-324-SA56-E5-C-S49 is an inductive proximity sensor with an NO PNP output sold by Balluff. We do not carry it, and further Balluff has marked it as not recommended for new designs. You can find the manufacturer’s specifications linked in the part number.
If you are in need of a replacement part, I’d recommend Z13177-ND, made by Omron. The datasheet for this part is linked below, please review as there are several similar sensors out there, but there is not a direct cross-reference item to my knowledge.
