Lanbao PST-SR - diffuse photoelectric sensor The Lanbao PST-SR is a diffuse photoelectric sensor built for diffuse reflection sensing in industrial automation equipment. Lanbao's official specification lists 2...25mm, NPN NO; NPN NC; PNP NO; PNP NC (based on current SKU options), 10...30VDC supply, and 2m PVC cable/20cm PVC+M8 connector (3-pins). This OpenELAB listing summarizes the product family for selectable SKUs, so always match the required output and connection against the variant name before ordering. For selection, confirm the sensing principle, range, output type, connection style, response time, protection rating, and accessory set against the exact SKU. Use the SKU code on the order page as the final reference for output polarity and cable style. If you are comparing nearby Lanbao models, also review Lanbao PST-YC10-S, Lanbao PST-YR30-S, and Lanbao PU05S so the housing style, measurement method, and control output match the machine input.
