Omron E3S-AT81-L2M Photoelectric Sensor

The Omron E3S-AT81-L2M is a photoelectric sensor used in industrial automation to detect the presence, absence, or position of objects without contact. This is the kind of spare you want one in the cabinet before the line-down call — no datasheet on hand, but the form factor and wiring pattern match the classic E3S series footprint. Sourced to order against an RFQ for your BOM line; confirm the sensing range and output type from your existing installation documentation.
